PROCESS FOR PREPARATION OF AMIDES AND ESTERS OF 2-((2-HYDROXYPROPANOYL)OXY)PROPANOIC ACID
Original language description
The present invention describes method of preparation of amides of lactyl lactates of general formula I, where Z denotes to group of RR'—N and R represent alkyl, aryl or H from lactide and the lactide reacts with an aliphatic or aromatic amine with 1 to 100 carbon atoms of general formula RR'NH or with an aliphatic or aromatic ammonium hydrohalide with 1 to 100 carbon atoms of general formula RR'NH·HX, where X is selected from Cl, Br and I in a non-chlorinated organic aliphatic or aromatic solvent or in amelted mixture of lactide under solvent free condition, and when lactide reacts with amine, initiator derived from group of Lewis acids of halides of 4., 12., 13., and 14. group is added.
