Documented Uses

• Used in plasticizers and in organic synthesis; Also used in resin solvents, emulsifiers, and antifoaming agents; [Hawley]
• Plastic Composites Manufacturing [Category: Industry]
• Ingredient of plasticizers, intermediate for nonionic detergents and surfactants, synthetic drying oils, cutting and lubricating oils, hydraulic fluids; resin solvents; emulsifiers; antifoaming agent; intermediate for introducing the isooctyl group into other cmpd.
• Branched C16 alcohols, also known as isohexadecyl alcohol or C16 oxo alcohols, are prepared by the oxo process and by aldol-like condensation of isooctyl alcohol and subsequent hydrogenation.
• The principal use of these alcohols is in preparing plasticizers, mainly diisoctyl phthalate, but also esters of adipic, sebacic, azelaic, and trimellitic acids. Isooctyl alcohol is also used as a solvent for fats, oils, and waxes, as well as various rubber formulations ...
• Isooctyl alcohols or isooctanols are ... made by the oxo process in which heptenes are reacted with carbon monoxide and hydrogen in the presence of a catalyst, followed by hydrogenation.
