Understanding Partial Differential Equations: Types and Solution Methods
Definitions of inorganic chemistry
1.
2.
3. Also called neutral spirit.
It is a mixture of
Ethanol (95.6%) w/v
Water
produced as an azeotrope (a constant
boiling mixture) by distillation.
It is produced from molasses.
It is a highly concentrated ethanol
that has been purified by means of
repeated distillation in a process
called rectification.
4. Also called Denatured Alcohol or
Wood spirit.
It is a mixture of 95% w/v Ethyl
alcohol and 5-10 % Methanol
(CH3OH) .
Methanol is added to prevent
methylated spirit being used as cheap
alcohol.
In case of methanol poisoning,
Ethanol may be administered as an
antidote.
6. It is the ethanol containing
less than 1% of water.
At least 99% pure alcohol by
weight.
Uses – As a reagent in
organic chemistry and
chromatography.
Used in rubbing compounds,
lotions, tonics, colognes), in
perfumery.
As a germicide (to kill mos),
an antifreeze, a fuel.
Editor's Notes
w/v – 95.6 % of ethanol is present in every 100 ml of rectified spirit.
