IMPROVED CATALYSTTFREE MANUFACTURE OF NN*TERTIARY AMINOALKYL*ACRYLAMIDE

摘要

A non-catalytic process for the preparation of N- (tertiaryaminoalkyl) acrylamides is disclosed which comprises subjecting a corresponding &bgr; -aminopropionamide to a pyrolysis temperature of about 180° to 300. degree. C. after storage of the &bgr;- aminopropionamide in an atmospheric holding tank at a temperature of about 150° to 220. degree. C. from eight to seventy-two hours prior to pyrolysis. The corresponding &bgr;-aminopropionamide compounds can be prepared by mixing and reacting at least two moles of a tertiaryaminoalkyl amine with an acrylic acid or ester compound. The inventive process provides the production of the N-(tertiaryaminoalkyl) acrylamides in high yields with minimal back addition or polymerization and greatly reduced acid impurity levels.
