| Abstract: | 2-Butyne-1,4-diol ditoluene-p-sulphonate was synthesized via sulfonylation starting from 2-bu- tyne-1,4-diol and toluene-p-sulphonate chloride with sodium hydroxide of 25% as acid binding agent. Under the optimum reaction conditions as follows：the molar ratio of toluene-p-sulphonate chloride to NaOH to 2-butyne- 1,4-diol was 2. 6 ： 2. 4 ： 1 ,reaction temperature was 0 ℃, reaction time was 6 h,the yield of 2-butyne-1,4-diol ditolu- ene-p-sulphonate was 94.1%. The structure of product was confirmed by elemental annlysis, IR and 1 HNMR. |
