Terminalia belerica Roxb. seed oil: a potential biodiesel resource.

Terminalia belerica seeds, collected from Indian forests, were explored as an alternate bioresource for biodiesel synthesis. The oil yield of T. belerica seed is about 31% (dry weight basis).

Studies on Guizotia abyssinica L. oil: biodiesel synthesis and process optimization.

Guizotia abyssinica seeds, a common bird feedstock, have been explored for the potential of biodiesel synthesis. The oil was extracted from the seeds by solvent extraction and composition of G. abyssinica oil was examined.

Biodiesel surrogates: achieving performance demands.

Synthesis of surrogate molecules is particularly useful for generating in sight of structural-activity relationships, understanding processes and improving the performance. In order to improve upon the physico-chemical properties of biodiesel, methyl, ethyl, isopropyl and n-butyl esters of beta-branched fatty acid have been synthesized, initiating from beta-branched alcohols. Beta-branched alcohols upon oxidation gave corresponding acids, which were converted to their esters.
