| Abstract: | The technological conditions for synthesized of 3-chloro-2-hydroxypropyl trimethyl ammo- nium chloride from trimethylamine hydrochloride and epichlorohydrin in the alcohol-water media was studied. The optimum reaction conditions were obtained by orthogonal experiments as follows: pH of reaction liquid 89; reaction temperature 35 ℃;n(epichlorohydrin)/n(trimethylamine hydrochloride)=0.95∶1; reaction time 1 h. The yield was 91%. |
