Guangzhou Wong Road, Chemical Co., Ltd. production and supply of high content of bottled xylene, xylene and other thinner spot, in a variety of 99.9% high purity solvent grade xylene operating characteristics, has won the trust of our customers. Solvent, industrial, wholesale xylene isomerization level of imports of high-quality, and production suppliers to establish a long-term stable cooperative relations, direct marketing xylene chemical raw materials manufacturer. High purity xylene respiratory protection: concentration in air overweight, wearing a gas mask filter type (half-mask). Emergency rescue or evacuation, it is recommended to wear air respirators. Eye protection: Wear protective chemical safety glasses. Physical protection: wear protective overalls on infiltration. Hand protection: Wear rubber gloves. Other protection: work site prohibit smoking, eating and drinking. After work, take a shower. To maintain good health habits. Physical and chemical properties xylene main components: the content of ≥96%. Appearance: colorless, transparent liquid, similar to the smell of toluene. Melting point (℃): -25.5 Boiling point (℃): 144.4 Relative density (water = 1): 0.88 Relative vapor density (air = 1): 3.66 saturated vapor pressure (kPa): 1.33 (32 ℃) heat of combustion (kJ / mol ): 4563.3 critical temperature (℃): 357.2 critical pressure (MPa): 3.70 Production Method Editor 1, the coking by-product recovery xylene. Xylene and benzene production co-products, industrial grade xylene isomers, depending on the boiling point of the components of crude benzene, xylene brand industry, extracted by distillation fraction boiling range of 135 ~ 145 ℃, was 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, we are professional manufacturer of chemical raw materials, catalytic hydrogenation emerge harmful impurities, Dongguan industrial xylene, and then a platinum reforming catalyst, solvent extraction with diethyl ether glycol, and then the distillation tower to obtain as benzene, toluene, xylene and the like 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) to restructure toluene (nitration grade) and re-circulation of hydrogen (85% to 90%) for raw materials, the reaction temperature is 400 ± 2 ℃, the pressure is about 2MPa Under 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. Dongguan industrial xylene | Wong Road Chemical | Premium grade industrial xylene by the Wong Road, Guangzhou Chemical Co., Ltd. to provide. Dongguan industrial xylene | Wong Road Chemical | Premium grade industrial xylene is Guangzhou Wong Road, Chemical Co., Ltd.
