Dimethylacetone (3-pentanone) is an environmentally friendly chemical product, and the acid-acid synthesis method is its mainstream preparation method.

Dimethylacetone, also known as 3-pentanone and diethyl ketone, has a molecular formula of C5H10O and is an organic compound. Dimethylacetone appears as a colorless liquid with an odor of acetone and is soluble in ether and ethanol. Dimethylacetone is flammable and has low toxicity, and is widely used in pharmaceutical manufacturing, pesticide manufacturing, chemical synthesis and other fields.

The preparation methods of dimethyl acetone include acid-aldehyde method, isoprene method, methyl ethyl ketone methanol method, acid-acid synthesis method, etc. The acid-acid synthesis method refers to using two different acids as raw materials, adding a catalyst under heating and pressurizing conditions, and fully reacting to obtain the finished product. This method is green and environmentally friendly, has high technological maturity, high conversion efficiency, and can be continuous Reaction and other advantages, it is suitable for large-scale production and is the mainstream preparation method of dimethyl acetone. In the future, with technological advancement, my country’s dimethyl acetone production capacity and output will increase.

According to the “2023-2028 China dimethylacetone (3-pentanone) industry market in-depth research and development prospect forecast report released by the Industrial Research Center ” shows that dimethyl acetone is widely used in many fields, including pharmaceutical manufacturing, pesticide manufacturing, and chemical synthesis. In the field of pharmaceutical manufacturing, dimethyl acetone can be used as the raw material for anti-influenza drugs; in the field of pesticide manufacturing, dimethyl acetone can be used to make the herbicide pendimethalin; in the field of chemical synthesis, dimethyl acetone can be used as an organic solvent , participate in the synthesis reaction. Benefiting from the accelerated development of downstream industries, my country’s dimethyl acetone market space will further expand.

Dimethylacetone is an environmentally friendly chemical product with good industry development prospects. In April 2022, six departments including the Ministry of Industry and Information Technology and the National Development and Reform Commission jointly issued the “Guiding Opinions on Promoting the High-Quality Development of the Petrochemical and Chemical Industry during the 14th Five-Year Plan”. The document clearly stated that the petrochemical and chemical industry should be promoted to develop in a green and low-carbon direction and strengthen cleanliness. Transform and upgrade production technology and equipment, and vigorously develop green products. With the support of national policies, the prosperity of my country’s dimethyl acetone industry will further improve.

The main players in the global dimethyl acetone market include Italy’s Caffaro Industrie, Germany’s BASF AG (BASF), etc. In the local market, my country’s main manufacturers of dimethyl acetone include Jiangsu Hengxing, Pelco and Besme. At present, Pelko has transferred its dimethyl acetone and other businesses to Besme and is no longer engaged in the production and sales of related products. Besme has many invention patents such as “dimethyl acetone production and refining technology” and has become my country’s leading dimethyl acetone enterprise.

Industry analysts said that dimethyl acetone, as a pentanone series product, has broad application prospects and will take effect in the future as the national environmental protection policy is gradually implemented. , the development speed of the dimethyl acetone industry will further accelerate. Compared with overseas developed countries, my country’s dimethyl acetone industry started late, but its development momentum is rapid, and local companies already have the capability to produce high-performance products.
