合成研究方面,浙江化工研究所设计了一套全流程试验装置,通过试车对工艺流程进行了探索,并为催化剂的评选及条件试验打好基础。采用聚四氟乙烯锥管电远传流量计解决了氢氟酸计量问题,同时采用自力式稳压装置解决了三种原料气的输送问题;进行了十五种催化剂的评选,找出较好的催化剂,最高收率为70.2％,平均收率40—45％, In terms of synthesis research, Zhejiang Chemical Engineering Research Institute has designed a set of full-flow test device, explored the technological process through trial run, and laid the foundation for catalyst selection and condition test. Adopting Teflon telemeter to solve the measurement problem of hydrofluoric acid, the problem of transportation of three kinds of raw material gas was solved by self-operated voltage regulator; the selection of fifteen kinds of catalysts was carried out to find out better Of the catalyst, the highest yield of 70.2%, the average yield of 40-45%
