Alcohol isooctyl

Plasticizer Range Alcohols. Commercial products from the family of 6—11 carbon alcohols that make up the plasticizer range are available both as commercially pure single carbon chain materials and as complex isomeric mixtures. Commercial descriptions of plasticizer range alcohols are rather confusing, but in general a commercially pure material is called "-anol," and the mixtures are called "-yl alcohol" or "iso...yl alcohol." For example, 2-ethyIhexanol [104-76-7] and 4-methyl-2-pentanol [108-11-2] are single materials whereas isooctyl alcohol [68526-83-0] is a complex mixture of branched hexanols and heptanols. Another commercial product contains linear alcohols of mixed 6-, 8-, and 10-carbon chains.

Toxicology. Isooctyl alcohol is a mucous membrane irritant and central nervous system depressant in animals. 

The 2003 ACGIH threshold limit value-time-weighted average (TLV-TWA) for isooctyl alcohol is 50ppm (266mg/m ) with a notation for skin absorption.

Heptenes. Heptenes, C7FL 7, are used for the preparation of isooctyl alcohol [26952-21-6] by hydroformylation (see Oxo process). The heptenes are prepared by very carefully controlled fractionation of polymer gasoline. Specifications generally call for >99.9% C content (including some paraffin that is also formed) to simplify processing. 

The discovery of the oxo (or more accurately, hydroformylation) process was by Ruhrchemie s Roelen who applied for a German patent in 1938. This turned out to be a breakthrough method for both higher and lower alcohols production from the aldehydes. Exploitation of the process, however, was delayed by World War II. It was not until 19 8 that commercialization occurred with the manufacture of isooctyl alcohol by Enjay Chemical Company (1 ). 

The oxo process was commercialized by Exxon Chemical Co. in the U.S. in 1948 with the manufacture of isooctyl alcohol(7). This...
