The development trend of 1,4-butynediol (BYD) industry is improving due to the favorable conditions in the upstream and downstream of the industrial chain.

1,4-Butynediol, referred to as BYD, is an organic compound with the chemical formula C4H6O2. It appears as a white to slightly yellow crystalline powder. It is easily soluble in water, methanol, ethanol, acidic solutions, and slightly soluble in chloroform. Insoluble in ether and benzene. 1,4-Butynediol is an important basic chemical raw material, widely used in pesticides, medicines, chemicals, plastics, fibers, leather, electroplating and other fields, and has broad market demand.

1,4-Butynediol is usually prepared by the acetylene-formaldehyde synthesis method and the paraformaldehyde atmospheric pressure solvent method. The acetylene-formaldehyde synthesis method refers to the process of using acetylene and formaldehyde as raw materials and butynyl ketone as the catalyst to generate 1,4-butynediol through a chemical reaction; the paraformaldehyde atmospheric pressure solvent method refers to the process of using paraformaldehyde and cyclic This method uses ethanol as raw material and copper acetylene as catalyst to generate 1,4-butynediol through chemical reaction, filtration, concentration, crystallization and other steps.

Among them, the acetylene-formaldehyde synthesis method is currently the mainstream method for industrial production of 1,4-butynediol. Acetylene and formaldehyde are key raw materials required for the production of 1,4-butynediol. In 2022, domestic acetylene production will be approximately 400,000 tons, and formaldehyde production will be approximately 8.8 million tons. There is sufficient supply of upstream raw materials, providing domestic 1,4-butyne with The development of the glycol industry has created favorable conditions.

1,4-Butynediol has a wide range of applications. In the chemical industry, it is used to prepare a series of organic chemicals such as butanediol, butenediol, γ-butyrolactone, n-butanol, dihydrofuran, tetrahydrofuran, pyrrolidone, etc. An important raw material for products; in the field of electroplating, it is an organic intermediate for preparing primary nickel plating brightener; in the field of plastics and fibers, it is a key solvent required for the production of synthetic plastics and synthetic fibers.

According to the“China 1,4-butynediol (BYD) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that 1,4-butynediol is an important raw material for the preparation of 1,4-butanediol (BDO), and its industry development is greatly affected by the development of the downstream BDO industry. Domestic BDO production in 2022 will be approximately 1.985 million tons, a year-on-year increase of 11.2%. Against this background, the domestic market demand for 1,4-butynediol has exceeded 1.5 million tons in 2022.

At present, domestic 1,4-butynediol manufacturers mainly include Xinjiang Tianzhi Chenye Chemical, Henan Kaixiang Fine Chemical, Sichuan Tianhua Fubang Chemical, Hebei Meiban Engineering Technology, Qujing Longhui Industrial, Dalian Rick Technology, Huai’an Duo Del Chemical, Nanjing Feite Industrial Technology, Shandong Dongafengle Chemical, etc.

Industry analysts said that as a basic chemical raw material, 1,4-butynediol is It has broad application prospects in chemical industry, medicine, pesticides, electroplating and other fields. The development of the 1,4-butynediol industry is greatly affected by the development of downstream industries. Currently, against the background of the continuous increase in domestic 1,4-butanediol (BDO) production, the demand for 1,4-butynediol continues to rise. At the same time, the development of the domestic 1,4-butynediol industry is also benefited by the sufficient supply of upstream raw materials, and the overall development trend is positive.
