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.
Dipropylene Glycol is a colourless, viscous, practically non-toxic
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)
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,
polyols, textile auxiliaries and
It is an ingredient of cutting oils,
soaps, agricultural insecticidal formulations, defoamers, cosmetics
It is used an additive for carburettor fuels as
a lubricant and anti-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.
