3-CHLORO-3-METHYL-1-BUTYNE - Preparation
1000kg 3-methylbutyne -3-alcohol is put into 275 kg of 36% hydrochloric acid (chlorination kettle), 10kg of cuprous chloride is added, then 1200 kg of isophthalic acid and 1440 kg of trichloromethyl benzene are put into the acylation kettle and heated to 70-85 ℃, 1.5kg of ferric chloride is put into it, 1440 kg of trichloromethyl benzene is added dropwise after. During the period, the refrigerant setting temperature is -20 ℃, the hydrochloric acid in the hydrochloric acid washing tower is purchased concentrated hydrochloric acid with a concentration of 30%, and the washing liquid temperature during the washing process is 40~45 ℃. The purity of benzoic acid recovered from hydrochloric acid washing solution is 97.32%, and the purity of 3-chloro-3-methylbutyne finally obtained is 94.57%, and the yield is 96.28%.
