- ... Methyl 9(10)-formylstearate was converted to methyl 9(10)-carboxymethylstearate. The reactions to prepare the intermediates methyl 9(10)-hydroxymethyl-, 9(10)-ace toxymethyl-, 9(10)-methylene-, and 9(10)-formylmethylstearate are described. Methyl 9(10)-hydroxy methylstearate readily loses methanol and forms a trimeric polymer. The acetate of the primary alcohol when pyrolyzed gives 59% yield of me ...

- ... Flavor and oxidative stabilities were studied by organoleptic evaluation and chemical analysis of three different samples of soybean oil: unhydrogented (I); hydrogenated with nickel catalyst (II); and hydrogenated with copper-chromium catalyst (III). Analyses for these oils were: I II III iodine Value 138 109 113 Linolenate, % 8.3 3.3 0.4 Each oil was deodorized with the addition of either citric ...
