Local: Diols contribute to high water solubility, hygroscopicity and
reactivity with many organic compounds, on usually linear and aliphatic carbon
chain. 1,2-Octanediol,
linear diol containing two primary hydroxyl groups,
has bacteriostatic and bacteriacidal properties which
are useful in cosmetics as a
preservative. It is also used in coating materials, slurries, paper mills and
water circulation systems for the effective preservation against bacteria and
fungi. It is used as an emollient, humectant, and wetting agent in cosmetic
and skin care products. Alcohols are
very weak acids as they lose H+ in the hydroxyl group. Alcohols undergoes
dehydration reaction which means the elimination of water molecule replaced by
a pi bond between two adjacent carbon atoms to form alkenes under heating in the
presence of strong acids like hydrocloric acid or phosphoric acid. Primary and
secondary alcohols can be oxidized to aldehydes and ketones respectively.
Carboxylic acids are obtained from oxidation of aldehydes. Oxidation in organic
chemistry can be considered to be the loss of hydrogen or gain of oxygen and
reduction to gain hydrogen or loss of oxygen. Tertiary alcohols do not react to
give oxidation products as they have no H attached to the alcohol carbon.
Alcohols undergoes important reactions called nucleophilic substitution in which
an electron donor replaces a leaving group, generally conjugate bases of strong
acids, as a covalent substitute of some atom. One of important reaction of
alcohol is condensation. Ethers are formed by the condensation of two alcohols
by heating with sulfuric acid; the reaction is one of dehydration. Almost
infinite esters are formed through condensation reaction called esterification
between carboxylic acid and alcohol, which produces water. Alcohols are
important solvents and chemical raw materials. Alcohols are intermediates for
the production of target compounds, such as pharmaceuticals, veterinary medicines,
plasticizers, surfactants, lubricants, ore floatation
agents, pesticides, hydraulic fluids, and detergents.
