Under basic conditions, MBA reacts further with formaldehyde at the amide nitrogen to give N-hydroxymethyl,N,N′-methylenebisacrylamide.Nucleophiles such as alcohols, amines, or thiols add across the activated vinyl groups, giving mixtures of mono- and disubstituted products.
1,1,2,2-tetrachloroethane was used in large amounts to produce other chemicals like trichloroethylene, tetrachloroethylene, and 1,2-dichloroethylene. [ 6 ] Because of its possible carcinogen effects on humans, the production of 1,1,2,2-tetrachloroethane has decreased significantly and is no longer widely used as an end-product. [ 7 ]
