GENERAL
DESCRIPTION |
Acetylsalicylic
Acid, also known by trade name Aspirin, is an acetyl derivative
of salicylic acid that is a white, crystalline, weakly acidic
substance, with melting point 137°C. It is useful in the relief
of headache and muscle and joint aches. Aspirin is also effective
in reducing fever, inflammation, and swelling and thus has been
used for treatment of rheumatoid arthritis, rheumatic fever,
and mild infection. Large doses cause acid-base imbalance and
respiratory disturbances and can be fatal, especially in children.
Acetaminophen (known by trade name Tylenol), which does not
cause gastric irritation but does lower fever and relieve pain,
is often substituted for Aspirin. |

GENERAL
DESCRIPTION OF SALICYLIC ACID |
Salicylic
Acid is a white crystalline powder or needle-shaped crystals
with sweetish taste; soluble in acetone, ether, alcohol, boiling
water, benzene and turpentine, sparingly soluble in chloroformbenzene,
slightly soluble in water; melts at 158 C. It is prepared commercially
by sodium salicylate which derived from sodium phenolate with
carbon dioxide under heating and pressure. It contains both
a hydroxyl and a carboxyl group, which react with either an
acid or an alcohol. The carboxyl group forms esters with alcohols;
e.g. methyl salicylate is formed with methanol, which used in
food flavorings and preservatives; menthyl salicylate is formed
with methanol, which is used in suntan lotions; phenyl salicylate
(called salol) is formed with phenol, which is used as an antiseptic
and antipyretic agent. The hydroxyl group reacts with acetic
acid to form acetylsalicylic acid (called aspirin). Salicylic
Acid is important for the preparation of other pharmaceutical
products, dyes, flavours, and preservatives. The sodium salt
(Sodium salicylate), a shiny white powder, is used for antiseptics
preparations and as a preservative. Salicylic Acid derivatives
are used in formulating flavors, preservatives and UV
absorbers for food and cosmetics as well as plastics. They are
used in manufacturing pharmaceuticals mainly analgestics and
antipyretics for the relief of pain and fever. |
