Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, Safety of Dioctyl maleate, 2915-53-9, Name is Dioctyl maleate, SMILES is O=C(OCCCCCCCC)/C=CC(OCCCCCCCC)=O, belongs to esters-buliding-blocks compound. In a document, author is Shaari, Noor Asma, introduce the new discover.
In-house validation of accelerated solvent extraction-gas chromatography-mass spectrometry for the determination of bound 3-and 2-monochloropropanediols (MCPD) and glycidol in food products
The study aimed to establish the detection method for bound 3-, 2-MCPD, and glycidol using accelerated solvent extraction (ASE) and gas chromatography mass spectrometry (GC-MS). The ASE was modified for reduced solvent volume and process time to extract lipid from the chocolate spread, infant formula, potato chips, and sweetened creamer. The solvent selected for ASE was a mixture of iso-hexane and acetone at 100 degrees C with the lipid and analyte recovery ranging from 96.9% to 98.6% and 84.1% to 107.5%, respectively. The derivatisation of analytes was adopted from the AOCS method Cd29a-13 for GC-MS analysis. The results showed that the coefficient of determination (R-2) of all analytes was >0.99. The limit of detection (LOD) was 0.1 mg kg(-1) expressed in lipid basis for both bound 3- and 2-MCPD and 0.2 mg kg(-1) expressed in lipid basis for bound glycidol. The limit of quantitation (LOQ) was 0.3 mg kg(-1) expressed in lipid basis for both bound 3- and 2-MCPD and 0.6 mg kg(-1) expressed in lipid basis for bound glycidol. A blank spiked with 3-monochloropropanediols fatty acid esters (MCPDE) and 2-MCPDE (0.3, 2.1, and 7.2 mg kg(-1)) and glycidol esters (0.6, 4.7, and 16.6 mg kg(-1)) were chosen for accuracy and precision tests. The recoveries were 91.7% to 105.9%. Both repeatability and within-laboratory reproducibility of the analysis were within the acceptable level of precision ranging from 1.7% to 16%. This is the first time that a full validation procedure extending to both accuracy and precision tests has been carried out for sweetened creamer and chocolate spread. Overall, the combined protocol of ASE and AOCS Cd29a-13 was successfully validated for both solid and liquid food samples with lipid content from 10% to 30%.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 2915-53-9. Safety of Dioctyl maleate.
