Lignoceryl alcohol is a chain-like chemical compound from the group of wax alcohols .

Occurrence

Forest pine ( Pinus sylvestris )

Lignoceryl alcohol occurs in the bark wax of pinaceae and montan wax .

Extraction and presentation

Lignoceryl alcohol can be obtained from lanolin . This is saponified and the wax alcohols extracted with petroleum ether and the individual compounds isolated.

It can also be obtained by reducing lignoceric acid.

properties

Lignoceryl alcohol is a white solid that is practically insoluble in water.

use

Lignoceryl alcohol, like other fatty alcohols, is of great commercial importance as an intermediate due to the large number of reactions that the hydroxy group undergoes.
