Diethylenetriamine
Mainly used as solvent and organic synthesis intermediates, used for making gas purifying agent (CO2), lubricating oil additive, emulsifying agent, photographic chemicals, surface active agent, fabric finishing agents, paper strengthening agent, complexone, ash-free additives, metal, hydrometallurgy of heavy metals and chelating agent without cyanide electroplating diffusion agent, brightener, ion exchange resin and polyamide resin, etc.
By diethylenetriamine and dicyandiamide reaction can be prepare in fixing agent Sue Mr Fisker DFC Suprafix (DFC) : to add 30.9 to diethylenetriamine with gear mixing reactor, add 24.8 under stirring dicyandiamide.
When the temperature rises to 100 ℃, the began to release ammonia, and then slowly to a temperature of 145-160 ℃, material by liquid gradually become sticky.
After 5-8 hours, the reactants are released, cooled and crushed.
The reaction of ethylenediamine, triethylamine, tetramine and dicyanamine, or diethylamine and guanidine, can be similar to a colouring agent.
In addition, the ratio of diethylenetriamine and dicyanide is different, and the consistency of the resulting product is different.
This type of colouring agent is used for the treatment of direct dyestuff dyeing to improve fastness, especially washing fastness.
With 0.3 percent colouring agent, cotton wash fastness can be raised from 1 to 4-5.
Diethylenetriamine as highly active epoxy resin curing agent, mainly used for laminated products, casting products, adhesives and coatings, etc., the general dosage for 5-10, but this kind of aliphatic amine with water-soluble, vapour pressure is higher, the operator may stimulate the skin, therefore the development of various modified varieties.
