Ethanolamine coatings modified crosslinking agent

Ethanolamine coatings modified crosslinking agent,Phenyl glycidyl ether and hexyl, octyl glycidyl ether and ethanolamine, diethanolamine reaction crosslinking can be obtained from excellent performance and good toughness modification ethanolamine crosslinking agent.

By cresol glycidyl ether and lower aliphatic amine such as divinyl three amine and triethylene tetramine reaction to produce low cost, good performance, can be widely used in general adhesive, anticorrosion, glass fiber reinforced plastic production, etc.
Ethanolamine and traits of the appearance is colorless liquid, colorless transparent viscous liquid at room temperature, has the water absorbability and ammonia smell.

Alkaline aqueous ethanol amine, strong moisture absorption, can absorb acidic gas, heating, and can be absorbed gas release. Emulsification and bubbles. Can and inorganic acids and organic acid salts, generate ester and acid anhydride. Of the amine hydrogen atoms can be acyl halide, halon substitution. Combustible, encounter flame and high temperature are in danger of burning, steam are poisonous.

The dilute solution of ethanol amine has very weak alkaline and irritating, with the increase of the concentration, the eyes, skin and mucosa stimulating. In mice by oral LD50 to 700 mg/kg, rat oral LD50 to 2100 mg/kg. Operation field maximum allowable concentration of 6 mg/m3. Should wear protective equipment when operating.

Colorless transparent sticky liquid at room temperature, has the water absorbability and ammonia smell. With the mixed solvent such as water, ethanol and acetone, slightly soluble in ether and carbon tetrachloride.

Ethanolamine mainly used as synthetic resin and rubber plasticizer, curing agent, promoter and foaming agent, as well as pesticide, medicine and dye intermediates. Is raw material of the synthetic detergent, cosmetics emulsifier, etc. Textile industry as a printing and dyeing brightening agent, antistatic agent, mothproofing agent, cleaning agent. Also can be used as carbon dioxide absorption agent, printing ink additives, oil additives.

A ethanolamine is widely used as acid extracted from various gases such as natural gas purification of liquid components. By ethanol amine hydrochloride cyclization, and six piperazine hydrate can be obtained. A ethanol amine hydrochloride by chlorination sulfoxide chloride generation, to be replaced by sodium thiosulfate, beta can be obtained from amino ethyl thiosulfate. This is a kind of dye intermediates, used in the production of polycondensation turquoise blue 13 g. A ethanol amine react with carbon disulfide in the rubber and the pharmaceutical industry can be obtained from application of intermediates of s-based thiazole phosphorus.




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).


Ethanol amine is the preparation of double oxygen of carbamate pesticide intermediates, are widely used as acid extracted from various gases such as natural gas purification of liquid components. Generated by ethanolamine and fatty acid alkyl alcohol amine is effective foam synergistic agent. Ethanol amine intermediates or emulsifying agent, used in the textile industry as antistatic agent, mothproofing agent, cleaner. By ethanol amine hydrochloride cyclization, and can be obtained hexahydrate piperazine, piperazine in the form of the phosphate or citrate can be used as drive intestinal worms.

Ethanol amine can be used for heavy crystallization of dehydroabietic acid from disproportionated rosin purified.

Ethanolamine by ammonia reaction with ethylene oxide was prepared.

Epoxy ethane, ammonia water solution and circulating ammonia into the stainless steel reactor, together with cooling device, the reaction temperature 30 ~ 40 ℃, the reaction pressure 0.7 ~ 3 mpa. Reaction product into the deamination tower, the removal of ammonia return preparation ammonia solution, ammonia absorber evaporation concentration and drying dehydration the bottom product for a quick crude ethanol amine. Using a vacuum distillation to ethanolamine, diethanolamine, triethanolamine steamed out respectively, purity can reach 98% ~ 99%, epoxy ethane conversion rate of close to 100%, the yield was about 95% ethanol amine. In addition, there are a few by-products polyether generated, in the raw material with a small amount of carbon dioxide can reduce the by-products generated.

Ethanolamine often exist in phospholipid, and often coexist with choline, so also known as ethanolamine. Were also found in the serum protein decay fermented with ethanolamine.

Industrial ethanol amine can be made by ammonia and ethylene oxide reaction. Epoxy ethane, ammonia water into the reactor, the reaction temperature 30 to 40 ℃, 70.9 304 kpa pressure, carries on the condensation reaction to generate one, two, triethanolamine mixture, under the 90-120 ℃ after dehydration concentrate into three decompression distillation to vacuum distillation, according to different boiling point capture fractions, was a purity of 99%, however, ethanolamine, diethanolamine and triethanolamine finished products. In the process of reaction, such as increasing proportion of epoxy ethane, the second, triethanolamine ratio increases, can raise the yield of 2, triethanolamine.
