Patent number: 5763665Abstract: In a process for the preparation of crystalline N-methylol(meth)acrylamide from (meth)acryamide and paraformaldehyde, the reaction of the solid reactants to give a product melt and the subsequent crystallization thereof in a reactor while subjecting the reaction mixture to mechanical shear load is preferably carried out in a self-purging screw reactor or a disk reactor. The reaction of the reactants and the crystallization of the product melt are preferably carried out without added solvent. A catalyst, in particular an alkali metal carbonate or a trialkylamine, can be used for the reaction of the reactants.Type: GrantFiled: January 3, 1997Date of Patent: June 9, 1998Assignee: BASF AktiengesellschaftInventors: Kaspar Bott, Thomas Domschke, Michael Bohn
