Ethylene glycol (EG), also known as ethylene glycol, is the simplest and most important aliphatic diol. It is an important organic chemical raw material, mainly used to produce polyester fiber, antifreeze, unsaturated polyester resin, nonionic surfactant, ethanolamine and explosives.
According to the forecast of China Polyester Association, the output of polyester in China will reach17.3 million tons in 2008, and the demand for EG will reach 6.05 million tons. In 20 10 year, the polyester output will reach about190,000 tons, and the demand for EG will reach about 6.65 million tons. Coupled with the consumption of antifreeze, it is estimated that the total demand for EG in China will reach about 6.36 million tons in 2008 and 765.438+10,000 tons in 2065.438+00. It is predicted that by 20 10, the consumption of EG in China will account for 26% of the world and 46% of that in Asia. It is estimated that the total ethylene glycol production capacity in China will reach about 2.5 million tons in 2008 and 4 million tons in 20 10. However, compared with the demand, even if the factory is producing at full capacity, the output still cannot meet the actual domestic demand and still depends on a large number of imports. Therefore, EG has a good development prospect in China.
