METHOD FOR PREPARING AMIDE

The present invention provides a method for preparing amides, in which an amino acid ionic liquid is used as both a reaction medium and a catalyst to catalyze Beckman rearrangement of a ketoxime, so as to produce an amide. In the method, the rearrangement is conducted by catalyzing a ketoxime with an amino acid ionic liquid having the asymmetric property at a moderate reaction temperature during a short reaction time, so as to produce an amide without adding other catalysts such as concentrate sulfuric acid. The method has advantages such as avoiding corrosion in equipments with pipelines, the high conversion rate of ketoximes and the high selectivity of amides.

Zwitterionic monomer having amino-multicarboxylic acid functionality

A zwitterionic monomer having amino-multicarboxylic acid functionality having Structure (I) wherein R1is selected from the group consisting of H, an alkyl group having 1 to 6 carbon atoms; R2is (CH2)nwhere n is 2 to 12; R3and R4are independently an alkyl group having 1 to 6 carbon atoms; R5is (CH2)mwhere m is 2 or 3; R6and R7are independently selected from wherein R20is selected from the group consisting of H, CH3, and COOY; R21is selected from H or CH3; X is oxygen or nitrogen; A is a halide; and Y is independently a cation. The zwitterionic monomer is the reaction product of an amino-multicarboxylic acid and an amine containing monomer. Polymers prepared with the zwitterionic monomer are especially useful in hair treatment compositions to provide increased stiffness to hair, in coating formulations to increase the impact resistance, wet adhesion, and flexibility of the coating, especially wood coatings, and in mortar compositions to improve mortar compatibility, especially with redispersible powders.
