Use role Editing widely used in coatings, resins, dyes, inks and other industries as solvents; used in medicine, explosives, pesticides and other industries to make synthetic monomer or solvent; can also be used as high-octane gasoline components, is an important organic chemical raw material. Can also be used to remove asphalt body. Department of Pathology mainly used tissue slices of transparency and dewaxing. Industrial raw material o-xylene was washed first with concentrated sulfuric acid to the acid layer industrial colorless, then washed with 10% sodium hydroxide solution, washed with water to pass, the aqueous layer was separated and dried over anhydrous calcium chloride, and then distillation, After the clear distillate collected in the middle fractions, namely pure product. Xylene and p-xylene mainly by crude oil priced in petrochemical manufacturing process, it is widely used thinners, printing, rubber and leather industries solvent pigments, paints and the like. As a cleaning agent and degreaser xylene, raw materials and intermediate substance an ingredient xylene aviation fuel, chemical plants, and synthetic fiber industry, paper and fabric coating and impregnating material xylene and metabolites from the breath discharged from the body very quickly, in the contact stops 18 hours almost all excreted chemical xylene, p-xylene can be very durable in the presence of drinking water. Due to the strong volatility of xylene in aqueous solution, therefore, it is not considered persistent pollutants in surface water xylene industry, Zibo xylene, Wei Wei Connaught Connaught chemical provided by Qingdao Chemical Co. Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) strong, credible, in Qingdao, Shandong chemical products industry has accumulated a large number of loyal customers.
