Description

Поэтому такие побочные продукты сжигаютс  с образованием хлористого водорода м углекислого газа.The currently existing production of chlorolefins and chloroalkanes practically do not provide for the qualified use of the by-products formed during the process, such as tertiary butyl chloride in the production of metal chloride and chlornropenes in the production of allyl chloride, the amount of which is 0.1-0.3 t / t product. Therefore, such by-products are burned to form hydrogen chloride and carbon dioxide.

Учитыва  все возрастающий дефицит углеводородного сырь , переработка крупнотоннажных отходов хлорорганических продуктов в углекислоту представл етс  крайне нерациональной, поскольку св зана с потерей углеводородной части отходов.Taking into account the growing shortage of hydrocarbon raw materials, the processing of large-tonnage organochlorine wastes into carbon dioxide is highly inefficient, since it is associated with the loss of the hydrocarbon portion of the waste.
