Characteristics and applications of alcohol ether solvents

solvagent is a A liquid that can dissolve solid, liquid or gas solutes and then become a solution. The so-called organic solvent is an organic compound containing carbon atoms. Solvents usually have a relatively low boiling point and evaporate easily, or can be removed by distillation, leaving the dissolved material behind. As the largest category of solvents, organic solvents can be divided into three categories according to their chemical structures: hydrocarbon solvents, oxygen-containing solvents and halogenated hydrocarbon solvents. Alcohol ether solvent is a type of oxygen-containing solvent. Due to its own characteristics, it is widely used in coatings, inks, cleaning and electronics industries.

Classification of alcohol ether solvents

Alcohol ether solvent can be selected according to the starting materials and production process Divided into two categories: E series and P series.

E series is prepared through ring-opening reaction with ethylene oxide as the core

Methyl ether series: diethylene glycol methyl ether, triethylene glycol methyl ether;

Ether series: diethylene glycol ether, triethylene glycol ether;

Propyl ether series: ethylene glycol propyl ether;

Butyl ether series: ethylene glycol butyl ether, diethylene glycol butyl ether, triethylene glycol butyl ether;

Hexyl ether series: ethylene glycol hexyl ether, diethylene glycol Ethylene glycol hexyl ether;

phenylene ether series: Ethylene glycol phenyl ether, diethylene glycol phenyl ether;

Acetate series: ethylene glycol, butyl ether acetate, diethylene glycol butyl ether acetate.

P series is prepared through ring-opening reaction with propylene oxide as the core

Methyl ether: propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether;

Take diethylene glycol hexyl ether as an example. Its molecular structure has a lipophilic group at one end, which can dissolve hydrophobic compounds, and a hydrophilic group at one end, which can dissolve water-soluble compounds. It interacts with surfactants. It has a similar structure and is known as a "universal" solvent.

Properties of alcohol ether solvents

The physical and chemical properties of alcohol ether solvents show regular changes with the change of structure. As the chain length of the alkyl group increases (methyl ether-ethyl ether-propyl ether-butyl ether ), its boiling point increases, volatilization slows, water solubility decreases, and viscosity increases; as the number of glycols increases (monopropylene glycol-dipropylene glycol-tripropylene glycol-polypropylene glycol), its boiling point, volatility, water solubility, and viscosity There is also the same trend of change.

Advantages of alcohol ether solvent products

1. Good wetting properties;

2. Low odor;

3. A surface-like structure can be used in cleaning;

4. Coupling effect , improve formula stability;

5. The evaporation speed is controllable.
