2-imidazolidinone

الوصف

*-Imidazolidinone is mainly used in fabric anti-crease finishing agent and deacetalizing agent, rubber, resin, PA6, etc. as cross-linking agent; poly-EVA, various water-based paints, adhesives, pigments, paints, etc. The agent is separately added into the coating to make the coating have the function of absorbing and decomposing formaldehyde; the inkjet printing ink is used for wetting, anti-blocking and dispersing; the chelating agent and the formaldehyde absorbent in the photosensitive material; and the formaldehyde removing agent in the papermaking industry. It is also an important intermediate for the synthesis of penicillin, a main component of various air fresheners and aldehyde removal agents.
1 Textile industry
Cotton products are composed of long-chain cellulose in which a large number of hydroxyl groups form spatial hydrogen bonds, which are destroyed by heat or external force and then re-randomly combined, which forms fabric wrinkles. When ethylene urea reacts with formaldehyde, it can react with bare hydroxyl groups to form a stable structure and play an anti-wrinkle effect. This method can control the pungent odor caused by the anti-wrinkle treatment of formaldehyde alone, and effectively inhibit the release of formaldehyde.
 
In addition, urea-formaldehyde resin is a commonly used fabric finishing agent, in which the urea-formaldehyde resin remaining on the fabric slowly releases formaldehyde, and the ethylene urea treatment can effectively suppress the release of formaldehyde. Studies have shown that the anti-wrinkle treatment of ethylene urea, such as linen, silk and rayon, has also achieved good results.
 
2 inkjet printing ink
 
Ethylene urea is an important additive in inkjet printing inks and serves a variety of purposes. It includes dispersing pigments, lubricating pipes, preventing the inkjet head from drying in the air, preventing nozzle clogging, and improving ink storage stability. It also improves color contrast and produces high quality prints.
 
3 Adhesive
All kinds of wood-based panels such as plywood, particleboard, fiberboard and composite wood-based panels generally use urea-formaldehyde resin, phenolic resin or melamine resin as adhesive. The annual output of China alone is *0 million cubic meters. These adhesives are formed by the condensation of urea, phenol and melamine with formaldehyde, all of which have the problem of slowly releasing gaseous formaldehyde into the environment. Ethylene urea can be added to these adhesives to effectively reduce formaldehyde release without affecting the bonding effect.
 
4 daily chemicals
 
It is the main component of household formaldehyde scavenger, and can be used as high-performance formaldehyde scavenger, home air formaldehyde strong activity enzyme, formaldehyde long-acting melting medium, glue deodorizer, photocatalyst, floor deodorant care wax, furniture deodorant, Deodorant for vehicles and so on.
 
5 organic synthesis
 
It can be used as a variety of new antibiotic intermediates, such as mezlocillin, azlocillin, as an intermediate for anti-schistosomiasis, and as a basic raw material for the third generation of penicillin; in the biological field, it can produce plant growth. Regulators, bactericides, inhibitors, herbicides, etc., such as: N-chloroformyl**-imidazolidinone, *-chloroformyl**-acetyl**-imidazolidinone, *-chloroformyl **-Methanesulfonyl**-imidazolidinone, N-hydroxyethyl**-imidazolidinone, *-methanesulfonyl**-imidazolidinone, 1,*-dimethyl**-imidazolidinone , *-acetyl**-imidazolidinone, and the like.
