Product name: Ethane-1,2-diol(MEG)
CAS No.:107-21-1
EINECS No.: 203-473-3
Molecular formula: HOCH2CH2OH
Molecular weight: 62.07

Miscible with water, ethanol, acetone, glyceryl pyridine acetate, slightly soluble in ether, insoluble in petroleum hydrocarbons and oils. It has the typical chemical properties of alcohols, and can occur esterification, etherification, oxidation, acetal and other reactions. For example, esterification with carboxylic acids to form ester compounds, and acetal reaction with aldehydes to form acetal.

Usage

Mainly used in the production of polyester polyester, polyester resin, diluent, plasticizer surfactant, synthetic fiber, cosmetics and explosives, and as a solvent for dyes/inks, antifreeze agent for engine formulation, and other dehydrating agents. We mainly produce synthetic resin PET, fiber grade PET (polyester fiber), and bottle grade PET for making mineral water bottles. It can also produce alcohol amine resin, surfactants, formaldehyde and explosives, and is also used as an antifreeze agent.
