Definition and Usage Areas Mono ethylene glycol
Mono ethylene glycol is colorless transparent sticky liquid with sweet taste and moisture absorbing ability. It is also miscible with water, lower aliphatic alcohols, glycerol, acetic acid, acetone, ketones, aldehydes, pyridine and similar coal tar bases. It is slightly soluble in ether but practically insoluble in benzene and its homologues, chlorinated hydrocarbons, petroleum ether and oils.
- Mono ethylene glycol is mainly used as a raw material for the production of antifreeze agent and polyethylene terephthalate (polyester fiber raw material and plastic material) for the preparation of automobile cooling systems.
- Also, synthetic resins, solvents, lubricants, surfactants, softeners, humectants, explosives, etc. It can also be used in production.
- Glycol can often be used as an alternative to glycerol and is often used as a hydrating agent and solvent in the tanning industry and pharmaceutical industry.
- Glycol has a strong solubility, but can be easily oxidized to toxic metabolic oxalic acid and therefore not widely used as a solvent. Ethylene glycol can be added to the hydraulic fluid and used to prevent the oil-based hydraulic fluid from melting on the rubber of the system.
- Water-based hydraulic fluid with ethylene glycol as the main component is a combustible hydraumatic fluid and can be applied to aircraft, automobiles and high-temperature molding machine.
- As antifreeze in emulsion paints, aqueous systems.
- It is used as a solvent for casein, gelatin, dextrin, some phenol-formaldehyde resins, alkyd resins and dyestuffs.
- It also gives the paint slipperiness and ease of application. Mono ethylene glycol is also used as a heat-transfer agent.
