PROCEDEU DE OBTINERE A N-TERBUTILFORMAMIDEI PURE

摘要

N-alkyl formamides or the corresponding N-cycloalkyl or N-aralkyl formamaides are prepared by reacting olefins, cycloolefins or aralkenes with hydrogen cyanide in the Ritter reaction using about 2.5 moles of acid per mole of olefin at a temperature of 30 DEG to 70 DEG C. and the unneutralized acid reaction mixture is extracted with acid stable polar solvents and the extract is worked up in conventional manner.
