Applications of 2-Imidazolidinone

2-Imidazolidinone is an organic compound mainly used in various fields for formaldehyde removal; additionally, 2-Imidazolidinone has applications in the textile industry, printing inks, and as a pharmaceutical intermediate.

1. Resin Industry

Adding 2-Imidazolidinone during the production of urea-formaldehyde, phenol-formaldehyde, and furfural resins can remove free formaldehyde.

2. Textile Industry

Cotton products consist of long-chain cellulose, where numerous hydroxyl groups form spatial hydrogen bonds. These bonds can be broken under heat or external force and then randomly recombined, causing fabric wrinkles. Treating fabrics with 2-Imidazolidinone and formaldehyde can react with exposed hydroxyl groups to form a stable structure, providing a wrinkle-resistant effect. Moreover, 2-Imidazolidinone can control the pungent odor of formaldehyde and effectively inhibit its release.

3. Inkjet Printing Inks

2-Imidazolidinone is an important additive in inkjet printing inks, serving multiple functions. It disperses pigments, lubricates the ink path, prevents the inkjet nozzle from drying out in the air, prevents nozzle clogging, and improves ink storage stability. 2-Imidazolidinone can also enhance color contrast and improve the quality of printing.

4. Adhesives

Various types of engineered wood panels typically use urea-formaldehyde, phenol-formaldehyde, or melamine resins as adhesives. These adhesives are formed by the polycondensation of urea, phenol, and melamine with formaldehyde, all of which have issues with formaldehyde release. 2-Imidazolidinone can be added to these adhesives to effectively reduce formaldehyde emissions without affecting the bonding effect.

5. Organic Synthesis

2-Imidazolidinone can serve as an intermediate for various new antibiotics and antischistosomal drugs, and it can also be used as a base material for the production of third-generation penicillins. In the biological field, 2-Imidazolidinone can be used to produce plant growth regulators, fungicides, inhibitors, herbicides, etc.
