BENZYLTRIMETHYLAMMONIUM CHLORIDE (TRIMETHYLBENZYLAMMONIUM 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 othrer due to separattion 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 widelt 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. Such compounds include Benzalkonium Chloride ( CAS RN: 8001-54-5) Benzethonium Chloride CAS 121-54-0 Cetalkonium Chloride( CAS 122-18-9) Cetrimide ( CAS 8044-71-1) Cetrimonium Bromide ( CAS 57-09-0) Cetylpyridinium Chloride (CAS 123-03-5) Stearalkonium Chloride ( CAS 122-19-0) They have properties of disrupting micro-organisms' cell processes and surfactants. These compounds are used as 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

GENERAL DESCRIPTION OF DISINFECTANT
Disinfectant is an agent applied to inanimate objects to destroy, neutralize, or inhibit the growth of disease-carrying microorganisms, (whereas antiseptics are applied primarily to living things). Heat and radiation are also disinfectants. Common ingredients of chemical disinfectant are: Mercuric Chlorides Formaldehyde 8-Hydroxyquinoline Copper Hydroxide Cresols Alcohols (Ethyl Alcohol; Isopropyl Alcohol) Iodines / Iodophors Chlorine releasing compounds Gluteraldehyde Phenolics Quaternary Ammonium Compounds
