Abstract:
Provided herein is a method for producing polyaspartic acid under reflux cooling. Further provided herein are compositions including polyaspartic acid obtainable through the method. Also provided herein is a use of polyaspartic acids obtainable through the method in dishwashing agents, detergents, and cleaning agents.

Claim (Index 1):
A method for producing polyaspartic acid, the method comprising:\n (a) contacting a mixture of:\n (i) aspartic acid, and \n (ii) 1 to 25 mol % of an acidic catalyst; \n in a reactor; \n (b) heating the mixture according to (a) under reflux cooling without distillative removal of water at a reaction temperature of 100 to 220\u00b0 C. up to a degree of conversion of the aspartic acid of at least 1%; (c) polycondensing the reaction mixture according to (b) with simultaneous distillative removal of water at 170 to 250\u00b0 C. to produce polycondensates; and (d) hydrolyzing the polycondensates according to (c) with addition of a base.
