Domestic hydrocyanic acid production capacity continues to increase, and the industry has good development prospects

Hydrocyanic acid is an extremely weak acid, which refers to an aqueous solution of hydrogen cyanide. Hydrocyanic acid is a Class A inorganic highly toxic substance. Inhaling high concentrations of hydrogen cyanide gas in a short period of time can cause immediate respiratory arrest and death. Hydrocyanic acid has a wide range of uses. The main application areas include nylon, acrylonitrile and acrylic resin, pesticides, electroplating, mining, etc.; the main production methods include formamide dehydration method, methane ammonia oxidation method, methane ammonia dehydrogenation method, acrylamide Chemical oxidation method, light oil cracking method. Among them, the propylene ammonia-oxidation method is the mainstream production method of hydrocyanic acid in my country.

In recent years, against the background of increasing domestic market demand for nylon 66, adiponitrile production technology has continued to make breakthroughs and upgrades. Hydrocyanic acid, as an important raw material for the two-step production of adiponitrile independently developed in my country, has seen increasing market demand. At the same time, hydrocyanic acid is also an important raw material for the preparation of glyphosate, the most widely used and produced herbicide in my country. At present, under the background of continuous development of domestic hydrocyanic acid application field, its domestic production capacity and demand are constantly increasing.

Specifically, the first phase of the 90,000 tons/year hydrocyanic acid plant of China Chemical subsidiary Tianchen Qixiang New Materials will be completed and put into operation in March 2022. The first phase of the 60,000 tons/year hydrocyanic acid plant of Sichuan Jiuyuan High-tech Materials will be put into operation in 2022. It was first announced in March 2020 that Yongli Chemical’s 80,000 tons/year hydrocyanic acid plant will begin bidding and procurement in April 2022. Currently, against the backdrop of increasing domestic hydrocyanic acid production capacity, its output continues to increase. According to the“China Hydrocyanic Acid Industry 2022-2026” released by the Industrial Research Center Market Analysis Research Report shows that domestic hydrocyanic acid production in 2021 will be approximately 531,000 tons.

Because hydrocyanic acid is highly toxic and easy to decompose and volatilize, hydrocyanic acid is generally not sold as a raw material at present. The main products sold are mainly its derivatives, including acetone cyanohydrin, sodium cyanide, potassium cyanide and other cyanide products. From the perspective of the sodium cyanide market, sodium cyanide is an important basic chemical raw material with a wide range of downstream applications. At present, my country has become the largest producer of sodium cyanide in the world. Domestic sodium cyanide companies are mainly distributed in Sichuan, Shandong, Gansu, Shanxi, Henan, Shanghai and other regions. The larger companies mainly include Shuguang Chemical, Ziguang Chemical, Hongsheng Chemical, Chengxin Group, Shanghai Petrochemical, etc.

Industrial analysis personnel said that in recent years, driven by the rapid development of pesticides, nylon and other industries and the increasing demand for hydrocyanic acid derivatives, , the new domestic hydrocyanic acid production capacity continues to increase, which in turn drives its output to continue to increase, and the industry development prospects are good. The derivatives generated by hydrocyanic acid are mostly fine chemical intermediates and have important uses in the fields of pesticides, medicines, dyes, metallurgy, etc. In the future, as domestic research on hydrocyanic acid continues to deepen and technology continues to improve, the categories of its derivative products will continue to increase. , the application fields will continue to expand, and the future industry development potential is huge.
