1,6-Hexanediol is an organic compound with the formula (CH2CH2CH2OH)2. It is a colorless water-soluble solid.
Production
1,6-Hexanediol is prepared by the hydrogenation of adipic acid or its esters. Laboratory preparation could be achieved by reduction of adipates with lithium aluminium hydride, although this method is impractical on a commercial scale.
Properties
As 1,6-hexanediol contains the hydroxyl group, it undergoes the typical chemical reactions of alcohols such as dehydration, substitution, esterification.
Dehydration of 1,6-hexanediol gives oxepane, 2-methyltetrahydropyran and 2-ethyltetrahydrofuran. Corresponding thiophene and pyrrolidone can be made by reacting 1,6-hexanediol with hydrogen sulfide and ammonia respectively.
Uses
1,6-Hexanediol is widely used for industrial polyester and polyurethane production.
1,6-Hexanediol can improve the hardness and flexibility of polyesters as it contains a fairly long hydrocarbon chain.

GENERAL DESCRIPTION: Diols contribute to high water solubility, hygroscopicity and reactivity with many organic compounds, on usually linear and aliphatic carbon chain. 1,6-Hexanediol, linear diol containing two primary hydroxyl groups at terminal locations for reaction of di-substitution, is used as an intermediate in polymer syntheses (nylon, polyesters manufacturing). The main application field is polyurethanes manufacturing. It is also used in gasoline refining and in pharmaceutical manufacturing. 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.

1,6-Hexanediol (HDO) is an important precursor in the polymer industry. The current industrial route to produce 1,6-Hexanediol involves energy intensive and hazardous multistage (four-pot–four-step) chemical reactions using cyclohexane (CH) as the starting material, which leads to serious environmental problems. Here, we report the development of a biocatalytic cascade process for the biotransformation of CH to 1,6-Hexanediol under mild conditions in a one-pot–one-step manner. This cascade biocatalysis operates by using a microbial consortium composed of three E. coli cell modules, each containing the necessary enzymes. The cell modules with assigned functions were engineered in parallel, followed by combination to construct E. coli consortia for use in biotransformations. The engineered E. coli consortia, which contained the corresponding cell modules, efficiently converted not only CH or cyclohexanol to 1,6-Hexanediol, but also other cycloalkanes or cycloalkanols to related dihydric alcohols. In conclusion, the newly developed biocatalytic process provides a promising alternative to the current industrial process for manufacturing 1,6-Hexanediol and related dihydric alcohols.
