Ethylene diglycol monoethyl ether CAS 111-90-0

What is Ethylene diglycol monoethyl ether CAS 111-90-0?

Ethylene diglycol monoethyl ether is a colorless, transparent liquid at room temperature and pressure. It is a colorless, water-absorbing and stable liquid. It has a moderately pleasant odor. It is miscible with water, acetone, benzene, chloroform, ethanol, ether, pyridine, etc. It has a moderately pleasant odor. Diethylene glycol ethyl ether is often used as a solvent for nitrocellulose, resins, spray paints, dyes, etc. Ethylene diglycol monoethyl ether is a high-boiling point solvent and is also used as a diluent and some chemical intermediates. In the field of fine chemicals, this compound can be used as one of the ingredients in the formula of automobile engine cleaning agents; in organic synthesis, this compound can be introduced into the molecular structure of functional materials through esterification reactions of hydroxyl groups and nucleophilic substitution reactions.

Specifica

Applicazione

1. Coatings and paints

Ethylene diglycol monoethyl ether can be used as a solvent. In coating formulations, it can effectively dissolve resins, pigments and other ingredients. For example, in some water-based coatings, it helps the resin to be evenly dispersed, so that the coating has good fluidity and coating performance, thereby ensuring that the coating can form a uniform and smooth paint film on the coated surface.

Diethylene glycol ethyl ether helps to improve the drying speed of the coating. It can adjust the evaporation rate of the solvent in the coating to avoid defects in the paint film caused by too fast or too slow solvent evaporation, such as orange peel phenomenon (the solvent evaporates too quickly, the paint film surface is uneven) or too long drying time.

2. Ink industry

As an ink solvent, Ethylene diglycol monoethyl ether is used to dissolve resins, dyes and other ingredients in the ink to give the ink a suitable viscosity and fluidity. This is crucial for the transfer performance of the ink during the printing process, and can ensure that the ink is accurately transferred from the printing plate to the printing material (such as paper, plastic film, etc.), forming clear and bright patterns and text.

It can also improve the stability of ink, prevent the ink from precipitation and stratification during storage, and extend the shelf life of ink.

3. Cleaning and degreasing uses

Diethylene glycol monoethyl ether is an excellent cleaning agent component. Since Ethylene diglycol monoethyl ether has good solubility in grease, oil stains, etc., it can be used to clean oil stains on metal surfaces. In industrial production, such as mechanical processing, automobile manufacturing and other industries, it is used to clean processing oil, anti-rust oil, etc. on the surface of parts to ensure that the surface of parts is clean and tidy during subsequent processing or assembly.

It can also be used to clean electronic components. Its ability to dissolve oil stains can effectively remove grease and impurities on the surface of electronic components. Moreover, it has a certain volatility and can dry quickly after cleaning. It will not leave too many impurities on the surface of the components, thereby ensuring the performance of electronic components.

4. Textile printing and dyeing industry

As a textile auxiliary, diethylene glycol monoethyl ether can be used to improve the dyeing properties of fabrics. It can help dyes better penetrate into the fabric fibers and make dyeing more uniform. For example, in the dyeing process of cotton fabrics, polyester fabrics, etc., it is used as a dye cosolvent to improve the dyeing depth and uniformity.

It can also be used in the textile finishing process to adjust the performance of the finishing agent, such as as a solvent component in some softening finishing agents, so that the finishing agent can better adhere to the fabric surface, giving the fabric a soft and smooth feel.
