  • Oligomerization of jojoba oil in super-critical COfor different applications
    Patent number: 8742148
    Abstract: Dimers of jojoba oil wax esters are prepared by reacting the wax esters in the presence of a catalytically effective amount of an acid catalyst in supercritical CO2. In the reaction, the double bonds of the wax esters are opened and cross link or polymerize two wax esters as dimers. The jojoba ester dimers which are produced are of the formula: wherein R1 and R1? are independently selected from the group consisting of C15-C23 monounsaturated hydrocarbons, R2 and R2? are independently selected from the group consisting of C8-C14 saturated hydrocarbons, and R3 and R3? are independently selected from the group consisting of C6-C8 saturated hydrocarbons.
