| Abstract: | With L-Ethyl lactate acid, it was acylated to give L-Ethyl p-toluenesulfonyl lactate. And reacted with hydroquinone, R-(+)-2-(4-Hydroxyphenoxy) propyonic ester was gotten. We process the conditional test of catalyst, reaction temperature and time, molar ratio to reactants, solcent usage, the amounts of alkali, and explore a best technical condition. The yield was up to 90% and the structures of these compounds were identified by using IR and MS spectrum. |
