Embodiment 1-10
[0029] Embodiment 1-10 relates to a production process of trans-1,2-dichloroethylene, specifically comprising the following steps:
[0030] S1: add barium chloride catalyst into 100ml tetrachloroethane solvent;
[0031] S2: heating the reaction system;
[0032] S3: Under the condition of condensing and refluxing, acetylene and chlorine gas are continuously passed into the solvent for 2 hours. See Table 1 for the feeding speed, catalyst consumption, reaction temperature and reaction pressure of each implemented acetylene and chlorine.
