METHOD OF CONTINUOUS OBTAINING ALKYLAMINO(METH)ACRYLAMIDES Russian patent published in 2015 - IPC C07C231/02 C07C233/09 

Abstract RU 2546670 C2

FIELD: chemistry.

SUBSTANCE: invention relates to method of continuous obtaining alkylamino(meth)acrylamides of formula by interaction of alkyl(meth)acrylates of formula with amines of formula R2NH2 (B) in presence of catalyst. As Mixture of dioctyltin oxide and isopropyltitanate in ratio 2.5:1, which is preliminarily activated at temperature from 90 to 120°C for 2-3 hours, is used as catalyst.

EFFECT: considerable reduction of content of substance, which forms transverse bonds.
