The esters of 0 (2,6-dichlorophenylamino) phenylacetic acid have the general formula Ib means R - OH and n assumes values from 10 to 450, with a molecular weight from 700 to 30,000, determined by the vapor pressure method.n n n These esters are obtained by reacting 0 (2,6-dichlorophenylamino) phenylacetic acid with polyethylene glycol of the general formula HO (CH-CHO) n H, in which n assumes values of 10-450, in the presence of acid in a medium of an inert solvent, made with heating.n n n These esters are biologically active substances and are used in medicine. |
