Product Applications

Widely used as raw materials for organic solvents and synthetic medicine, paint, resin, dye, explosive and pesticide, etc.; Used as cleaning agent; Mixed xylene is a mixture of O-, m-, p-xylene and ethyl benzene. When used as a chemical raw material, each isomer can be separated in advance. The mixture is mainly used as oil..

Production method

1. Coking by-product recovery benzene high-temperature coking by-product High-temperature tar contains part of benzene. First, through the initial distillation column, light benzene is obtained at the top of the column and heavy benzene is obtained at the bottom of the column (heavy benzene is used as the raw material for preparing kumalong resin). Light benzene is separated by the primary distillation column first, and the mixed fraction at the bottom of the column is washed by acid and alkali to remove impurities, then it is steamed and blown into the benzene column, and then it is rectified by the distillation column to obtain pure benzene. 2. The platinum reforming method uses Benzine obtained by atmospheric distillation (the initial distillation point is about 138 ℃), intercepts the fraction greater than 65 ℃, first removes harmful impurities through molybdenum-containing catalyst, then carries out reforming through platinum catalyst, solvent extraction with diethylene glycol ether, and then distillation by Tower to obtain benzene; Toluene; Xylene and other products.
