CATALYTIC METHOD OF PRODUCING (METH)ACRYLATES OF N-HYDROXYALKYLATED AMIDES Russian patent published in 2011 - IPC C07D233/32 C12N9/16 C08F20/06 

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing (meth)acrylates of N-hydroxy-alkylated amides, in which cyclic N-hydroxyalkylated amides (C): , where Z¹ denotes unsubstituted or mono-substituted nitrogen (N-R³); R¹ and R², in each case independently denote an alkylene with 2-20 carbon atoms, cycloalkylene with 5-12 carbon atoms, arydene with 6-12 carbon atoms; R³ denotes hydrogen, alkyl with 1-18 carbon atoms, alkenyl with 2-18 carbon atoms, aryl with 6-12 carbon atoms or cycloalkyl with 5-12 carbon atoms; etherified with methacrylic acid or reesterified with at least one (meth)acrylic ester (D) in the presence of at least one heterogeneous catalyst selected from a group consisting of inorganic salts (Co), having pKb not higher than 7.0 and not lower than 1.0, and its solubility in the reaction medium at 25°C is not more than 1 g/l, and enzymes (F) selected from a group comprising esterase (E.C.3.1.-.-), lipase (E.C.3.1.1.3), glycosylase (E.C.3.2. -.-) and protease (E.C.3.4. -.-), where the heterogeneous catalyst is separated from the reaction mixture through filtration, electrofiltration, absorption, centrifuging or decantation.

EFFECT: efficient method of producing (meth)acrylates of N-hydroxyalkylated amides.
