Ethylene glycol is the simplest diol compound, which has become an indispensable key material in many fields due to its unique dihydroxyl structure and excellent physical and chemical properties.
* Excellent solubility:
It has good solubility to inorganic salts, dyes and a variety of organic substances, and is an important industrial solvent and reaction medium.
* Suitable thermophysical properties:
It has a high boiling point and moderate viscosity, so that it has excellent comprehensive performance in heat transfer and fluid transportation.
* Excellent frost resistance:
As an ideal antifreeze base fluid, it can significantly reduce the freezing point of the aqueous solution and improve the boiling point, so as to ensure the normal operation of the system under extreme temperature environment.
*Reaction selectivity ：
The two hydroxyl groups can participate in the reaction respectively, providing a flexible molecular design space for fine chemical synthesis.
