It is mainly used in making polyester, polyester resin, hygroscopic agent, plasticizer, surfactant, synthetic fiber, cosmetics and explosives, as solvent for dyes/inks, antifreeze for engine, gas dehydrating agent, manufacturing resin, wetting agent for cellophane, fiber, leather and adhesive. It can produce synthetic resin PET, fiber grade PET namely polyester fiber, bottle chip grade PET for making mineral water bottle, etc. Also can produce alkyd resin, glyoxal, etc., also used as antifreeze. In addition to being used as anti-freeze agent for automobile, it is also used for conveying industrial cooling capacity, which is generally called refrigerant carrier.
Solubility: It can be mixed with water and other organic solvents.
Propylene Glycol is a viscous colourless liquid which is nearly odourless but possesses a faintly sweet taste.Forty-five percent of propylene glycol produced is used as chemical feedstock for the production of unsaturated polyester resins. Propylene glycol is used as a humectant, solvent, and preserva-tive in food and for products.
Physical state and appearance: Colorless clear Liquid. (Oily liquid.) Practically Odorless.
Taste: Practically Tasteless.
Molecular Weight: 76.1g/mole
Boiling Point: 188°C (370.4°F)
Melting Point: -59°C (-74.2°F)
Specific Gravity: 1.036 (Water = 1)
Vapor Pressure:0 kPa (@ 20°C) 0.08 mmHg at 20 C 0.129 mmHg at 25 C
Vapor Density: 2.62 (Air = 1)
Water/Oil Dist. Coeff.: The product is more soluble in water; log(oil/water) = -0.9
Dispersion Properties: See solubility in water, acetone
Application:
Its most important end use is in the production of unsaturated polyester resins that, in turn, go into items that effect our daily lives, like water tanks, or our leisure time, like sailing boats. It can also be used as plasticizer, surface active agent, emulsifying agent and demulsifying agent, mould inhibitor, antiseptic for fruit, ice inhibitor and moisture preserving agent for tobacco.
