Abstract

Recently, due to the increasing environmental problems in the process of industrial chemical production, there is a need to increase the conversion of raw materials into the finished products. This prevents the formation of by-products and especially toxic waste. This dramatically reduces the cost for selection and utilization toxic industrial waste. In this paper we describe a several  of new policy decisions more effective ways of processing and recycling of industrial organochlorine waste (OCW) in the production of dichloroethane and vinyl chloride monomer, returning — recycling of raw materials.

The study on chlorination of unsaturated chlorinated wastes showed that the additional treatment with chlorine to reduce the amount of unsaturated OCW and to increase the content of 1,2-dichloroethane in chlororganic waste at 9-15% reduced the loss of 1,2-dichloroethane when burned. The study optimized the conditions of the process of alkali dehydrochlorination, using a freshly prepared suspension of Ca(OH)2 in NaOH, which allows to process the 1,2-dichloroethane and 1,1,2-trichloroethane with a total conversion of 95-96% of trade vinyl chloride and vinylidene chloride  to the outputs of the last 25-70%. This method can reduce the amount of waste incinerated chlororganic 2-5 times.
