    摘要: PURPOSE:To obtain a high quality azobisamide-oxide in high yield in a short time by carrying out the reaction of an azobisalkylnitrile with a hydroxylamine in dimethylsulfoxide and/or N-methyl-2-pyrrolidone as a reaction solvent. CONSTITUTION:Dimethyl sulfoxide and/or N-methyl-2-pyrrolidone are used as reaction solvents to effect the reaction of an azobisalkylnitrile of formula I (R and R are each a 1-4C alkyl or they form together a 3-6C cycloalkyl) with hydroxylamine to give an azobisamide-oxime of formula II. The azobisamide-oxime is useful as a polymerization initiator or a foaming agent. The use of the high quality azobisamide-oxime produced by this process is safe because it does not contain toxic mononitrile. This compound does not need further purification in the case to obtain a polymer bearing amide-oxime terminal groups in high efficiency.
