2-Imidazolidone (ethylene urea)
Common names: Cycloethyleneurea, Cycloethyleneurea, Ethylene urea, Ethylene urea, 2-Imidazolidone, 2-Imidazolidone
English name: Ethylenurea; 2-Imidazolidinone; 2-Imidazolidone
CAS: 120-93-4
Molecular formula: C3H6N2O
Molecular weight: 86.09
Quality index: ≥ 99.0%
Product Description
EthylenureaCAS: 120-93-4 is a white needle shaped crystal with a melting point of 129-132 ° C and a flash point of 265 ° C. It is soluble in water.
purpose
2-Imidazolidone is mainly used as an anti wrinkle finishing agent and formaldehyde removal agent for fabrics, and as a crosslinking agent in rubber, resin, PA6, etc; Used as a formaldehyde removal agent in EVA, various water-based coatings, adhesives, pigments, paints, etc; Adding it separately to the coating to enable it to absorb and decompose formaldehyde; The ink in inkjet printing has a wetting, anti blocking, and dispersing effect; Chelating agents and formaldehyde absorbers in photosensitive materials; Used as a formaldehyde removal agent in the papermaking industry. It is also a major component of various air fresheners and aldehydes, and an important intermediate in the artificial synthesis of penicillin.
1. Textile industry
Cotton products are composed of long-chain cellulose, in which a large number of hydroxyl groups form spatial hydrogen bonds. These hydrogen bonds are broken and randomly recombined under heat or external forces, forming fabric wrinkles. When ethylene urea and formaldehyde are used together to treat fabrics, they can react with exposed hydroxyl groups to form a stable structure and play an anti wrinkle role. This method can control the pungent odor caused by formaldehyde anti wrinkle treatment alone, while effectively suppressing formaldehyde release.
In addition, urea formaldehyde resin is a commonly used fabric finishing agent, and the residual urea formaldehyde resin on the fabric will slowly release formaldehyde. Ethylene urea treatment can effectively inhibit formaldehyde release. Research has shown that linen, silk, and artificial silk can also achieve good results in anti wrinkle treatment with ethylene urea.
2 inkjet printing ink
Vinylurea is an important additive in inkjet printing ink, playing multiple roles. This includes dispersing pigments, lubricating pipelines, preventing ink nozzles from drying in the air, preventing nozzle blockage, and improving ink storage stability. It can also improve color contrast and achieve high-quality printing effects.
3 adhesives
Various types of artificial boards, such as plywood, particleboard, fiberboard, and composite artificial boards, generally use urea formaldehyde resin, phenolic resin, or melamine resin as adhesives, with an annual production of 80 million cubic meters in China alone. These adhesives are made by 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-day chemicals
It is the main component of household formaldehyde remover and can be used as a high-performance formaldehyde remover, a strong activity enzyme for household air formaldehyde, a long-term formaldehyde melting agent, a glue formaldehyde remover, a photocatalyst, a floor odor removal care wax, a furniture odor removal agent, a car odor removal agent, and so on.
5 Organic synthesis
It can be used as an intermediate for various new antibiotics, such as mezlocillin and aloxicillin, as well as an intermediate for anti schistosomiasis drugs, and as a basic raw material for third-generation penicillin; In the field of biology, it can produce plant growth regulators, fungicides, inhibitors, herbicides, etc., such as N-chloroformyl-2-imidazolidone, 1-chloroformyl-3-acetyl-2-imidazolidone, 1-chloroformyl-3-methylsulfonyl-2-imidazolidone, N-hydroxyethyl-2-imidazolidone, 1-methylsulfonyl-2-imidazolidone, 1,3-dimethyl-2-imidazolidone, 1-acetyl-2-imidazolidone, etc.
