DIPROPYLENE GLYCOL MONOMETHYL ETHER
Descriptions
Dipropylene Glycol is a colourless, viscous, practically non-toxic and slightly hygroscopic liquid; melting point -78 C, boiling point 231 C, specific gravity 1.023. It is a isomer mixture of 1,1'-Oxybis(2-propanol) (cas no.108-61-2), 2-(2-Hydroxypropoxy)-1-propanol (106-62-7) and 2,2'-Oxybis(1-propanol) (110-98-5). Dipropylene glycol is miscible in water, alcohols, esters and almost organic solvents and various vegetable oils. It is produced during the manufacture of propylene glycol from propylene oxide along with tripropylene glycol and higher glycols. Dipropylene Glycol is used as a solvent, coupling agent and chemical intermediate. Dipropylene glycol is used as a component in the production of unsaturated polyester resins, alkyd resins, polyurethane polyols, textile auxiliaries and Dibenzoate plasticisers. It is an ingredient of cutting oils, functional fluids, industrial soaps, agricultural insecticidal formulations, defoamers, cosmetics and fragrances. It is used an additive for carburettor fuels as freezing agent. Dipropylene glycol is used as a solvent for printing inks, cellulose acetate, nitrocellulose, lacquers and coatings. In the refinery industry, it is used used as an extraction solvent to extract aromatics.
Applications
Solvent for coating systems; Additive in paint removers; Component in hydraulic fluids. Starting material for the production of esters used as plasticizers. It reacts with acids to form esters, oxidizing agents to form aldehydes or carboxylic acids, alkali metals to form alcoholates or aldehydes to form acetals. Theses properties support the use in agricultural, cosmetic, electronic, ink, textile and adhesive products.
