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 oil level. 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 a catalyzed reaction of dimethyl oxalate (DMO), carried DMO low-pressure hydrogenation of ethylene producers take Jiangmen, then Cu / Cr catalyst, 150 ℃ conditions glycol. 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 industrialization was realized in 2009, and in 2012 the success of polymer-grade ethylene glycol output, marking China's coal-to-glycol achieved 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 Chinese name English name Ethylene glycol ethylene glycol nickname, EG, glycol antifreeze, MEG formula ( CH2OH) 2 molecular 62.068CAS registration number 107-21-1EINECS Accession No. 203-473-3 melting point -12.6 ℃ Boiling point 197.3 ℃ water-soluble and water-miscible Density 1.1155 (20 ℃) ??Colorless dangerous flash point 111.1 ℃ description harmful if swallowed critical pressure 7699KPa critical temperature 372 ℃℃ eccentric critical factor 0.27 molar volume 186C3 ??/ mol [1] Original glycol manufacturer | Wong Road Chemical | Qingyuan glycol provided by the manufacturer, Guangzhou Chemical Co., Ltd.
