Appalication:

Diethylenetriamine is mainly used as a solvent and intermediate in organic synthesis. It is used to produce gas purifier (for CO2 removal), lubricating oil additives, emulsifiers, photographic chemicals, surfactants, fabric finishing agent, paper strengthening agent, ammoniacyl complexing agent, ash free additive, metal chelating agent, heavy metal hydrometallurgy and cyanide-free electroplating diffusion agent, brightener, ion exchange resin and polyamide resin. The color fixing agent SuprafixDFC can be prepared by the reaction of diethylenetriamine and dicyandiamide: 30.9 parts of diethylenetriamine are added to the reactor with gear stirring, and 24.8 parts of dicyandiamide are added under stirring. When the temperature rises to 100 ° C, ammonia begins to be released, and then the temperature slowly rises to 145-160 ° C, and the material gradually becomes viscous from liquid. After the reaction of 5Chemicalbook-8 hours, the reactants are released, cooled and crushed. Similar fixing agents can be obtained by the reaction of ethylenediamine, triethyltetramine, tetraethylpentamine with dicyandiamide, or by the reaction of diethyltriamine with guanidine carbonate. In addition, the ester ratio of diethylenetriamine and dicyandiamide is different, and the viscosity of the product is also different. This type of fixing agent is used for post-dyeing of direct dyes to improve fastness properties, especially for washing. When treated with 0.3% fixing agent, the washing fastness of cotton cloth can be increased from 1 level to 4-5 level. Diethylenetriamine is a highly active epoxy resin curing agent, mainly used in laminate products, casting products, adhesives and coatings, etc., the general dosage is 5-10, but this kind of aliphatic polyamine is water-soluble, high vapor pressure, and has a stimulating effect on the skin of the operator, so various modified varieties have been developed.
