Chemical properties Tripropylene glycol is a colorless to light yellow liquid at room temperature and pressure. It has certain solubility in water and is easily soluble in common organic solvents. It has the characteristics of low toxicity, low vapor pressure and medium viscosity. It is a kind of raw material which can be used in various irradiation Chemicalbook curing formulations. It is usually esterified with acrylic acid to produce tripropylene glycol diacrylate. Tripropylene glycol can be used as raw material in various irradiation curing formulations, irradiation curing for printing inks, varnishes, paints and coatings. Tripropylene glycol is usually synthesized by propylene oxide hydrolysis or propylene glycol catalytic dehydrating. Its unique chemical and physical properties provide strong support for its application in organic synthesis, cosmetics, medicine, coatings and other fields. Tripropylene glycol is a kind of raw material for preparation of irradiation curing reagent, which has the characteristics of low toxicity, low vapor pressure and medium viscosity. It is usually esterified with acrylic acid to form tripropanediol diacrylate, which is an important raw material in the rapidly developing irradiation curing industry.
