The main system for polyester polyester glycol, a polyester resin, a diluent, a plasticizer, a surfactant, glycol, synthetic fibers, cosmetics and explosives, and is used as solvent dyes, inks and the like, anti-formulated engine freeze agents, gas dehydrating agent. As long as the production of synthetic resin PET, fiber level PET namely polyester fiber, bottle-grade PET used to produce mineral water bottles. It can also produce alkyd resin, then surfactants, glyoxal and explosives, glycol production of direct marketing can be used as an antifreeze. 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: the process of synthesis gas line method based on coal or natural gas as raw material, ethylene glycol manufacturer, after 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 synthesis gas obtained from coal, barrels of ethylene glycol, and then by a catalytic reaction of dimethyl oxalate (DMO), then Cu / Cr as a catalyst, 150 ℃ conditions DMO low-pressure hydrogenation Preparation B diol. The method conversion rate of 99.8%, 95.3% ethylene selectivity. 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 Wong Road glycol _ _ glycol Chemical direct production by the Wong Road, Guangzhou Chemical Co., Ltd. to provide. Wong Road glycol _ _ glycol direct production of chemical Guangzhou City Mong Road, Chemical Co., Ltd. (www.wangluda.com) (www.wangluda.com) this year introduced a new upgrade, the above picture is for reference only, please call Tel or pictures on this page, for the latest information, contact: Huang Lu.
