  • Patent number: 4251461
    Abstract: A non-catalytic process for the preparation of N-(tertiaryaminoalkyl)acrylamides is disclosed which comprises subjecting a corresponding .beta.-aminopropionamide to a pyrolysis temperature of about 180.degree. to 300.degree. C. after storage of the .beta.-aminopropionamide in an atmospheric holding tank at a temperature of about 150.degree. to 220.degree. C. from eight to seventy-two hours prior to pyrolysis. The corresponding .beta.-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.
