- 用途一:用作液晶原料及中间体,也用于生产农药
- 上游原料:三氯化铝 --> 乙酰氯 --> 氧 --> 三氯乙醛 --> 乙基苯 --> 2,2,2-三氯乙醇
- Sigma Aldrich:619-64-7(sigmaaldrich)
- 方法一:其制备方法是在反应釜中加入乙基苯和三氯乙醛,在0℃分批加入无水三氯化铝,加毕后在-10~0℃搅拌反应2h,然后加入稀盐酸至混合液中分解其剩余三氯化铝,再用NaHCO 3 和水洗涤,有机层蒸馏回收乙基苯,再蒸馏得对乙基苯-2,2,2-三氯乙醇,然后将此三氯乙醇溶于甲醇,再加入NaOH溶液搅拌,在该混合液中,滴加30%过氧化氢水溶液,搅拌至三氯乙醇消失,然后再HCl酸化,得到结晶即产品。
