Determination of 15 3-chloro-1,2-propanediol fatty acid esters in vegetable oils and fritters by ultra performance convergence chromatography-tandem mass spectrometry

The presence of 3-chloro-1,2-propanediol fatty acid esters ( 3-MCPDE) in food and processed materials has recently become a topic of concern because of the toxicity of their metabolites. 3-MCPDE structurally similar to glyceride, which makes it difficult to separate or extract them from oils and fritters. A method based on ultra performance convergence chromatography-tandem mass spectrometry ( UPC2-MS/ MS) was established for the determination of 15 3-MCPDE in vegetable oils and fritters. Amino. packed columns were used to purify the samples. The analytical conditions were optimized, and the matrix effect was investigated. The sample was treated by column chromatography to remove glyceride and free fatty acids, which induce strong matrix effects. The amino. packed column was eluted with hexane and hexane-ethyl acetate ( 6 : 4, v / v). Every 1 mL of the eluent was analyzed using a UPC2 and ACQUITY QDa detector. Elution curves were drawn based on the testing data and used to determine the collection volume. The collection volumes for 3-chloro-1,2-propanediol diesters and monoesters according to the elution curves were 7-14 mL and 3- 9 mL. The collected eluent was mixed and dried under nitrogen flow at a temperature of 60 degrees C. A hexane. isopropanol ( 98 : 2, v / v, 1 mL) mixture was used to dissolve the residue. The resulting solution was separated on a Viridis HSS C18 SB column ( 150 mmx2. 1 mm, 1. 8 mu m) under gradient elution. Supercritical carbon dioxide and methanol ( containing 40% acetonitrile and 0. 1% formic acid) were used as the mobile phases, and the flow rate was 1 mL / min. The separated compounds were analyzed by tandem MS with an electrospray ionization ( ESI) source in positive and multiple reaction monitoring modes. Water ( containing 97% isopropanol and 0. 2% ammonia water) was used as the auxiliary pump mobile phase, and the flow rate was 0. 2 mL / min. The method showed good linear relationships in the range of 0. 5-100 mu g / L ( r(2)>= 0. 997 3). The limits of detection ( LODs) and limits of quantification ( LOQs) were 0. 01-0. 68 mu g / L ( S / N = 3) and 0. 04-1. 74 mu g / L ( S / N = 10), respectively. The average recoveries ( n = 9) at the three spiked levels were in the range of 81. 6%-98. 5%. The relative standard deviations were in the range of 1. 8%-6. 4%. The matrix effects in the case of the oils and fritters were weak. The developed method was used to detect 44 oil samples and eight fritter samples. Meanwhile, some suspect 3-MCPDE compounds outside the scope of the investigation were analyzed based on their primary and secondary mass spectra. The detection rates of 3-MCPDE in oils and fritters were 84. 1% and 87. 5%, and their amounts were in the range of 0. 024-4. 481 mg / kg and 0. 018- 1. 144 mg / kg, respectively. The detection rates of 3-MCPDE in rapeseed oil were higher compared to those for other kinds of oil. The method is specific, fast, simple, accurate, reliable, and environmentally friendly, in addition to being more sensitive than other methods and showing better matrix compatibility for oils. This method has been successfully used to determine the types and amounts of 3-MCPDE in vegetable oils and fritters. The research findings provided accurate data to assess the exposure risk of 3-MCPDE. The results of our experiment also provided valuable information for elucidating the formation mechanism of 3-MCPDE. The proposed method can be used to analyze waste edible oil based on large amounts of analysis data. However, this method has some limitations. The resolution ratio of the mass spectrometer used in this method is too low for the qualitative analysis of unknown compounds. The qualitative results for the suspect 3-MCPDE compounds are not particularly accurate, and a large variety of monomer standards are required for the quantitative determination of 3-MCPDE. The 3-MCPDE standards are expensive, and there is limited choice of these standards; moreover, they are difficult to synthesize. The poor ionization yield of 3-chloro-1,2-propanediol monoesters under the ESI conditions resulted in high LODs. Hence, it is necessary to develop a method for increasing the ionization of monoesters, for example, via derivatization.

Enzyme Inhibitory Kinetics and Molecular Docking Studies of Halo-Substituted Mixed Ester/Amide-Based Derivatives as Jack Bean Urease Inhibitors

A series of halo-substituted mixed ester/amide-based analogues 4a-l have been prepared as jack bean urease inhibitor, which showed good to excellent inhibition of enzyme activity. The role of halo-substituted benzoyl moieties and alkyl substituted anilines in urease inhibitory kinetics was also investigated. The alkyl-substituted anilines 1a-b reacted with chloroacetyl chloride to afford intermediates 2a-b, which were then reacted with different halo-substituted benzoic acids 3a-f to prepare the title compounds 4a-l. The chemical structures of final products 4a-l were ascertained by FTIR, H-1 NMR, C-13 NMR, and mass spectra. The compound 4b showed remarkable activity with IC(50)1.6 +/- 0.2 nM, better than the standard thiourea having IC(50)472.1 +/- 135.1 nM. The 2-chloro-substituted phenyl ring on one side of compound 4b and 4-isopropyl-substituted benzene on the other side play an essential role in inhibition of urease activity. Lineweaver-Burk plots (kinetics study) indicated about 4b derivative as a mixed type of inhibitor. The virtual screening performed against urease enzyme (PDBID 4H9M) showed that compounds 4b and 4e have binding energies of -7.8 and -7.9 Kcal/mol, respectively. Based upon our results, it was found that derivative 4b is a highly potent urease inhibitor, better than the standard thiourea.

