As the main raw material of acesulfame potassium, the market size of diketene continues to expand

Diketene, also known as diketene, diketene, and acetylketene, has a chemical formula of C4H4O2 and is an organic compound. Diketene appears as a colorless or light yellow liquid with a pungent odor. It is insoluble in water and soluble in most organic solvents. Diketene has the characteristics of active chemical properties and excellent reactivity, and is widely used in food processing, medicine, agriculture, pigments and other fields.
             
The preparation methods of diketene include acetic acid cleavage ketene dimerization method, acetone thermal decomposition method, acetic anhydride pyrolysis method, acetylene oxidation method, monochloroacetyl chloride dehalogenation method, etc. The acetic acid cracking ketene dimerization method refers to the use of an acetic acid cracking furnace to make acetic acid and triethyl phosphate undergo decompression cracking, cooling, separation, distillation, recovery and other processes to obtain finished products. This method has the advantages of good finished product quality, high conversion rate, and green It is the main preparation method of diketene because of its advantages such as environmental protection. The thermal decomposition method of acetone has many by-products, low purity of finished products, and easy to cause environmental pollution, so it is only suitable for small-scale production.

Diketene is the main raw material of acesulfame potassium, accounting for nearly 30% of its production cost. As an artificial sweetener, acesulfame potassium is widely used in beverages and dairy products. my country is one of the main producing countries of Acesulfame K, with production capacity accounting for nearly 70% of the world’s production. In 2022, my country’s acesulfame potassium production will reach 17,000 tons, a year-on-year increase of 13.2%. As the prosperity of the acesulfame potassium industry increases, my country’s market demand for diketene is increasingly strong.

Diketene is widely used in many fields such as food processing, medicine, agriculture, and pigments. In the field of food processing, diketene can be used as a food additive and is widely used in products such as margarine, fermented milk, and lactic acid bacteria beverages; in the field of medicine, diketene can be used as a pharmaceutical intermediate to produce anti-ulcer drugs, vasodilator drugs, and anti-inflammatory drugs. Blood coagulation drugs, etc. Driven by downstream demand, the diketene market continues to expand. According to the “2023-2028 China Diketene Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, in 2022 my country’s diketene market size has reached 2.47 billion yuan.

The main manufacturers of diketene in my country include Shandong Xinhua Pharmaceutical, Suzhou Haobo Technology, Hubei Wuhan Pharmaceutical, Zibo Medical De Chemical, Nantong Acetic Chemical Co., Ltd., Ningbo Wanglong Technology, Anhui Jinhe Industrial, etc. Nantong Acetic Chemical Co., Ltd. and Anhui Jinhe Industrial are the leading diketene companies in my country. According to the annual report of Vinegar Chemical Co., Ltd., the company will achieve revenue of 3.59 billion yuan in 2022, a year-on-year increase of 19.7%.

Industry analysts said that with the accelerated development of the downstream industry, the market demand for diketene is becoming increasingly strong, and the industry development space continues to expand. There are many diketene manufacturers in my country and the market competition is fierce. In the future, as the independent research and development capabilities of local companies continue to improve, my country’s diketene production capacity will be further expanded and output will continue to grow.
