Oleic alcohol

The activities of the immobilized lipase components in ester synthesis have also been tested. Myristic acid was esterified with propanol, isopropanol, and oleic alcohol, respectively (Table X). 

Even though the immobilized Lipase B has lew activity in acidolysis, it is quite active in ester synthesis with short-chain alcohols where it seems to be responsible for the abilities shewn by the crude enzyme. Lipase B functions almost equally well on 1-propanol and 2-propanol but for the long-chain alcohol, oleic alcohol, Lipase B has somewhat lower activity, and Lipase A seems to contribute the activity observed for the crude enzyme. 

It is interesting to note, however, that a polymer foam of sufficient durability could be produced even at high surfactant concentrations if, for example, a formulation of polymerising surfactant such as sodium co-acrylamidoundecanate or oleic alcohol is used [134]. This can be realised only in the region of the phase diagram corresponding to the existence of a lamellar liquid-crystalline structure.

Other 0X0 reactions of unsaturated functional derivatives (acrylic acid or acrylic esters, polyisobutenes, oleic alcohol, high-molecular fatty acids, etc.) have been described [128, 129, 139-141, 143, 144, 208, 218 h, 236]. 

Supported aqueous phase catalysts were developed for hydroformylation by Davis and co-workers [67]. Very hydrophobic alkenes,such as 1-octene, 1-tetra-decene, or 1-heptadecene and also oleic alcohol, were hydroformylated using...

Besides acids and esters, the corresponding unsaturated long-chain alcohols have also been subjected to the addition of syngas [52]. For example, the hydroformylation of oleic alcohol, in which the substrates can be prepared by heterogeneous hydrogenation of oleic acid esters [53] using a sulfonated triphenylphosphine as a ligand under neat conditions, has been described in a patent of Ruhrchemie (Scheme 6.96) [54].

Less important than saturated alcohols, the most common ones are allyl alcohol C3H5OH and oleic alcohol CigH340H. They have no action on aluminium.
