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.
