Ethylene glycol (glycol; 1,2 dioxyethane; etandiol-1,2), HO — CH2 — CH2 — OH — the simplest representative of polyols (polyatomic alcohol). In the cleared look represents transparent colorless liquid of slightly oily consistence. Has no smell and possesses sweetish taste.
Thanks to the low cost ethylene glycol has found broad application in equipment.
- As component of automobile antifreezes and brake fluids that makes 60% of its consumption. Mix of 60% of ethylene glycol and 40% of water freezes at -45 °C. Korrozionno is active therefore he is applied with corrosion inhibitors;
- As the heat carrier in the form of solution in cars, in systems of liquid cooling of computers;
- In production of cellophane, polyurethane and some other polymers. This second main application;
- As solvent of colorants.
