  • Patent number: 8541626
    Abstract: Ketones may be produced in high yields from glycerides of short chain fatty acids by reaction with a carboxylic acid. The reaction is conducted in the presence of a catalyst and under conditions effective for ketonization of decanoate with the carboxylic acid to produce free ketones. Reaction of a glyceride comprising at least one ester of decanoic acid with a carboxylic acid selected from acetic acid and/or propionic acid produces 2-undecanone and/or 3-dodecanone, respectively. Catalysts of the formula FemCenAlpOx, wherein m is between about 0.2 to about 0.6, n is about 0.2, p is between about 0.6 to about 0.2, and x is greater than 0, produce significantly higher yields of the ketones than other known metal oxides.

  • Patent number: 6316649
    Abstract: Esters of estolides derived from oleic acids and C-6 to C-14 saturated fatty acids are characterized by superior properties for use as lubricant base stocks. These estolides may also be used as lubricants without the need for fortifying additives normally required to improve the lubricating properties of base stocks.

  • Patent number: 6022982
    Abstract: An improved process for the production of high yields of .delta.-lactones and 5-hydroxy fatty acids from unsaturated fatty acids such as oleic acid is disclosed. The .delta.-lactones may be produced by reacting one or more .DELTA..sup.9 to .DELTA..sup.15 unsaturated fatty acids in the presence of an acid catalyst and at a temperature between about 20 to 70.degree. C. Moreover, yields of the .delta.-lactones may be increased even further by reaction in the presence of dipolar, non-participating, non-aqueous solvents. The unsaturated fatty acids may be free or esterified with glycerol or other aliphatic alcohols, and the .delta.-lactones may be produced by reacting mono-, di- or triglycerides of the unsaturated fatty acids with the same catalysts. Because the .delta.-lactones may be produced from the triglycerides of unsaturated fatty acids, the instant process may be practiced using naturally occurring plant oils directly, without the need for any preliminary steps of saponification or steam splitting.
