METHOD FOR ISOLATION OF 1,2-DICHLOROETHANE Russian patent published in 1994 - IPC

Abstract RU 2009115 C1

FIELD: chemical technology. SUBSTANCE: preliminary polycondensation of heavy chlororganic products of vat residue together with petroleum slime is carried out by acid catalyst. Unreacted 1,2-dichloroethane is isolated by distillation. Petroleum slime is waste of high temperature homogeneous pyrolysis of light petroleum products. Acid catalyst is prepared of waste sulfuric acid. Isolation degree of 1,2-dichloroethane by cooperative utilization of wastes is 91-98% . EFFECT: improves efficiency of the method. 1 dwg, 1 tbl
