Glycol (ethyleneglycol) at room temperature, a colorless, odorless, viscous sweet liquid. It is stable non-corrosive. Combustible but not flammable. With water, ethanol and Acetone Immiscibility. Can greatly reduce the freezing point of water. Slightly soluble in ether. Ethylene glycol is mainly used for production of polyester resin and antifreeze, in unsaturated polyester resins, Lubricants , Plasticizer , Non-ionic surface active agent in the field have little application. <<<For more exciting Click here Industry, now the only large-scale production of ethylene glycol is ethylene oxide hydrolysis. Early alcohol ethylene oxide system obtained by chlorine, but now this method has been replaced by direct oxidation, or the presence of oxygen in the air or under the conditions of ethylene by silver oxide oxidation catalyst, and ethylene oxide hydrolysis fractionation system was ethylene glycol. Industrial production of ethylene glycol in 60 years began in the 20th century. In recent years, due to the rapid growth of demand, China's ethylene production has been growing rapidly. Manufacturers are mainly distributed in China Petrochemical Corporation and China Oil The company the two companies. According to Chemical industry Online statistics, as of May 2008, China's manufacturers of ethylene glycol to 12, with a total capacity of 2.718 million tons / year. 2010 total production capacity of ethylene glycol in China will reach about 4.2 million tons. With the increase of ethylene glycol production capacity, production also increased. According to chemical-line statistics, production of ethylene glycol in China in 2008 and further increased to 1.81 million tons. In recent years, the domestic polyester industry growth by the pulling, the domestic market for rapid growth in consumption of ethylene glycol. According to chemical-line statistics, 2008, China's apparent consumption of ethylene glycol in China 700 million tons, of which about 5.2 million tons imported. Huge market gap in recent years, good prospects for the development allow the construction of ethylene glycol unit for blowing the boom. Such as Sichuan ethylene to be built in 2009, a 360,000 tons / year plant, Zhenhai Refining & Chemical to be built in 2009, a 650,000 tons / year ethylene glycol unit, Tianjin ethylene intends to construct a 420 000 2009 tons / year ethylene glycol unit, Changchun Tian Yu biotechnology company proposed a 100,000 tons / year ethylene glycol plant, Suzhou Anhui BBCA Biochemical Company intends to maize, cassava starch as raw materials such as construction of a 180,000 t / year ethylene glycol plant. Recent years, with the rapid growth in polyester consumption, the world's ethylene production developed rapidly. In 2008, the world's ethylene production capacity has reached 22.651 million tons / year. Dow Chemical Company is now the world's largest manufacturers of ethylene glycol, respectively, in the United Kingdom and the United States built a production plant. By 2010, Saudi Petrochemical Company's ethylene production capacity of the east will be more than 3.3 million tons / year to replace the Dow to become the world's largest ethylene producer. Global ethylene capacity is concentrated in Asia, the global ethylene market is a strong expansion climax. 2006 to 2010, new capacity in the world more than 8 million tons ethylene glycol / year, of which more than 5 million tons / year capacity concentrated in Saudi Arabia, Iran, Kuwait and other Middle East countries. Middle East over North America to become the world's largest exporter of ethylene glycol. By then, the United States, Europe and Japan and other countries and regions, some of which will be weak because of competition was forced to close. Glycol is expected to total consumption in 2010 will reach 21.88 million tons / year, while total production capacity will reach 27.093 million tons / year in the future overcapacity is a foregone conclusion. Glycol Demand Asia-Pacific region accounted for 60% of the world's total demand over the Middle East will become the world's largest ethylene production and export base. By then, China's ethylene glycol consumption will account for 26% of the world, accounting for 46% in Asia. The future of the Middle East-based production to new places and Asia, mainly China, the rise of consumption, will greatly impact on the world market pattern of ethylene glycol to make major changes in supply and marketing structure. While global ethylene production capacity has been a surplus situation, but yields in Asia can not meet actual needs, had to import large quantities of each of the next few years China will face serious challenges, will be ethylene Alcohol vendors jostling for market. The impact of imports by volume in China is difficult to get rid of some small glycol unit was eliminated fate. Present less of ethylene glycol production, backward technology. To meet the challenge, which takes into account relevant domestic enterprises to adopt advanced technology of the existing ethylene glycol unit to Revamp to increase production, the proposed re-introduction of foreign advanced technology, production scale of new sets of 30 ton / year ethylene glycol over a large plant to expand production scale, and fundamentally ease the contradiction between supply and demand of ethylene glycol, ethylene glycol in the foreign markets to enhance China's competitiveness. At the same time increase the ethylene glycol polyester in the field of non-application development efforts, and gradually change the situation of China's ethylene glycol product uses a single order to resolve the future of the market risk, and promote healthy and orderly and steady development of industry.
