摘　　要：在相转移催化剂作用下,2-氯-1,1,1,4,4,4-六氟-2-丁烯(HCFO-1326mxz)在碱液中脱氯化氢合成六氟-2-丁炔。研究表明,以四丁基氯化铵(摩尔分数2%)为相转移催化剂,反应温度为40℃、HCFO-1326mxz与氢氧化钠摩尔比为1∶4、反应时间为6 h,HCFO-1326mxz转化率为96.3%,六氟-2-丁炔选择性为91.4%。Hexafluoro-2-butyne was synthesized by dehydrochlorination of 2-chloro-1,1,1,4,4,4-hexafluoro-2-butene(HCFO-1326mxz)in alkaline solution under the action of phase transfer catalyst.The results showed that using tetrabutylammonium chloride(mole fraction 2%)as phase transfer catalyst,the reaction temperature was 40℃,the molar ratio of HCFO-1326mxz and sodium hydroxide was 1∶4,the reaction time was 6 h,the conversion of HCFO-1326mxz was 96.3%,and the selectivity of hexafluoro-2-butyne was 91.4%.
