The production process of tris(2-hydroxyethyl)isocyanurate still has defects and there is still room for improvement in product quality.

Tris(2-hydroxyethyl)isocyanurate (THEIC) is a fine chemical product with relatively active chemical properties and high chemical and thermal stability. It is mainly used in antioxidants, coatings, and plasticizers. The production of agents, stabilizers, flame retardants and other products is widely used in rubber, electronics, textiles, plastics and other fields. The application demand is high and the industry has developed rapidly.

In terms of production, a production process that does not directly use cyanuric acid as raw material has high equipment requirements and harsh operating conditions, so it is currently rarely used. The other is a direct production process using cyanuric acid as raw material. According to different catalysts, it can be divided into four categories, namely the chlorohydrin method, the ethylene carbonate method, the ethylene oxide method and the isocyanate method. , the chlorohydrin method has a more complicated process, a long reaction cycle, and it is difficult to refine the crude product; the ethylene oxide method has higher yield, simple process, and low investment, but has higher requirements for solvents. At present, domestic companies mainly use epoxy Production is carried out by the ethane process; the source of the raw material ethylene carbonate required for the production of the ethylene carbonate process is limited, so the production cost is relatively high; the production of the isocyanate process requires higher equipment and the operation is more demanding.

According to the“Research Report on Application Market Demand and Development Opportunities of China’s Tris(2-Hydroxyethyl) Isocyanurate Industry from 2021 to 2026” released by the Industrial Research Center It shows that tris(2-hydroxyethyl)isocyanurate was first developed in the United States and was subsequently produced and used in Japan, Germany and other countries. The global production capacity of Zhongsan (2-hydroxyethyl) isocyanurate is approximately 30,000 tons/year. Currently, the world’s major tris(2-hydroxyethyl)isocyanurate manufacturers include Japan’s Mitsubishi, BASF, United Chemical Company, and Sankasei Corporation. my country’s current production capacity of tris(2-hydroxyethyl)isocyanurate is about 10,000 tons/year. The main production companies are Changzhou Huafa, Jiangdong Chemical, Wujin Nanyang Fine Chemical, Zhongzheng Chemical, Jianbang Chemical, Weiye Chemical, Wuhu Chemical and other enterprises, but it is difficult to guarantee the quality and output of domestically produced products.

Industrial analysts said that tris(2-hydroxyethyl)isocyanurate, as a fine chemical product, has a wide range of applications. Driven by the development of terminal industries, the market demand for tris(2-hydroxyethyl)isocyanurate is relatively stable. In terms of production, there are four main production processes for tris(2-hydroxyethyl)isocyanurate. Currently, the ethylene oxide method is mainly used for production. However, this process also has the disadvantage of high solvent requirements. In the future, the three ( The production process of 2-hydroxyethyl) isocyanurate needs to be continuously improved and optimized to reduce costs, reduce by-product formation, and reduce toxicity while improving product quality and expanding application scope.
