The Effect of Various Factors on Hydrolysis of Thiophosphate
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 12
Abstract
The nucleophilic hydrolytic reactions of Mono-isobutyl phosphate ester & Mono-2,4,6 tribromo thiophosphate ester have been discussed in this paper. Study of the hydrolysis of these monoesters have been made in the region .1 to 8 mol dm-3 HCl acid & pH 1.24 to 7.46 at 650C & 500C respectively. Detailed study of the hydrolysis has been made at constant ionic strength, temperature, effect of solvent & concentration etc.The concept such as Hammatt acidity function1, Bunnet Parameters2, Zucker-Hammett hypothesis, isokinetic relationship3etc. have been applied to determine the probable reactions. It is clear from the experiment that the reactivity of monoesters is more than di- & tri- esters but di-negative sps. of monoester have very less contribution to the overall rate of hydrolysis.
