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

GENERAL
DESCRIPTION OF PHASE TRANSFER CATALYSIS
|
|
'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 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
