Scope
Main technical content: This document specifies the requirements, test methods, inspection rules, marking, packaging, transportation, storage, and safety of crude benzene used in resource comprehensive utilization products. This document is applicable to the process of adiponitrile production, in which crude adiponitrile from the ammonium sulfate unit is extracted with benzene to remove organic and inorganic impurities from crude adiponitrile, and then adiponitrile is re-extracted with water to form an adiponitrile aqueous solution. After re-extraction, the crude benzene and organic impurities contain a large amount of benzene and adiponitrile. Through atmospheric distillation and vacuum distillation, crude benzene products can be obtained, which are mainly used as industrial raw materials.
