Detailed Product Description:
A colorless, odorless, nearly tasteless syrupy liquid. Hygroscopic.
Soluble in water, alcohol, acetone and most organic solvents. Often
used as a non-toxic replacement for ethylene glycol in coolants and
automotive antifreezes. Also used as a solvent for fats, oils, waxes,
perfumes and colognes, hydraulic fluids, bactericides, and deicing fluids
for aircraft and runways.
Grade/Purity:
This is Electrolytic Grade material with minimum purity of 99.8%.
Background:
Propylene glycol contains an asymmetrical carbon atom, so it exists in
two stereoisomers. The commercial product is a racemic mixture. Pure
optical isomers can be obtained by hydration of optically pure propylene
oxide.
This compound is sometimes called á-propylene glycol to distinguish it
from the isomer propane-1,3-diol HO-(CH2)3-OH, also called â-propylene
glycol.
Propylene glycol, also called 1,2-propanediol or propane-1,2-diol, is
an organic compound (a diol or double alcohol). It is a colorless, nearly
odorless, clear, viscous liquid with a faintly sweet taste, hygroscopic and
miscible with water, acetone, and chloroform.
Production:
Industrially propylene glycol is produced from propylene oxide. Different
manufacturers use either a non-catalytic high-temperature process or a
catalytic method, which proceeds at a lower temperature in the presence
of an ion exchange resin or a small amount of sulfuric acid or alkali.
Final products contain 20% 1,2-propanediol, 1.5% of dipropylene glycol and
small amounts of other polypropylene glycols. Propylene glycol can also be
converted from glycerol, a biodiesel byproduct
Precautions:
Combustible. May cause slight skin irritation with chronic exposure.
Relatively non-toxic substitute for ethylene glycol.
