Uses of diethylenetriamine
¡¾Purpose 1¡¿
Used for the preparation of ammonia carboxyl complexing reagent, gas purifying agent and resin curing agent
¡¾Purpose 2¡¿
Used in the synthesis of polyamide resins, surfactants, lubricants, epoxy resin curing agents, etc.
¡¾Purpose 3¡¿
It is mainly used as a solvent and organic synthesis intermediate for the preparation of gas purifiers (for CO2 removal), lubricating oil additives, emulsifiers, photographic chemicals, surfactants, fabric finishing agents, paper strengthening agents, and ammonia Mixture, ashless additive, metal chelating agent, heavy metal hydrometallurgy and cyanide-free plating diffusion agent, brightener, ion exchange resin and polyamide resin, etc. The color fixing agent Suprafix DFC (Suprafix DFC) can be prepared by the reaction of diethylenetriamine and dicyandiamide: add 30.9 parts of diethylenetriamine into the reactor with gear stirring, and add 24.8 parts of Dicyandiamide. When the temperature rises to 100¡ãC, ammonia begins to be released, and then the temperature rises slowly to 145-160¡ãC, and the material gradually becomes viscous from liquid. After reacting for 5-8 hours, the reactants were released, cooled and pulverized. A similar fixing agent can be obtained by reacting ethylenediamine, triethylenetetramine, tetraethylenepentamine and dicyandiamide, or reacting diethylenetriamine and guanidine carbonate. In addition, the ester ratios of diethylenetriamine and dicyandiamide are different, and the viscosity of the resulting products is also different. These fixatives are used in post-dyeing treatments with direct dyes to improve fastness properties, especially wash fastness. Treated with 0.3% color fixing agent, the washing fastness of cotton cloth can be improved from grade 1 to grade 4-5. Diethylenetriamine is a highly reactive epoxy resin curing agent, mainly used in laminated products, casting products, adhesives and coatings, etc., the general dosage is 5-10 parts, but this type of aliphatic polyamine is water-soluble The pressure is high, which has a stimulating effect on the skin of the operator, so various modified varieties have been developed.
¡¾Purpose 4¡¿
Ammonia carboxyl complexing agent, solvent for sulfur, acid gas, dyes and various resins, saponification agent for acidic substances, gas purifier. Resin curing agent.
