Product Description:
1, 3-dimethyl-2-imidazolinone is a colorless, transparent, low-viscosity liquid with a unique smell of fatty amines. Viscosity (25℃)1.944cps, DMI can be miscible with water, ethanol, ether, acetone, chloroform and other organic solvents, but insoluble in petroleum ether, cyclohexane and so on. Strong polarity, excellent solubility, acid and alkaline resistance. Boiling point: 224-2260C, melting point: 8.200C, flash point: 1200C， refractive index n20/D1.4720, relative density: 1.044.
Usage : 1, 3-dimethyl-2-imidazolinone as an aprotic strong polar solvent, with special physical and chemical properties, widely used in medicine, refining, dyes/pigments, microelectronics, engineering plastics, cleaning and surface treatment and other fields.
1、In the field of medicine as a drug transdermal absorbent application.
2、In the field of polymers, can promote the mixing of raw materials and catalysts, improve polymer chemical properties, thermal properties and mechanical properties.
3、In the field of liquid crystal materials, high-quality porous ultrafiltration membrane can be obtained, which is a liquid crystal positioning agent with stable storage performance.
4、Used as an organic reaction solvent to promote intermolecular and intramolecular condensation reaction to prepare macromolecular heterocyclic compounds.
5、Used as a lithographic process stripping agent. Due to its low viscosity and high dielectric constant, DMI can be used as an electrolyte solvent for high-performance lithium batteries. In addition, its strong permeability, high boiling point and high temperature resistance characteristics, it can also be used as a stripping agent for silicon chip photoresist. Its rapid stripping and non-corrosive metal characteristics can greatly simplify the stripping process and accelerate the chip production rate.
6、Used as detergent. Adding DMI to a mixture of surfactants, bases, alcohols, and polyoxyethylene alkyl ethers gives a powerful detergent. Because DMI dissolves dirt easily, it can also be used to formulate an efficient cleaning solution for cleaning glass and metal.
7、Used as surface treatment agent. DMI can be used as a surface treatment agent to improve the bonding strength between ABS, polyimide, PPS, polytetrafluoroethylene and epoxy resin adhesives.
