Phenol
Phenol is any of a family of organic compounds
characteristic by attachment of at least one hydroxyl
group to a carbon atom which forms part of the benzene
ring. Phenol is also called carbolic acid or
hydroxybenzene.
In 1834, a German named Ruge isolated carbolic acid from
coal tar. In 1843, another German, Gerhardt, prepared
the same substance by a different method and called it
phenol. In 1845, an English surgeon, Joseph Lister,
began to use a dilute solution of phenol to treat
wounds, establishing its usage as an antiseptic.
