and asymmetrical quaternary ammonium chlorides of the general formula R1R2R3N+AR4Cl– (R1 = Me, Bu; R2 = n-C12H25, PhCH2, CnH2n+1(OCH2CH2)m, n = 9 and 12, m = 1 and 2; R3 = n-C12H25, PhCH2, HOCH2CH2,–OOCCH2; R4 = n-C12H25, PhCH2; A = (CH2CH2O)1,2, CH2C(O)O) was synthesized by the alkylation of tertiary amines in a two-phase system containing water. A convenient method for the synthesis of the initial
通式R1R2R3N+AR4Cl–(R1 = Me, Bu; R2 = n-C12H25, PhCH2, CnH2n+1(OCH2CH2)m, n = 9 and 12, m = 1)的一系列无环对称和不对称季铵氯化物和 2; R3 = n-C12H25, PhCH2, HOCH2CH2,–OOCCH2; R4 = n-C12H25, PhCH2; A = (CH2CH2O)1,2, CH2C(O)O) 是通过叔胺的烷基化合成的相系统含水。一种合成通式 MeNR1R2 的初始对称和不对称叔胺的简便方法(R1 = Me, Bu;R2 = n-C12H25, PhCH2, CnH2n+1(OCH2CH2)m, n = 9 和 12, m = 1 和 2) 在有机相-水相非均相系统中被开发出来,它允许使用碱和胺的水溶液。
