Glycol ethers are one of the most widely used aqueous solvents, having two functional groups, ether and alcohol, in one molecule. The production of glycol ethers is 2-step. The first step involves the reaction of alcohol and ethylene oxide to produce a mixture of mono, di and heavier glycol ethers. Then, in the second step, the resulting mixture is distilled to separate all its components from each other. This liquid with high boiling point and low volatility and odor is widely used as a solvent in many industries.
General applications
Use as a solvent
Glycol ethers are characterized by high solubility, chemical stability and compatibility with water and a number of organic solvents.
The unique solvent properties of glycol ethers are due to the presence of double functional groups in these materials. Among their other properties, the following can be mentioned:
A mild-smelling solvent for many resins, oils, waxes, fats and dyes
Dissolved in most polar and non-polar organic solvents
Solubility in water in all proportions
Other applications
The extraordinary solubility of these materials has led to the use of certain glycol ethers in various applications:
* Color solvent in textile, pulp and wood industries
* Solvent for grease and soot in industrial cleaners and special formulations
* Halal for agricultural pesticides
* Solvent and co-solvent for common varnishes, glazing, rusting of industrial coating systems
Different grades
Butyl glycol, butyl diglycol
