Production Method Editor 1, xylene recovered from the coking by-product. Xylene, benzene co-product is produced, 99.9% technical grade xylene, according to the different boiling points of the components of crude benzene, distillation fraction extracted with boiling range of 135 ~ 145 ℃ obtain xylene. 2, light gasoline platinum reforming method using atmospheric distillation (initial boiling point of about 138 ℃), interception fraction greater than 65 ℃, the first by molybdenum catalyst, catalytic hydrogenation emerge harmful impurities, and then platinum catalyst to revitalize, with diethylene glycol ether solvent extraction, and then by the distillation tower, benzene, toluene, xylene and other products. 3, toluene disproportionation method. This method is in the catalyst, so that a toluene methyl transfer to another toluene to produce benzene and xylene. The reaction is DF-166 catalyst (lack of aluminum-hydrogen mordenite), Foshan industrial grade xylene, toluene to restructure (nitration grade) and re-circulation of hydrogen (85% -90%) as a raw material, how much industrial grade xylene By money, the reaction temperature 400 ± 2 ℃, the pressure is about 2MPa other conditions, the reaction of benzene and xylene. 4, the oil light fraction after mixing benzene hydrogenation refining, catalytic reforming, separation derived xylene. Or coking crude benzol washing, fractionation derived. Guangzhou Wong Road, Chemical Co., strength, credit, guarantee quality bottled xylene, 99.9% more than high-quality varieties of high purity xylene operating characteristics, has won the trust of our customers. After several years of development, high-purity industrial grade xylene, Wang Lu Da Company has established long-term stable cooperative relationship with many well-known solvents, industrial, xylene isomerization stage raw material supplier, it is more than excellent grade, brand xylene international chemical company in China designated dealers. Xylene contact First-aid measures Skin contact: Remove contaminated clothing, use soap and water thoroughly washed skin. Eye contact: Did eyelid, with the flowing water or saline. Medical treatment. Inhalation: rapidly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately. Medical treatment. Ingestion: drink enough water, the symptoms. Medical treatment. Bottled xylene leaked fighting measures hazardous characteristics: flammable vapor and air can form explosive mixtures case of fire, high-heat combustion caused the explosion. It can react with oxidants. Velocity too fast, easy and accumulation of static electricity. Its vapor is heavier than air, will spread to the lower Department of considerable local, fire source will fire back. Hazardous combustion products: carbon monoxide, carbon dioxide. Fire fighting methods: water cooling containers, if possible to move containers from the scene empty Department. Extinguishing Media: Foam, carbon dioxide, dry, sandy soil. Where there is industrial grade xylene Sell | Foshan industrial grade xylene | Wong Road Chemical provided by the Guangzhou City Mong Road to Chemical Co., Guangzhou Wong Road, Chemical Co., Ltd. (www.wangluda.com) (www.wangluda.com) strong, credible, in Guangzhou cosmetic raw materials industry has accumulated a large number of loyal customers.
