| titleOfInvention | New process for preparing cationic surfactants having lactam rings |
| abstract | In the first step, the lactone is reacted with ω- (N, N-dialkylamino) alkyl amine to prepare ω- (N, N-dialkylamino) alkyl lactam of the following general formula (I) In the second step, the dialkyl lactam prepared above is reacted with an alkyl halide in the presence of water or a solvent of monovalent, divalent, trivalent or polyhydric alcohols to form the quaternized lactam derivative of the following general formula (II) It relates to a method of manufacturing.n n n n n n n n In the above formula,n n n R 1 , R 2 and R 3 are alkyl groups having 1-20 carbon atoms,n n n m is 2-10,n n n n is 1-6,n n n X is chloride or bromide. |
