Method of producing a highly reactive pitch fraction and its usage |
摘要 |
A method of producing a highly reactive pitch fraction is disclosed. Coal-tar pitch is extracted with hot chloroform and the pitch solution treated with solid iodine. The solid reaction products are separated and, in the presence of chloroform, decomposed with an aqueous ammonia solution. Following separation of the aqueous phase and removal by distillation of the chloroform, there remains a highly reactive pitch fraction which can be converted into high-anisotropic carbon at low temperatures and in short coking times.
