1.
Octadecyl hydroxysulfobetaine was synthesized under reaction temperature 90 ℃ and reaction time 4 h using isopropanol aqueous solution(volume ratio of isopropanol to water 2∶1) as solvent,from octadecyl tertiary amine and sodium 3-chloro-2-hydroxy propane sulfonate which was prepared using sodium hydrogen sulfite as sulfonating agent under 85 ℃.
用亚硫酸氢钠作磺化剂,在85℃下合成3-氯-2-羟基丙磺酸钠;然后以异丙醇水溶液(异丙醇与水的体积比为2∶1)为溶剂,十八烷基叔胺与3-氯-2-羟基丙磺酸钠在90℃下反应4h,合成了十八烷基羟基磺基甜菜碱,十八烷基叔胺的转化率可达97%。
6) dimethylsulfoniopropionate (DMSP)
