Reaction Steps
In Chemical Abstracts 91:158321U acetone cyanohydrin is reacted in aqueous solution with more than 1 mole sulphuric acid to form acrylamide sulphate in the presence of unreacted sulphuric acid, and further water is added and the mixture hydrolysed to form methacrylic acid. In Chemical Abstracts 83:44010W a similar process is described starting from methacrylonitrile, with the final product being subjected to phase separation and recycling of the small amount of distillate.
