Local:
The future of 2-ETHYLHEXYL ALCOHOL (2-EH) is tied to strength in phthalates. DOP,  the largest volume phthalate ester, is expected to remain flat or decline slightly  due to competition from other phthalates and environmental pressures.  Substitutions by non-phthalates in niche markets and the challenge of  metallocene plastomers, are viewed as possible future threats. Modest growth is  projected for 2-EH-based intermediates for acrylic surface coatings, diesel fuel  and lube additives.
Applications of 2-EH: Plasticizers(dioctyl phthalate, dioctyl adipate,trioctyl trimellitate, dioctyl  terephthalate,), 2-ethylhexyl acrylate, 2-ethylhexyl nitrate (cetane improver), lube  additive, surfactants, solvent, mining applications.
General Description of Alcohol:
Alcohols are widely used as solvents, fuels and chemical raw materials. Generally, hydroxyl group compounds are polar, which trends to promote solubility in water. But the carbon chain resist to solubility in water. Short chain alcohols (methanol, ethanol, and propanol) in which the hydroxyl group predominates are miscible in water. Butanol is moderately soluble because of the balance between the two opposing solubility trends. Higher alcohols are practically insoluble in water because of the hydrocarbon chain's trend is stronger. Alcohols are "protic" solvents. Protic refers to a hydrogen atom attached to an electronegative atom, oxygen. Polar protic solvents are compounds that can be represented by the general formula ROH of which water (H2O), methanol (CH3OH) and acetic acid (CH3COOH) are examples. Water-soluble alcohols, low-molecular weight products, are solvents for the manufacture of coatings, dyes and inks, plastics, flavorings, personal-care products, pharmaceuticals, and cleaners. The higher alcohols, slightly soluble in water or insoluble, can provide the proper balance of target properties when solvent-based solvents are formulated for desired viscosity, flowing and leveling, and curing rate and can be used as coupling agents in waterborne coatings.
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.
Carbinol is a primary alcohol with general formula RCH
2OH. In carbinol nomenclature system, the term of carbinol is methanol itself and other groups are considered to have replaced one of the methanol hydrogen atoms to describe larger alcohols as derivatives of carbinol. This nomenclature system is particularly useful when the groups attached to the methanol carbon are large, aromatic, and cyclo groups. Benzyl alcohol is called phenylcarbinol or benzenecarbinol while benzyl carbinol is phenylethyl alcohol.
