Abstract
PURPOSE: A crude product obtained as an aqueous solution, resulting from the reaction of the starting mixture by heating and hydrolysis, is washed with such an organic solvent that it does not dissolve the product and is insoluble in water to produce the titled substance used a polymerization component of photosensitive resins and adhesives inexpensively in high yield.
CONSTITUTION: Acetone or diacetone alcohol, acrylonitrile and sulfuric acid are heated to effect reaction, the product is hydrolyzed, neutralized, diluted to give a crude product of N-(1,1-dimethyl-3-oxobutyl)acrylamide as an aqueous solution. The solution, without extraction with an organic solvent, is washed with a nonsolvent that does not dissolve the product and is inmiscible with water such as hexane or petroleum ether to effect purification. The reaction mixture, after neutralization before dilution with water, or after washing and concentration, is heated together with an alkali aqueous solution to remove acrylamide formed as a by-product by hydrolysis.
