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
They have properties of disrupting micro-organisms' cell processes and surfactants. These compounds are used as

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 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 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:
