Wong Road, Guangzhou Chemical Co., Ltd. in the new century, the booming Wang Lu Da Company invites you to common development, and work together for the development of the chemical industry, contribute to the social and economic prosperity, to achieve brand and market dream! Main: ethylene glycol, diethylene glycol, isopropyl alcohol, cleaning agents, DOP, xylene and other solvents. Transparent colorless liquid. Special smell aromatic. Department from 45% to 70% of m-xylene, 15% to 25% p-xylene and 10% to 15% ortho-xylene composed of three isomers and mixtures thereof. Easy flow. With ethanol, ether and many other organic solvents, almost insoluble in water. The relative density of about 0.86. Boiling point of 137 ~ 140 ℃. Refractive index (n? 20D) 1.4970. A flash point of 29 ℃. Flammable vapor can form explosive mixtures with air, the explosion limit is about (by volume) of 1% to 7%. Slightly toxic, LC50 (rat, inhalation) 0.6 7% / 4h. Irritation. A narcotic at high concentrations of vapor. Guangzhou Wong Road, Chemical Co., strength, credit, guarantee quality bottled xylene, 99.9% more than high-quality varieties of high purity xylene operating characteristics of Dongguan industrial barrels xylene, 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 ℃ Dongguan industrial barrels xylene, it can not be used distillation separation Dongguan industrial barrels xylene, current methods of research and development at home and abroad is a low-temperature crystal separation; separation and adsorption 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, paraxylene by eutectic limit Dongguan industrial barrels xylene, 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. Bottled solvent xylene _ Wong Road Chemical (Online) _ Bottled xylene from the busy road in Dongguan, Guangzhou Chemical Co., Ltd. to provide. Guangzhou Wong Road, Chemical Co., Ltd. (www.wangluda.com) (www.wangluda.com) is a leader in Guangzhou, cosmetic raw materials, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
