Summary:FIELD: industrial organic synthesis. ^ SUBSTANCE: invention provides catalytic deiodination composition containing 0.95 wt parts of ethyl acetate and 8-50 wt parts of metallic zinc in the form of 3-6 mm granules. Hexafluoro-1,2,3,4-terachlorobutane production process involving use of this catalyst is characterized by that process is carried out for 20-40 h at 20-25°C, after which resulting product is washed with water at ambient temperature. Catalyst is distinguished by being accessible, inexpensive, nontoxic, and easy-to-use. Process is characterized by high yield of hexafluoro-1,2,3,4-terachlorobutane (90-98%) resulting in easiness of isolation thereof using ordinary water washing. Equipment necessities are also non-onerous. ^ EFFECT: increased yield of desired product and simplified technology. ^ 2 cl, 1 tbl, 9 ex
