Triethanolamine
chemical properties:
The
triethanolamine alkaline weaker than ammonia (pKa7.82), the nature of the
tertiary amine and alcohol. And low temperature organic acid salt, ester
produced at high temperatures. Generate two to four ligands with a variety of
metal chelates. Hypochlorous acid oxidation to generate the amine oxide.
Periodate oxidation decomposition into ammonia and formaldehyde. Sulfuric acid
generated morpholino ethanol. Triethanolamine at low temperature can absorb
acidic gases, high temperature release.
Triethanolamine is used as
plasticizers, neutralizers, lubricants, additives or corrosion inhibitors, as
well as textiles, cosmetics, humidifying agents and dyes, resins such as
dispersing agent. Curing agent for epoxy resin, with a reference to the amount
of 12-15 parts (by mass), the curing conditions of 80 ℃
/ 4h or 120 ° C / 2h. Can also use synthetic
surfactants, detergents, stabilizers and fabric softener raw materials. Used in
cosmetic formulations and fatty acids into soap and sulfated fatty acid into
the amine salt. The wash liquid used for the removal of acid gases such as
hydrogen sulfide and carbon dioxide in the exhaust gas treatment. Also be used
for the vulcanization activator of natural rubber, synthetic rubber, nitrile
rubber polymerization activators, can also be used as a lubricant and anti-corrosion
additives.
2 triethanolamine
salt of long chain fatty acids is almost neutral and can be used as the
emulsifier of oils and waxes. The oleic acid soap can increase gasoline washing
capacity; stearic acid soap for fragrance cosmetics. Triethanolamine can be
used as casein, shellac, dyes, solvents. Can also be used in industrial gas
purification agents, fiber treatment agents, anti-corrosion additives,
plasticizers, moisturizers, chelating agents, rubber vulcanization accelerator
agents, photographic developer additives, detergents, cement enhancers,
anti-coke additive.
Used as corrosion
inhibitors, triethanolamine is an important inhibitor component of the boiler
water treatment, automotive engine coolant, drilling and cutting oil. Can also
be used for surface active agents, textile specialties, waxes, polishes,
herbicides, petroleum demulsifiers, cosmetics, cement additives, cutting oils.
Used as GC
stationary liquid metal masking agent, with agents, emulsifiers, dry cleaners,
solvents, softeners, and for resin synthesis.Triethanolamine is mainly used
for the preparation of surfactants, detergents, stabilizers, emulsifiers,
fabric softeners. Triethanolamine in the liquid detergent can be improved
removal of oily dirt, especially non-polar sebum, and the same time, by
increasing the alkaline can improve the performance of decontamination. In
addition, liquid detergent, its compatibility is excellent.
Solution of
triethanolamine and its salts as additives of cement grinding process can not
only prevent aggregation and cushion the role of the process of pulverizing
powder to improve the mobility and the packing density of the cement, but also
can reduce the power consumption of the shredder.
In alkaline
zincate galvanized and zinc complex, increase the cathodic polarization of the
bath, the coating crystalline detailed, high levels of lower deposition rate,
the low will cause the coating gray rough, dispersing power poor, the general
content of 20 ~ 30mL / L. However, the viscosity of triethanolamine, the
maximum current density of the bath decreases.
