The development of the methyl ethyl ketone industry is restricted, resulting in domestic demand for sec-butanol declining year by year.

Sec-butanol, also known as 2-butanol, methylethylmethanol, chemical formula C4H10O, molecular weight 74.12, is a colorless liquid with a wine smell, flammable, volatile, optically active, and has a chirality in the molecule Carbon atoms can exist in three forms: right-handed, left-handed and racemic. Methyl ethyl ketone and acetic acid are generated when sec-butyl alcohol is oxidized, which are slightly soluble in water and can form an azeotropic mixture with water. They are also soluble in acetone and benzene and are miscible with ethanol and ether.

Sec-butanol is an important chemical intermediate that can be widely used in the synthesis of a variety of chemicals, such as spices, colorants, wetting agents, dyes and lubricants, etc. It can also be used in the production of plasticizers, mineral processing agents, Herbicides, paint cleaners, natural resins, linseed oil solvents, etc. are also the main raw materials for the production of methyl ethyl ketone and sec-butyl acetate. Among them, methyl ethyl ketone is the most important application field. About 90% of the sec-butanol industry is used in the field of methyl ethyl ketone. In addition, sec-butanol also has high energy and high octane number. Without the use of additives and the need to modify the vehicle, it can be used as a substitute for ethanol and MTBE, mixed with gasoline in a certain proportion, and used as a substitute for automobile fuel. gasoline.

According to the “In-depth Market Research and Development Prospects Forecast Report of China’s Sec-Butyl Alcohol Industry from 2023 to 2028” released by the Industrial Research Center, Sec-butanol Industry Since butanol was synthesized in the 1930s, various production processes have been developed, such as the n-butene method, the butanone method, and the sec-butyl acetate method, and the production technology has become relatively mature. At present, the demand for sec-butanol is mainly concentrated in the field of methyl ethyl ketone. However, due to increasingly strict environmental protection regulations, the operating rates of coatings, adhesives, inks and other industries have declined. The methyl ethyl ketone market has relatively shrunk, and industry production conditions have been sluggish, resulting in domestic demand for sec-butanol. Declining trend year by year.

From the perspective of market concentration, in recent years, affected by stricter environmental protection policies and small and sluggish downstream demand, some companies in the domestic sec-butanol industry have withdrawn from the market, which has increased industry concentration to a certain extent. At this stage, there are not many companies in the sec-butanol industry in my country. Key companies include Zibo Haizheng Chemical Co., Ltd., Zibo Qixiang Tengda Chemical Co., Ltd., Lanzhou Petrochemical Co., Ltd., Hunan Zhongchuang Chemical Co., Ltd., etc., and the industry concentration is relatively high. high.

Industrial analysts said that sec-butanol is an important chemical intermediate and is widely used in the synthesis of a variety of chemicals. Such as spices, dyes and lubricants, etc., which are mainly used for dehydrogenation to produce methyl ethyl ketone, an important chemical product. However, affected by factors such as environmental protection policies and the development of the substitute industry, it is difficult for the domestic sec-butanol industry to reverse the industry development trend, and market demand continues to decline. In the future, as the demand for methyl ethyl ketone in automotive coatings, synthetic leather and other fields rebounds, the demand for sec-butanol may rebound, but the scale of demand will still be small.
