Structural isomers of linoleic acid from vegetable oils by homogeneous rhodium catalysis

A range of vegetable oils (peanut, corn, soybean, safflower, and linseed) dissolved in ethanol have been subjected to isomerisation by reaction with [RhCl(C 8 H 14 ) 2 ] 2 (where C 8 H 14 represents cyclo-octene) and SnCl 2 at 608C for 24 h. Under these conditions methyl linoleate and linolenate gave products with 87 and 92% conjugated unsaturation respectively. In contrast to the alkaliisomerisation process used to produce CLA, the product with the rhodium catalyst is present as triacylglycerol rather than free acid. In a typical result for soybean oil the level of linoleic acid falls from 55.6 to 3.2% and the CLA produced consists of the 9c11t and 10t12c isomers (89.1%) along with 9t11t (8.6%) and 9c11c (2.3%).

Thinking clearly about biofuels: developing better performance metrics It is argued that the "net energy" debate about biofuels is irrelevant and that better performance metrics must be developed. For example, only 1MJ of electricity is produced for 3MJ of coal burned but it is not suggested that we
