Abstract

Higher aliphatic alcohols (C6–C18) are produced in a number of important industrial processes using petroleum-based raw materials, eg, the Ziegler, oxo, and aldol processes. By far the largest volume synthetic alcohol is 2-ethylhexanol, C8H18O, used mainly in production of the poly(vinyl chloride) plasticizer bis(2-ethylhexyl) phthalate, C24H38O4, commonly called dioctyl phthalate or DOP. Other, lower volume synthetic alcohol application areas include solvents and specialty esters.
