Adopt a new process method for extracting products, after acetone and acrylonitrile generate diacetone acrylamide in concentrated sulfuric acid, the extraction of the product does not need to go through recrystallization, avoiding the pollution of volatile solvents to the environment; using orthogonal test design The three main factors affecting the extraction process (extraction water consumption, the amount of alkali solution used in the alkali washing process, and the alkali washing time) were optimized by using the method, and the product yield was 54.5%, and the melting point was 53-56 °C. A cross-linked acrylate emulsion was prepared using hydrazine as a cross-linking agent, and the cross-linking reaction was confirmed by infrared spectroscopy, and the film properties of the cross-linked emulsion were studied.
