Application field

polymer resin

It can be used as epoxy resin curing agent. The commonly used aliphatic diamine is a general-purpose low-temperature curing agent. In recent years, the most widely used patent reports are ethylenediamine, 2-methylpentanediamine and 1,3-pentanediamine. Diamine. They can significantly improve the performance of coatings as curing agents for epoxy coatings. However, this type of curing agent is generally more toxic, and the epoxy system prepared by it has a large heat release, a short service life, and the cured product is brittle and hard. With epoxy resin as matrix, ethylenediamine as curing agent, acetone as diluent, and quartz as filler, it can be formulated into an ideal universal cementitious material, which has firm bonding, high temperature resistance, oil resistance, water resistance, acid and alkali resistance, low temperature resistance, Aging resistance and high insulating properties. It can be widely used in the repair of motorcycles.

In addition, both ethylenediamine and high-carbon ethyleneamine in the ethyleneamine series products can produce polyamide resins with low molecular weight. Polyamide main resin with low relative molecular weight is made by polycondensation of dimer acid and diamine or ethylene polyamine. It is divided into two categories: reactive type and non-reactive type. , widely used in shipbuilding, automobile, civil construction and other fields; the latter is mainly used as hot melt adhesive and ink, plastic printing, electrical and textile printing and dyeing and other fields.

Printing and dyeing industry

Manufacture of finishing agents, color-fixing agents, and fiber surfactants. For example, treating wool with ethylenediamine can break the disulfide bonds in the wool, making the wool more sparse and soft, making it easier for the dye to diffuse into the fiber; at the same time, the wool can form aminoalanine, which increases the dyeing; In addition, ethylenediamine can also change the surface activity of wool and promote the adsorption of dyes by wool. Some people have studied the process of pretreating wool with ethylenediamine, and researched the performance of wool after pretreatment. It was found that pretreating wool with ethylenediamine reduces the temperature of wool dyeing, shortens the dyeing time, and improves the quality of the product. increase and save energy.

Ethylenediamine or other polyvinylpolyamines and fatty acids can be made into various cationic surfactants, which are used in shampoos, textile softeners and other industrial fields; ethylenediamine hydroxyethyl imidazolines can be converted into amphoteric surfactants It is a high-grade surfactant with minimal irritant toxicity; the surfactant condensed with diethylenetriamine and fatty acid can be used as asphalt emulsifier, oilfield corrosion inhibitor and epoxy resin curing agent; especially The demulsifier used in oil fields produced with polyethylene polyamine as raw material grows faster.

Diethylenetriamine or polyamide and epichlorohydrin as raw materials can produce polyamide-epichlorohydrin resin (PPE), which is an important wet strengthening agent for papermaking. Wet strengtheners are used to help paper increase its strength in contact with water or in a humid environment. Polyamide-epichlorohydrin resin is an excellent wet strengthening agent, mainly used in corrugated cardboard, napkins, toilet paper, baby diapers, various disposable clothing and bedding for hospitals, etc.

Oil additives

The reactant of ethylenediamine and sulfur can improve the thermo-oxidative stability of lubricating oil of zinc diisopropyldithiophosphate, and the fatty acid amine salt or polyurea compound of ethylenediamine can also be used as lubricating oil thickener, lubricating oil Oil extreme pressure agent. Ethylenediamine also has special industrial applications in fuel oil. For example, the reaction products of ethylenediamine and chlorinated polyisobutylene can be used as gasoline detergents. These products can improve the rust resistance of gasoline after neutralization with carboxylic acid. The alkylation and acrylated products of ethylenediamine can be used as diesel detergents, anti-coking additives, and compositions containing ethylenediamine can be used as diesel cetane number improvers.

Electroplating industry

The application of ethylenediamine in the electroplating process mainly includes electroplating copper, electroplating palladium, electroplating nickel and electroless nickel boron, electroless copper, electroless palladium and so on. The addition of ethylenediamine to the electroplating solution promotes fine crystallization of the coating layer, allowing the working current density and the solution leveling ability to be improved accordingly. Because ethylenediamine can have a complex reaction with the metal to be plated, the solubility of the electrode is improved and the buffering effect of the solution is enhanced. Some people have studied the method of reducing divalent nickel ions to elemental nickel with hydrazine hydrate using ethylenediamine as a complexing agent under strong alkaline conditions. The yield of nickel powder is over 90% and its purity is over 99%. By this method, not only nickel is recovered, but also environmental pollution is reduced.

pesticide industry

Ethylenediamine is mainly used in the production of dithiocarbamate fungicides in pesticides, the main varieties are mancozeb, mancozeb, mancozeb and other varieties. This is a preventive broad-spectrum contact fungicide that has been used since 1940 to control mildew, trachoma, scarring, rust and blight in fruits, vegetables, potatoes, and grains. After examining the potential carcinogenic risk of such products, in 1989 the US Environmental Protection Agency recommended restricting their use in most grains, including 45 important grains that require safety supervision. By July 1992, a California federal court had declared a ban on the use of . Due to the wide application and good efficacy of these pesticides, they have become the main varieties of non-systemic protective fungicides, and have been exported to foreign countries in large quantities. Although foreign countries are not interested in the production of such products, they are the leading and still developing products. The production method is to react ethylenediamine and carbon disulfide under the action of NaOH or ammonia water, and then react with zinc salt or manganese salt.

Among other fungicides based on ethylenediamine, the most important are imidazoline compounds, such as 1-heptadecyl-2-imidazoline, due to the reaction between ethylenediamine and stearic acid, its acetate can control apple trachoma, leaf spot of cherry leaves, etc. The 2:1 complex of ethylenediamine and copper sulfate can control hydrophilic fungi.

Pharmaceutical production

Both ethylenediamine and high-carbon ethyleneamine can be used for pharmaceutical production, and about 20 kinds of pharmaceutical varieties can be produced, mainly including aminophylline, metronidazole, keguandiazem, etc., most of which are traditional medicines. For example, theophylline is added to anhydrous alcohol containing equimolar ethylenediamine under vigorous stirring, and after several hours, the precipitate is collected by filtration. Wash with cold ethanol and dry at low temperature to obtain aminophylline.

chelating agent

Both ethylenediamine and polyethylene polyamine can be used as raw materials for the production of chelating agents. (HEDTA) and ethylenediaminetetramethylphosphinic acid and salts (EDTPA), etc., are widely used in the imaging industry, rubber processing industry, food, medicine, hygiene products, water treatment, paper and textile industries, etc.
