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 solvents can be divided into two categories: E series and P series based on starting materials and production processes.
The E series is prepared through a 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 Ethylene glycol ether;
Prop series: B Glycolpropyl ether;
Butyl ether series: B Butyl glycol ether, diethylene glycol butyl ether, triethylene glycol butyl ether;
Hexyl ether series: ethylene glycol hexyl ether, diethylene glycol hexyl ether;
Phenyl 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. One end of its molecular structure is a lipophilic group, which can dissolve hydrophobic compounds. It is a hydrophilic group that can dissolve water-soluble compounds. It has a similar structure to surfactant and is known as a "universal" solvent.
Properties of alcohol ether solvents
The physical and chemical properties of alcohol ether solvents change regularly with the change of structure. As the chain length of the alkyl group increases (methyl ether-diethyl ether-propyl ether-butyl ether), its boiling point increases, volatilization slows down, 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 also have the same trend.
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.
