Caustic oxidation has been used to convert the complex residue from the isotridecyl alcohol process (“C 13 oxo bottoms”) to simpler mixtures of highly branched, liquid carboxylic acids in about 65% combined yield. One of the products, produced in 34% yield, was a mixture of isotridecanoic acids formed mainly from C 13 alcohol and its ester. It was composed of 85% primary carboxylic acids and 15% secondary. The high boiling acids were largely C 26 secondary car‐boxylic acids formed by oxidation of aldol dimers. The relative rates of esterification were stearic:C 13 acid:high boiling acids—1:0.35: 0.05. In addition, a 22% combined yield of neutrals consisting of saturated and unsaturated hydrocarbons and ethers was obtained.
