Diethylenetriamine (DETA) Market Size & Share, by Type (PPO Resin, Modified Polyphenylene Oxide (MPPO)); Application - Global Supply & Demand Analysis, Growth Forecasts, Statistics Report 2025-2037

Growth Drivers

• Growing use as a chelating agent: The metal complexing (chelating) molecule Diethylene Triamine Penta Acetic Acid (DTPA) is a component of the amino carboxylic acid (ethylenediamine-based) group. Ethylene Diamine Tetra Acetic Acid (EDTA) and Hydroxy Ethylene Diamine Tetra Acetic Acid (HEDTA) are further members of this category. There are five acetic acid groups in the diethylenetriamine structure, four in the ethylenediamine structure, and three in the hydroxyethylenediamine structure because one acetic acid group is replaced with a 2-hydroxyethyl group. For many years, these chelating compounds have been employed in various consumer and industrial applications to bind multivalent ions. About 80% of their usage comes from pulp and paper, industrial and domestic cleaning, chemical processing, agriculture, and water treatment. These chelates are also used in the photography, metalworking, and textile industries. In medicine, some of these chelating compounds are approved as carriers for contrast media (like gadolinium or technetium-99), as food additives to improve oral absorption of important metal ions (like iron), or as pharmaceutical ingredients to treat heavy-metal intoxication. 
• Recent advances for efficient CO2 capture: Carbon dioxide (CO2) emissions pose significant threats to the ecological and environmental well-being of human society, serving as a substantial impediment to sustainable development on a global scale. The global CO2 emissions increased from 40.6 billion tons in 2021 to 41.6 billion tons in 2024. According to the Global Carbon Budget, this includes 37.4 billion of fossil CO2 emissions, with the remaining amount coming from land-use change (deforestation). A primary objective for humanity is to mitigate CO2 emissions, and one of the critical challenges of the twenty-first century is the establishment of effective and economical methods for CO2 capture. Carbon capture and storage (CCS) technologies have emerged as one of the most promising solutions for achieving sustainable development, ensuring energy security, and realizing carbon neutrality in the future.
  
  Nevertheless, the advancement of amine absorbents that demonstrate high efficiency and energy-saving capabilities continues to present a major challenge. A research team has developed a novel class of amines by implementing target-specific modifications to the secondary amine group in diethylenetriamine (DETA) with various hydroxyalkyl groups. The resulting amines exhibit enhanced overall efficiency in CO2 capture, particularly regarding absorption and desorption rates as well as recyclability. Notably, the energy consumption required for the regeneration of these innovative amines has been significantly lowered to an impressive 2.78 GJ per ton of CO2. Furthermore, the processes of CO2 absorption and desorption have been meticulously monitored using nuclear magnetic resonance (NMR) techniques. Through the application of density functional theory (DFT) calculations, the mechanism by which the newly developed amines facilitate CO2 capture has been comprehensively elucidated. This targeted modification approach provides a novel pathway for the development of efficient amine absorbents for practical applications in CO2 capture.

Challenges

• Stringent regulations: Strict environmental rules that prohibit the use of hazardous compounds will slow the growth of the diethylenetriamine business. Since diethylenetriamine has certain substantial risks, several regulatory agencies, including the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA), have been enforcing stringent rules regarding its use. In recent years, regulatory bodies worldwide have also been closely examining the storage and transportation of diethylenetriamine. It should be mentioned that diethylenetriamine is harmful because it can corrode both the skin and the eyes. Breathlessness, coughing, and choking are symptoms of severe respiratory tract irritation that can result from inhaling diethylenetriamine spray mist.
• Fluctuating raw material costs: DETA is derived from ethylene dichloride and ammonia, which are petrochemical-based products. Any fluctuations in crude oil prices or supply chain disruptions can impact the growth of the diethylenetriamine market. According to the U.S. Energy Information Administration, in 2024, monthly crude oil prices hovered at USD 70/b to USD 90/b. Despite geopolitical tensions in the Middle East and shipping interruptions in the Red Sea, the trading range for crude oil was very limited due to slow demand and relatively high supply outside of the OPEC+ countries.
