A novel process for the preparation of hydroxyl functional esters and polyesters therefrom

A novel process for the preparation of a alkyl lactyl lactate comprising the following steps:

• a) stirring the reaction mixture of alkyl lactate, condensing reagents in anhydrous solvent at 0° C.;
• b) adding a solution of acid in solvent to a reaction mixture of step (a) slowly over a period of 1 to 3 hours;
• c) stirring the reaction mixture at temperature 27° C. for 10 to 12 hours to afford the product of monomer of alkyl lactyl lactate.
