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.
Methallyl chloride is used as an intermediate for organic synthesis especially for the manufacturing insecticide and fumigant. It is also used in the production of acrylics to improve dying property. It is also used as an intermediate for pharmaceuticals. |
