Triethylenediamine (TEDA) has a wide range of applications and standardization has become the mainstream trend of industry development.

​​ ​​Triethylenediamine (TEDA), also known as triethylenediamine and triethylenediamine, has a chemical formula of C6H12N2 and is an organic compound. Triethylenediamine appears as white or light yellow crystals, contains an ammonia smell, and is easily soluble in water, ethanol, acetone, benzene and aromatic hydrocarbons. Triethylenediamine has the characteristics of being easily deliquescent, flammable, and easy to sublimate, and is widely used in agriculture, fine chemicals, organic synthesis and other fields.

Aminolysis is the main preparation method of triethylenediamine, ethylene oxide, N-aminoethylpiperazine, diethanolamine, N,N dihydroxyethylpiperazine, N-hydroxyethylpiperazine, piperazine and dichloro Ethane is its main raw material. The piperazine ammonolysis method has the advantages of high process maturity and high yield of finished products, and is suitable for large-scale production. However, currently, due to factors such as international conflicts, energy shortages, and high technical barriers, the output of piperazine and its derivatives in my country is low and cannot meet the production demand for triethylenediamine. The diethanolamine ammonolysis method has the advantages of low production cost and simple operation. It is widely used in our country.

There are many types of triethylene diamine, and industrial triethylene diamine is its representative product, with its market share increasing. In December 2022, the Ministry of Industry and Information Technology released the “Third Batch of Industry Standards Development and Revision and Foreign Language Version Project Plan in 2022”. The document clearly included industrial triethylenediamine in the new materials industry standard project plan. In the future, with the official release and implementation of industry standards, standardization will become the mainstream development trend of my country’s industrial triethylenediamine industry.

According to the “2023-2028 China Triethylene Diamine (TEDA) Industry Market In-depth Research and Development Prospects Forecast Report》shows that triethylenediamine is widely used in agriculture, fine chemicals, organic synthesis and other fields. In the agricultural field, triethylene diamine can be used as an initiator for pesticide production; in the fine chemical industry, triethylene diamine can be used as a catalyst to produce polyurethane coatings, polyurethane rubber, epoxy resin and other products; in the field of organic synthesis, triethylene diamine Diamines can be used as organic synthesis intermediates, and light-stable materials are their end products. Benefiting from the growth in downstream demand, the development space of my country’s triethylenediamine industry continues to expand.

​​​​​Shaoxing Xingxin New Materials Co., Ltd., Hebei Hehui High-tech Materials Co., Ltd., Jiangsu Yake Technology Co., Ltd., and Wuhan Kmic Biomedical Technology Co., Ltd. are the main manufacturers of triethylene diamine in my country. Xingxin New Materials is my country’s leading triethylene diamine enterprise, with an annual production capacity of 1,500 tons, ranking first in the industry.

           Industry analysts said that triethylenediamine, as an important catalyst and organic synthesis intermediate, has broad application prospects in many fields. However, currently, due to factors such as insufficient supply of raw materials, there is a certain gap in the output and quality of triethylene diamine in my country compared with overseas developed countries. In the future, with the improvement of independent research and development capabilities of local enterprises, my country’s triethylenediamine industry will develop in a high-quality direction.
