Fagge, Ibrahim I.; Ahmad, W. Hamdah W.; Zain, Sharifuddin Md; Khan, M. Niyaz published an article in 2018, the title of the article was Kinetics and mechanism of counterionic salt-catalysed piperidinolysis of anionic phenyl salicylate in the presence of cationic-nonionic mixed micelles.Application In Synthesis of Phenyl Salicylate And the article contains the following content:
The quant. correlation of counterion-affinity to aqueous hexadecyltrimethylammonium bromide (HDAB, cationic micelles/nanoparticles) and the counterion-induced HDAB micellar growth, in the presence of different amounts of poly(ethylene glycol hexadecyl ether) (C16E20, nonionic surfactant), was achieved by the use of a semi-empirical kinetic (SEK) method. The values of the ratio of cationic HDAB, as well as mixed HDAB-C16E20, micellar binding constants of X and Br, KX/KBr (= KBrX or RBrX) for X = 4-ClC6H4CO2-, were obtained by the SEK method. The concentration range (0.006-0.015 M) of pure HDAB was found to have no influence on the values of KBrX or RBrX. These observations were also recorded upon addition of a nonionic surfactant, C16E20, in an aqueous solution of HDAB. The mean value of KBrX or RBrX obtained in the presence of pure HDAB (KBrX or RBrX = 50.3) is 2.3 times larger than that in the presence of mixed HDAB-C16E20 (mKBrX or mRBrX = 21.7). From rheometric measurements of aqueous HAD+/4-ClC6H4CO2- with 0.015 M HDAB, single sym. maxima (at both 25 and 35 °C) were obtained at [4-ClC6H4CO2Na] = 0.03 M. This is evidence for the existence of wormlike micelles/nanoparticles. However, the absence of a maximum in rheometric data for aqueous HAD+/C16E20/4-ClC6H4CO2- with 0.015 M HDAB and 0.006 M C16E20 at various [4-ClC6H4CO2Na] revealed the existence of spherical micelles. The experimental process involved the reaction of Phenyl Salicylate(cas: 118-55-8).Application In Synthesis of Phenyl Salicylate
