APPLICATIONS
|
Allyl Pentaerythritol,
containing
allyl bonds in a quaternary mole structure, improves heat resistance, color stability, balance
between toughness
and flexibility radical curing
resins. Allyl group functionality gives the advantage to inhibit oxygenation from surface tackiness in curing
resins. It offers the application in;
- Link
between organic and inorganic chemistry
- Crosslinker
for radical polymerisation
- Polyurethane resins
- Unsaturated
polyesters
- Thickeners
- Epoxy resins
- Superabsorbant
polymers;

GENERAL
DESCRIPTION OF PENTAERYTHRITOL
|
Pentaerythritol
(also called Tetramethylolmethane) is a polyalcohol
compound containing 4 esterficable hydroxyl groups
which characterize polyol functions. Almost infinite esters are
available from polyol. Polyol is essential in polyurethane
production. Pentaerythritol is a white crystalline odorless
solid; moderately soluble in cold water, freely soluble in hot
water; melting point 260
C and boiling point 276 C at 30 mm Hg. It is prepared
from aldol
condensations of formaldehyde and acetaldehyde. and followed Cannizaro reaction.
It is used to make explosives such
as pentaerythritol tetranitrate (PETN). PETN, also known as penthrite, is
a white crystalline compound;
melting point 139 C; explodes at 205-215C; soluble in acetone, insoluble in water. Pentolite is
a highly reactive explosive composed of
pentaerythritol and trinitrotoluene.
Pentaerythritol is a basic material for polymer production.
It
is used to make alkyol resins, other coating compounds.
Pentacite
obtained from pentaerythritol is
an alkyd resin used in coatings and printing inks.
Pentaerythritol is used in the preparation of polyvinyl
chloride stabilizers, antioxidants, varnishes, paints, adhesives, and
other infinite derivatives. There are commercially three grades of pentaerythritol: mono ( 98 percent, with
di- and tripentaerythritol impurities), technical (88 percent, with 8 to 10
percent dipentaerythritol, balance tri-) and nitration (99 percent, with
di- and tripentaerythritol impurities).