Oxygen-Rich Bis(trinitroethyl esters): Suitable Oxidizers as Potential Ammonium Perchlorate Replacements

In the area of solid rocket propellants, research efforts are ongoing to find suitable oxidizers as ammonium perchlorate (AP) replacements. On the one hand, AP’s performance data are excellent; on the other hand, AP and its combustion products lead to health and environmental issues. Herein, the nitraminodiacetic acid bis(2,2,2-trinitroethyl ester) (NABTNE) is presented as a green AP alternative and is compared to the bis(trinitroethyl ester) of malonic acid (MaBTNE). Simple syntheses based on economic starting materials furnished both compounds, with NABTNE having a positive oxygen balance (according to CO), a density of 1.84 g cm(-3) (@T = -118 degrees C), and a decomposition point of 180 degrees C. The density of MaBTNE (delta = 1.81 g cm(-3) @T = -147 degrees C) and the thermal stability (T-dec = 157 degrees C) are also advantageous. NABTNE as a moderately sensitive and the most promising derivative was shown to be of good stability toward long-term storage. Moreover, mixtures for a potential application in solid rocket formulations were calculated using EXPLOS (V 6.03).

Infectious Effect of Organic Small Molecules on Photo-oxidative Aging of Polypropylene

Aging of a polymer is generally affected by adjacent polymers, known as infectious behavior of aging. Organic small molecules generated during aging are considered to be infection agents. However, the way they influence aging process and the difference among various infection agents are still unknown. In this paper, the influence of 18 representative organic small molecules on photo-oxidative aging of polypropylene (PP) was studied. The small molecules included acids, esters, aldehydes, ketones and alcohols, corresponding to typical photo-oxidative degradation products of polymers. When they were placed near PP during aging, the carbonyl index (CI) of PP was higher compared to the case when PP was aged individually. It was demonstrated that photo-oxidative aging of PP was accelerated by all the small molecules. The acceleration effects of acids, aldehydes and ketones were outstanding. Especially for propanoic acid, isobutyric acid, methacrylic acid, formaldehyde, acetaldehyde and butanone, CI was increased by more than 700% when PP was aged with them. Further, infection mechanism of acetone and acetic acid was investigated , since they had been identified as typical infection agents. CI and concentrations of gaseous degradation products of PP with and without acetone or acetic acid were measured with aging time. When PP was aged with acetone, CI was increased from as early as 24 h at an extremely high rate. With acetic acid, CI was increased after an obvious induction period and the increasing rate was lower than that with acetone. Similar phenomenon was observed in gaseous degradation products. The results showed that acetone acted as an initiator, photolyzed to generate CH3 center dot that could initiate the oxidation of PP; while acetic acid acted as a catalyzer, facilitating the decomposition of hydroperoxides and the accumulation of oxidation products.

I+/TBHP Catalysis For Tandem Oxidative Cyclization To Indolo[2,3-b]quinolines

We report a chemoselective tandem oxidative cyclization/aromatization of indole derivatives tethered to aniline sulfonamides using catalytic amount of tetrabutylammonium iodide in the presence of tert-butyl hydroperoxide (TBHP) as an oxidant under nearly neutral conditions at room temperature. The corresponding indolo[2,3-b]quinolines were obtained as sulfonate salts, which could be easily isolated in analytically pure form via only a simple filtration of the crude reaction mixture. The natural product quinindoline could be easily obtained after basic work-up of the sulfonate salt. Control experiments revealed that both ionic and radical active species could be generated in situ under mild conditions for the corresponding oxidative transformations to proceed in a chemoselective manner.

Optimisation and prediction of Karanja oil transesterification with domestic microwave by RSM and ANN

Optimisation and estimation of biodiesel by Karanja oil (KO) was done by response surface methodology (RSM) and artificial neural networks (ANNs) models through domestic microwave heating transesterification. Box-Behnken experimental design was adopted. Four process parameters are methanol/oil mole ratio (30-50%), catalyst concentration (1-2 wt%), volume (100-300 mL) and time (4-8 min). Biodiesel with a yield of 87.34% was obtained using 1.5 wt. % NaOH, 35% methanol to oil molar ratio, 150 mL amount and 5 min of reaction at 700 W power with 100 rpm stirring. The physico-chemical characteristics of KO methyl ester are measured using standard methods. Quality of RSM model is analysed by analysis of variance. ANN tool was adopted for modelling and prediction. Correlation coefficient values were 0.85 and 0.8663 with RSM and ANN, respectively. The concentration of the catalyst, volume, methanol to oil molar ratio and time required producing maximum yield of biodiesel were obtained. The predictive capacities of RSM and ANN are evaluated and compared by statistical parameters, namely, R-2, RMSE, ADJ-R-2 and MSE. Hence, results typify the strength and excellence of ANN over RSM specifically in the transesterification of biodiesel.
