- Abstract:
- Oils and fats are the most important renewable raw materials for the
chemical industry. Hitherto, industrial oleochemistry has concentrated
predominantly on the carboxy functionality of fatty acids but, more recently,
modern synthetic methods have been applied extensively to fatty compounds for
the selective functionalization of the alkyl chain. Radical, electrophilic,
nucleophilic, and pericyclic as well as transition metal catalyzed additions
to the C-C double bond of, for example, oleic acid as the prototype of a
readily accessible, unsaturated fatty acid have led to a large number of novel
fatty compounds from which interesting properties are expected.
Functionalization of C-H bonds in the alkyl chain is also feasible with
remarkable selectivity. Effective and highly versatile catalysts for the
metathesis of esters of unsaturated fatty acids have been developed, which
lead to new and interesting -unsaturated fatty acids. The epoxidation of
unsaturated fatty acids has been developed extensively. Enzymatic reactions
allow syntheses with high selectivity and yield of mono- and diglycerides and
esters of carbohydrates with a variety of surfactant properties. Regio- and
enantioselective microbial hydrations and hydroxylations widen the spectrum of
selective reactions. Of considerable significance is that, with the use of
gene technology, natural oils and fats have been improved significantly and
will be improved still further, insofar as they show a more uniform and often
unusual fatty acid spectrum. Numerous fatty acids are now available in a
purity which makes them attractive for synthesis and as raw materials for the
chemical industry.
