摘要: 反式-1-氯-3,3,3-三氟丙烯[HCFO-1233zd(E)]的臭氧消耗潜值(ODP)为0.00024,温室效应潜值(GWP)为7.0,环保性能优良,已被国际社会认定为第四代氟代烃发泡剂,应用前景广阔。本文对现有HCFO-1233zd(E)制备方法进行综述,通过比较各合成路线优缺点,提出以HCC-240fa及其衍生物为原料的合成路线最具工业化前景。同时,对制备工艺中涉及的HCFO-1233zd(E)与HF和副产物共沸分离问题进行了分析总结。最后指出高效的氟化催化剂和绿色的分离工艺是未来HCFO-1233zd(E)工业化开发的研究重点。

Abstract: Trans-1-chloro-3,3,3-trifluoropropene[HCFO-1233zd(E)] has virtually zero ozone depletion potential(ODP,0.00024)and very low global warming potential(GWP,7),and therefore it has been proposed as the fourth-generation blowing agent to replace 1,1-dichloro-1-fluoroethane(HCFC-141b)and 1,1,1,3,3-pentafluoropropane(HFC-245fa),due to its very low impact for environment. Synthetic methods of HCFO-1233zd(E) were summarized according to the starting materials. Compared with other routes,the process using HCC-240fa and its derivatives as starting material features good yield and excellent selectivity,and thus has an industrialization prospect. Moreover,the azeotropic separation of HCFO-1233zd(E) with HF and by-product in the preparation process was analyzed and summarized. Developing efficient fluorination catalyst and environmentally friendly purification technology is fundamentally important for industrial synthesis of HCFO-1233zd(E).

Key words: trans-1-chloro-3,3,3-trifluoropropene[HCFO-1233zd(E)], blowing agent, synthesis, separation
