Welcome to inquire! Contact: Feng Zhongying. The past 10 years, due to strong demand for ethylene glycol polyester industry, the domestic market demand for ethylene glycol to maintain momentum of rapid growth. Apparent consumption in 1995 was only 656,900 tons of ethylene glycol, 2000 reached 1,957,100 tons, an average annual growth rate of 24.40%. In the 21st century glycol solvent, ethylene glycol apparent consumption continued to grow, in 2002 exceeded 300 million tons mark, reaching 3.0199 million tons, more than the United States to become the world's largest consumer of ethylene glycol, due to Rapid growth in demand, and promote the increase of ethylene glycol polyester resin, the past two years, several sets of large-scale production capacity of ethylene glycol plant put into operation. With the increase of China's ethylene production capacity, production is also increasing. Glycol: the number of hydroxyl groups in the molecule according to the alcohol can be divided into monohydric alcohols, diols and polyols. In diols, two hydroxyl groups attached to adjacent carbon atoms, called a vicinal diol, even called two hydroxyl groups on the same cell-diol carbon atoms. Quasi-diol is a general term referring to ethylene glycol, propylene glycol and other glycols.
