Hydroxyethylene diphosphonic acid (HEDP) is mainly used in the field of water treatment, and the market share of high-performance products in mainland China is expected to increase
Hydroxyethylene diphosphonic acid (HEDP), also known as hydroxyethyldiphosphonic acid, with the chemical name of 1-hydroxyethyl-1,1-diphosphonic acid and the molecular formula of C2H8O7P2, is an organic compound. HEDP has the advantages of good high temperature resistance, good corrosion inhibition, good synergistic effect and good scale inhibition, and is widely used in the field of water treatment as an organophosphonic acid scale and corrosion inhibitor.
HEDP is usually made from glacial acetic acid and phosphorus trichloride. Phosphorus trichloride is an inorganic compound, which is widely used in the preparation of organophosphorus compounds, and phosphate rock smelting method and chlorine gas penetration method are its main preparation methods. At present, the continental phosphorus trichloride technology has been developed and matured, and its production capacity continues to expand and the output continues to grow. In 2023, the mainland's phosphorus trichloride production will reach nearly 1.85 million tons. The advantages of raw materials will lay a good foundation for the development of the HEDP industry in mainland China.
According to the "2024-2028 Hydroxyethylene Diphosphonic Acid (HEDP) Industry In-depth Market Research and Investment Strategy Suggestion Report" released by the New Thinking Industry Research Center, attracted by the market prospects, the number of enterprises and scientific research institutions in the mainland that have laid out the R&D track of the HEDP industry has been growing, driving the number of patent applications to continue to increase. In 2023, the total number of HEDP-related patent applications in mainland China will reach nearly 200. In the future, with in-depth research and technological progress, the market share of high-performance HEDP in mainland China will be further increased.
HEDP is an organophosphonic acid scale and corrosion inhibitor, which has the advantages of not being easy to hydrolyze, high temperature resistance, corrosion resistance, etc., and can effectively prevent the formation of scale, and is widely used in the field of water treatment. In recent years, benefiting from national policy support and technological progress, the development speed of the mainland water treatment industry has accelerated. In 2023, the scale of the mainland water treatment market will reach nearly 75 billion yuan, creating a record high. HEDP can be used in wastewater treatment, reverse osmosis pretreatment and other scenarios, and its industry prosperity is expected to increase with the growth of application demand in the future.
In addition to the field of water treatment, HEDP is also used in the fields of medical and health care, light textile industry, material protection, electronic and electrical, agriculture and other fields. In the field of medical and health care, HEDP, as a carrier of radioactive elements, is widely used in the diagnosis and treatment of thyroid diseases and renal diseases. In the field of electrical and electronics, it can be used as a cleaning agent for electronic devices.
There are many participants in the HEDP market in mainland China, mainly including Taihe Technology, Jiangshan Co., Ltd., Guohua Chemical, Xintai Water Treatment, etc. Taihe Technology focuses on the R&D and production of organophosphoric acid and organophosphate series products, with an annual HEDP production capacity of 80,000 tons.
Industry analysts said that with the gradual implementation of national environmental protection policies, the mainland water treatment market space continues to expand, which will provide favorable conditions for the development of the HEDP industry. Benefiting from the abundant supply of raw materials and technological progress, the output and quality of HEDP in mainland China have been continuously improved. In the future, with the continuous efforts of local enterprises and related scientific research institutions, the development trend of the HEDP industry in mainland China will continue to improve.
