FIELD: organic synthesis. SUBSTANCE: method is carried out by dehydrogenation of 1,1,2-dichloroethane, the process takes place at atmospheric pressure and at 200-280 C in the presence of heterogeneous catalyst. Proposed catalyst comprises $$$ and $$$ as a base. Concentration of 1,1,2-trichloroethane in nitrogen is $$$ mol/l, its volume rate being 70-700 $$$. Yield of cis-1,2-dichloroethane and trans-1,2-dichloroethane is 33.0-65.5 mol % and 19.3-32.4 mol %, respectively. EFFECT: improved efficiency of the method. 5 tbl |
