Diethylenetriaminepentamethylenephosphonic acid (DTPMP) is a type of scale and corrosion inhibitor with broad market demand.

DTPMP, the full name of diethylenetriaminepentamethylenephosphonic acid, refers to an organic phosphoric acid with the molecular formula C9H28O15N3P5. It appears as a brown-yellow or brown-red viscous liquid, is non-toxic, and is easily soluble in acidic solutions. DTPMP has the characteristics of strong scale and corrosion inhibition, good temperature resistance, good thermal stability, and good chemical stability. It is mainly used as a scale and corrosion inhibitor in water treatment, textile printing and dyeing fields, and can also be used as a metal ion chelating agent, Oxide stabilizers, dispersants, extractants, trace element carriers, concrete additives, etc. are used in papermaking, metal pickling, electroplating, chemical industry and other fields.

Scale and corrosion inhibitors refer to chemical additives that can disperse insoluble inorganic salts in water and prevent them from precipitating and scaling on metal surfaces. They are widely used in oil field water, boiler water, industrial circulating cooling water and other fields. DTPMP is a type of scale and corrosion inhibitor with excellent performance. In addition to its good scale and corrosion inhibition properties, it is also easy to be biodegraded, does not require the addition of dispersants, and has stronger chemical stability in alkaline environments and high temperatures. It is a type of scale and corrosion inhibitor that is currently widely used and has a broad market demand.

DTPMP is a technology-, capital- and scale-intensive industry. At present, the main production method of DTPMP in China is the chemical synthesis method, which refers to using water, formaldehyde, phosphorus trichloride, anhydrous diethylene triamine, etc. as raw materials, through chemical reactions to generate DTPMP liquid, and then precipitating and filtering through absolute ethanol. The method of generating DTPMP solids in multiple steps has the advantages of easy availability of raw materials, low production cost, high output rate, etc., as well as the disadvantages of strict production conditions and long reaction time.

The current domestic DTPMP suppliers mainly include Qingshuiyuan Technology, Taihe Technology, Xianding Biotechnology, Biphosphon Chemical, Dongtao Chemical, Juxinglong Water Treatment, Xintai Water Treatment, etc. Most of them are small and medium-sized enterprises with low output. According to the“China Diethylene Triamine Pentamethylene Phosphonic Acid (DTPMP) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that domestic DTPMP production in 2022 will be approximately 14,000 tons, a year-on-year increase of 13.1%. In the future, with the continuous expansion of DTPMP application fields and the continuous upgrading of local enterprises’ technical processes, my country’s DTPMP output is expected to continue to grow, and the industry is still in a steady development stage.

Industry AnalysisPersonnel said thatDTPMP is a type of chemical additive with excellent comprehensive performance and wide application fields. It has been widely used in chemical industry, papermaking, metallurgy, water treatment, textile printing and dyeing and other fields, and the market demand is broad. At the same time, DTPMP is non-toxic and easily biodegradable. Against the background of continuous strengthening of domestic environmental protection supervision, its market demand continues to grow, and the industry shows a good development trend. However, at present, the scale of domestic DTPMP enterprises is still relatively small and the technical level is still relatively low, resulting in the total output of DTPMP being still relatively low. Therefore, in the future, local enterprises need to accelerate the improvement of their technical level and promote the continuous increase of the total domestic DTPMP production.
