| Description |
For widening the scope of utilization of jojoba oil as a
.lubricant, modification of some of its properties depending
upon end-use applications is essential. While some of the
properties can be improved by the addition of suitable
additives, commercially available pour point depresents have
little effect on the pour point of jojoba oil. Chemical
transformation of jojoba oil involving lransesterification
with a !:mitable fatty alcohol or fatty acid seems to be an
attractive route for achieving this goal. Further, because
of the non-availability of jojoba oil on a commercial scale
1n India, .certain non-edible and under exploited vegetable
(triglyceride) oils can also b(~ converted into jojoba oil
equivalents (analogues) by this approach. Long chain
unsaturated fatty alcohols or fatty acids and glycerol,
released as a byproduct depending upon the starting materials
used, are also valuable industrial raw materials.
Reaction conditions for transesterification have been
optimized us1ng model compounds. The desired jojoba
estolides were then synthesised using appropriate unsaturated
2
fatty acid or fatty alcohol. Jojoba analogues have been
~
prepared using triglyceride oil!'>and appropriate alcohol as
starting materials. Jojoba estolides and analogues, with
improvement in pour points varYlng from 6 to 24°C and 3 to
6°C respectively, have been obtained.
