Diethylene Glycol
Diethylene glycol is an organic compound with the formula (HOCH₂CH₂)₂O. It is a colorless, practically odorless, poisonous, and hygroscopic liquid with a sweetish taste. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. DEG is a widely used solvent.
Applications
1.Unsaturated Polyester Resins
Polyester resins derived from DEG are flexible in nature. They are used as low pressure laminates for glass fibres, asbestos, cloth and paper.
2.Coolants
DEG can be used in cooling systems as it increases the boiling temperature considerably there by enabling the coolant perform more effectively in carrying off the excess heat generated by auto engines.
3.Pesticides
DEG is primarily used to encapsulate granules of phorate pesticide.
4.Rubber Compounding
For coloured rubber products such as hawai chappals, DEG is used as an additive along with silica filler compounds to prevent the absorption of other ingredients such as the accelerator used in the rubber compounds.
5.Plastisizer
Benzoic acid is esterified with Diethylene Glycol DEG to produce DEG Dibenzoate . It finds an application as plasticizer in PVC Compounds , PVA adhesives and moulded urethanes.
6.Polyurethane foams
DEG is condensed with adipic acid or other poly functional acids to give polyurethane intermediate which upon polymerisation with di-iso-cyanate and subsequent reaction with water form polyurethane foams.
7.Polyethylene Glycols
DEG reacts with EO to form higher polyethylene glycols which find application in pharmaceutical, brake fluids, cosmetics.
8.Paints
Diethylene Glycol DEG is used as a modifier in the manufacture of alkyd resins used in formulating paints.
9.Grinding Aid
DEG is Used as a grinding aid in Cement industry, in order to achieve higher fineness and smooth mill operations, increase throughput and also reduces energy consumption.
