Guangzhou Wong Road, Chemical Co., Ltd. is a manufacturer of industrial-grade ethylene glycol, ethylene glycol mainly engaged in imported green polyester grade ethylene glycol manufacturers special wholesale, oil grade ethylene glycol. Antifreeze is dedicated 99.9% high purity ethylene and other chemical raw materials. Professional production factory direct, spot ethylene supply stability, quality assurance; price advantage, the cash supply. Domestic ethylene production process: synthesis gas line method based on the process after coal or natural gas as raw material, synthesis gas obtained by direct synthesis or indirect synthesis of ethylene glycol is made final. At present, the production of synthesis gas line method glycol devices are used indirect method. Indirect method of practical application of oxalate. That is the first to obtain coal synthesis gas, and then generate dimethyl oxalate (DMO) catalyzed reaction, and then Cu / Cr as a catalyst for the next 150 ℃ condition DMO low-pressure hydrogenation of ethylene glycol taken. The method conversion rate of 99.8%, 99.9% high-purity ethylene glycol, ethylene glycol selectivity of 95.3%. Fujian Institute of Research on the Structure of the development of coal-to-glycol technology was industrialized in 2009, and in 2012 the successful output of polymer grade ethylene glycol manufacturer in Shenzhen, marking China's coal-to-B diol made a major breakthrough. But part of the device is currently running load also failed to meet the design level, the stability of the catalyst is also subject to further verify the actual production of industrial glycol (ethylene glycol), also known as "glycol", "1, ethylene glycol antifreeze special Manufacturers, 2-ethylene glycol ", referred to EG. Formula (HOCH2) ?, is the easiest glycol. Ethylene glycol is a colorless, odorless, sweet liquid, toxic to animals, human lethal dose of about 1.6 g / kg. Ethylene glycol with water, acetone solubility, but is less soluble in ethers. Used as a solvent, antifreeze, polyester and synthetic materials. Polymers of ethylene glycol polyethylene glycol (PEG) is a phase transfer catalyst, but also for cell fusion; which nitrate is an explosive.
