Guangzhou Wong Road, Chemical Co., strength, quality product bottled xylene, heavy 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, Wang Lu Da Company has established long-term stable cooperative relationship with many well-known solvents, industrial, xylene isomerization stage raw material suppliers, multiple quality product, brand xylene International chemical company in China designated dealers. Xylene Preparation: Xylene, coal tar xylene, contain a considerable amount of para-xylene. Because of the inter-xylene boiling point difference is only 0.75 ℃, it can not be used distillation separation method, the current methods of research and development at home and abroad is low-temperature crystal separation; adsorption separation and complex separation. Low-temperature crystal melting point difference separation method using xylene isomer separation, the main method for the cryogenic fractional crystallization, process technology is mature, dominant in xylene separation. However, this method large equipment, barrels xylene production of direct marketing, p-xylene by eutectic limit, recovery rate is low, only 60-70%. Adsorptive separation method is a new method of development '70s, this method is less than cryogenic crystallization investment and low total cost of production, paraxylene high yield, high purity, it is possible to replace the deep cold crystallization. Guangzhou Wong Road, Chemical Co., Ltd. is a professional chemical raw materials management company, located in southern China's largest chemical distribution center - Chemical Guangzhou City.
