DIALLYLDIMETHYLAMMONIUM CHLORIDE

'Phase transfer catalysis (PTC)' methodology is a powerful tool improving process efficiency, product selectivity and providing mild reaction conditions in organic chemical reactions. In many chemical reaction situations, there are different species (immiscible liquids or solid and liquid) which don't react each other due to separation by an interface. Small quantity of ‘phase-transfer catalyst’, involves a substrate (soluble in the organic layer) and an anionic reagent or a nucleophile (dissolved in the aqueous layer), extracts one of the reactants, most commonly an anion, across the interface into the other phase where reaction can take place with the substrate and reaction can proceed. The quaternary ammonium salts can carry the nucleophile from the aqueous to organic phase and are used as the most commonly used as phase-transfer catalyst. The phosphonium derivatives favoring higher thermal stability property are also used. Crown ethers and polyethylenglycol compounds are also widely used in this application.

GENERAL DESCRIPTION & APPLICATIONS
Quaternary ammonium compounds are any of a group of ammonium salts in which organic radicals have been substituted for all four hydrogens of the original ammonium cation. They has a central nitrogen atom which is joined to four organic radicals and one acid radical. The organic radicals may be alkyl, aryl, or aralkyl, and the nitrogen can be part of a ring system. They are prepared by treatment of an amine with an alkylating agent. They show a variety of physical, chemical, and biological properties and most compounds are soluble in water and strong electrolytes. In addition to their tendency of locating at the interface of two phases (liquid–liquid or solid–liquid) to introduces continuity between the two different phase, they have properties of disrupting micro-organisms' cell processes. These compounds are used as ; Surface-active agents Solvents Intermediates Active Ingredient for Conditioners Antistatic Agent Detergent Sanitisers Softner for textiles and paper products Phase Transfer Catalyst Antimicrobials Disinfection Agents And Sanitizers Slimicidal Agents Algaecide Emulsifying Agents Pigment Dispersers 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 solid bond, allyl can undergo free radical addition to solid 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.
