A METHOD OF TREATMENT OF HALOGENOUS, ORGANIC WASTE MATERIAL

摘要

Halogenous, organic waste material such as PVC is subjected to a hydrolysis treatment by suspending 1 part by weight of the waste material in comminuted state in 1-10 parts by weight of water in the presence of a base and heating this to a temperature of between 250-280� C. at a pressure sufficient to maintain the water in liquid state for a period of time sufficient to convert substantially all organically bound halogen present to inorganic halides. By the treatment valuable halogen-free organic compounds are generated as decomposition products ensuring the economy of the treatment.
