1. for the synthesis of polyamide resins, surfactants, lubricants, curing agents for epoxy resins, etc.
2. mainly used as solvent and organic synthesis intermediates for the preparation of gas purifier (CO2), lubricating oil additive, emulsifier, photographic chemicals, surfactant, fabric finishing agent, paper reinforcing agent, ammonia carboxyl complexing agent, ash free additive, metal chelating agent, heavy metal hydrometallurgy and cyanide free plating diffusion. Agents, brighteners, ion exchange resins and polyamide resins. The reaction of two B three amine and dicyandiamide can be produced by the preparation of the fixing agent, DFC (Suprafix DFC): 30.9 two B three amines are added to the gear stirred reactor, and 24.8 dicyandiamide is added in the stirring. When the temperature rises to 100, ammonia is released, and then the temperature rises slowly to 145-160 degrees Celsius. The material gradually becomes viscous from liquid. After 5-8 hours of reaction, the reactants were released, then cooled and crushed. Similar fixatives can be obtained by the reaction of ethylenediamine, triethylenetetramine, tetraethylpentamine with dicyandiamide or diethylenetriamine with guanidine carbonate. In addition, the ester ratios of two three amine and dicyandiamide are different, and the viscosity of the products is different. These fixative agents are used for direct dyestuff post treatment to improve fastness, especially washing fastness. With 0.3% fixing agents, cotton washing fastness can be increased from 1 to 4-5. Two B three amine is a high active epoxy resin curing agent, which is mainly used in laminating products, casting products, adhesives and coatings and so on. The general dosage is 5-10, but the aliphatic polyamines have water solubility, high vapor pressure and irritation to the operators' skin, so various kinds of modified varieties have been developed.
3. used as the preparation of ammonia carboxyl complexing reagent, gas purifying agent and resin curing agent.
4. Ammoniacarboxylic complexing agent, solvent of sulfur, acid gas, dye and various resins, saponifier of acidic substance, gas purifying agent. Resin curing agent.
