Paragraph 0010, (2017/03/17)
The invention discloses a synthetic process a synthetic process for 3-dodecyloxy-2-hydroxypropyltrimethyl ammonium chloride. The synthetic process provided by the invention is simple and has high yield. The process comprises the following steps: 1, synthesis of dodecyloxy glycidol ether: a step of adding 18 to 25 g of laurinol, 18 to 24 g of chloropropylene oxide, 13 to 15 g of an aqueous sodium hydroxide solution with a mass percentage of 40%, 1.5 to 2.5 g of tetrabutylammonium bromide and 10 to 20 ml of toluene into a dry three-neck flask and carrying out a stirring reaction at 50 to 70 DEG C for 4 to 6 h; and 2, synthesis of DPAC: a step of adding 8 to 10 g of laurinol, 9 to 12 g of trimethylamine hydrochloride and 10 to 30 ml of ethanol into a dry three-neck flask and carrying out a stirring reaction at 30 to 50 DEG C for 3 to 4 h.
