n-pentanol has high technical barriers and good development prospects

n-pentanol, also known as 1-pentanol, is an organic compound with the chemical formula C5H12O. It is a colorless liquid, slightly soluble in water, soluble in acetone, and miscible in most organic solvents such as ethanol and ether. It is mainly used as an organic compound. Synthesized, it can also be used as coating solvent, flotation agent for non-ferrous metals, and anti-foaming agent for boiler water.

n-Amyl alcohol is a technology-intensive industry. The research and development, optimization, finalization, and operation of the production process all involve specialized knowledge and technology, and the technical threshold is relatively high. At present, only a few companies in the world have large-scale production capabilities of n-pentanol, such as Qilu Petrochemical and Dow Chemical.

The production process of n-pentanol is as follows: raw oil and 30% hydrochloric acid are pumped from the storage tank into the acidification kettle for acidification treatment. The acidified material is distilled in the distillation tower, and the temperature is controlled at 150°C and the pressure is -0.1MP. , the crude n-pentanol product obtained at the top of the tower is condensed by the condenser, and then the material enters the liquid receiving tank. Part of the material in the liquid receiving tank is refluxed, and part of it enters the next-stage distillation tower for further distillation; after being condensed by the condenser, high-purity n-pentanol is obtained Enter the liquid receiving tank and get the finished product.

Affected by factors such as raw material price fluctuations and market supply and demand, the average price of n-amyl alcohol in China has fluctuated in recent years. According to the “2023-2028 n-pentanol industry market in-depth research and investment prospect forecast analysis report released by the Industrial Research Center, The price of n-amyl alcohol in China in 2022 is 25,000 yuan/ton.

n-Pentyl alcohol is an important raw material for the synthesis of n-pentene. n-Pentene is a high value-added fine chemical intermediate and an important raw material for the production of 1,2-pentanediol. It also has good application prospects in the fields of oil additives, plastic modification, organic synthesis and other fields. The n-pentene industry has extremely high technical barriers, and Sasol Group (Sasol) occupies the majority of the global market share. In recent years, with the development of technology, domestic 1-pentene has developed rapidly, and Xinxiang Jujing Chemical Co., Ltd. has achieved large-scale production of 1-pentene.

In recent years, with the continuous development of production technology and the increase in demand, the domestic 1,2-pentanediol industry has become increasingly enthusiastic about investment, forming a strong support for the demand for n-pentene products. For example, in July 2022, Xinxiang Jujing Chemical Co., Ltd.’s 3,000 tons/year 1,2-pentanediol technical transformation project was approved; in January 2023, Anhui Runyan Technology Co., Ltd.’s 5,000 tons/year 1,2 The first public announcement of public participation in the environmental impact assessment of the pentanediol technical transformation project.

Industry analysis stated that in the future, with the continuous advancement of domestic technology and the development of the downstream n-pentene market, there will be more domestic More companies entering the n-pentanol industry will drive the growth of n-pentanol industry production capacity and gradually replace imported products.
