APPLICATIONS
|
Allyl- is the
prefix for the univalent organic group, -CH2=CHCH2. Allyl alcohol is
an example, CH2=CHCH2OH, clear, pungent liquid, boiling at 96 C; soluble in
water. It is prepared from allyl chloride by hydrolysis. Allyl compound,
an alkene hydrocarbon, has a vinyl group, CH2=CH-, attached to a methylene -CH2.
Because of the highly reactive double bond, allyl can undergo free radical addition to double bond which
readily combine with themselves or other monomers to form homopolymers or co-polymers
which are used in the production of coatings, adhesives and elastomers. In addition
to free radical addition,
allyl compounds can participate in a wide variety of reactions
including electrophilic additions, allylic substitution
and oxidation. Allyl,
an unsaturated bond, imparts a characteristic
odor in some compounds. An example is allyl
isothiocyanate which is the main ingredient of black mustards.
(white mustard consists principally of
p-hydroxybenzyl isothiocyanate). Allyl
isothiocyanate is called mustard oil.
Allyl esters
are involved in fragrance, flavor, or odor.
Sodium Methallyl Sulfonate
is a co-monomer of the polymers especially for fuctional
acrylic fibers (dying betterment and heat resistance).
It is used in chain transfer agent.
