| Abstract: | The optimal technological conditions for synthesis of 3-chloro-2-hydroxypropyl -trimethylammonium chloride(CHPTMAC) were found.Thus,molar ratio of epichlorohydin to trimethylammonium chloride was 0.95,initial pH of the reaction mixture was 7.5-8.0,reaction temperature was controlled at 10 ℃ and then at 35 ℃,and suitable catalyst was added.Besides,steam distillation was applied for purifying the product.Qualified product was obtained,containing 69% CHPTMAC,with impurities epichlorohydrin≤0.0005%and 1,3-dichloro-2-propanol≤0.0015%. |
