Neopentyl glycol is widely used in polyester resin and other industries, with great market potential

neopentyl glycol is mainly used to produce saturated polyester resin, and its derivatives are widely used in coatings, automobiles, textiles, pesticides, plastics, petroleum and other fields. The unique neopentyl structure of the saturated polyester resin produced from neopentyl glycol makes the powder coating and high solid component coating prepared from neopentyl glycol have excellent fluidity, flexibility, chemical stability, weather resistance, chlorine resistance, thermal stability and ultraviolet radiation resistance. With the strengthening of people's awareness of environmental protection, the rapid development of environmental protection coatings such as powder coatings and high solid component coatings has led to the increasing application market of neopentyl glycol. In addition, neopentyl glycol is also used in unsaturated polyester resin, medicine, adhesive blending and alloy technology, which refers to mixing two or more polymers in a certain proportion, and has great market potential

at present, western developed countries are committed to the development of new application fields of neopentyl glycol. At present, the world neopentyl glycol market is about US $5.22 billion, with an annual growth rate of 6%. The world's leading producers of neopentyl glycol are BASF, Eastman Chemical, Mitsubishi Gas Chemical and LG Chemical. LG Chemical Company is expanding the capacity of neopentyl glycol. The company invested US $17.4 million to expand the capacity of neopentyl glycol to 50000 tons/year, and increased its efforts to enter the Chinese market. It plans to make its neopentyl glycol account for 15% of the world market and 25% of the Chinese market

there are three neopentyl glycol production plants in China. BASF Jihua neopentyl glycol Co., Ltd. has a current unit capacity of 15000 tons, and plans to expand to 25000 tons in 2005. The production process is advanced. 4. The instruments should be placed in a dry, clean and vibration free environment. The product price is higher than that of the other two manufacturers, and is basically the same as that of imported products; The total capacity of Shandong Linzi Yongliu Chemical Co., Ltd. reaches the maximum stress of 20000 tons of tested materials; Shandong Dongying Dongchen group company has a production capacity of 7000 tons

it is predicted that China's demand for neopentyl glycol will be about 86400 tons by 2008. At that time, although China's domestic capacity can be increased to 52000 tons, even if it is produced at full capacity, it cannot meet the market demand, and there will still be a market gap of 30000 ~ 40000 tons. It is suggested that enterprises planning to build neopentyl glycol projects should focus on the following three aspects. He pointed out that first, the supply of raw material isobutyraldehyde should be guaranteed. Isobutyraldehyde is an intermediate for carbonyl synthesis of butyl octanol. To produce neopentyl glycol, we must first implement the supply of raw materials for isobutyraldehyde. Second, be close to the market. China's neopentyl glycol consumption market is mainly concentrated in the Pearl River Delta and Yangtze River Delta, and new neopentyl glycol projects should be close to the market. Third, pursue technological progressiveness. Advanced process technologies such as condensation hydrogenation of BASF Jihua neopentyl glycol company should be adopted. The sodium formate process is relatively backward, and cannot be compared with the condensation hydrogenation process in terms of product quality, economic indicators and environmental protection requirements
