実験手順: Approximately 360 g of the 1,2-mixed pentadecanedioloctadecanediol (obtained from Viking Chemical Co. as Vikol 158 containing about 28% 1,2-pentadecanediol, about 28% 1,2-hexadecanediol, about 28% 1,2-heptadecanediol and about 16% 1,2-octadecanediol) were charged to a glass reactor equipped with heater, agitator, Dean-Stark tube with condenser and provision for blanketing the vapor space with nitrogen. The contents were heated to 70° C. to liquify and 55 g of dimethyl hydrogen phosphite were slowly added. The reaction mixture was heated to 110° C. and held for 2 hours, held at 120° C. for 1 hour, and held at 130° C. for 1 hour. During this reaction period, methanol distilled over and condensed into the trap. The crude product was vacuum stripped at 150° C. to remove volatile materials. 379 g of finished additive were produced. The product was an amber fluid which became waxy on cooling. equipped with heater, agitator, Dean-Stark tube with condenser The reaction mixture was heated to 110° C. held at 120° C. for 1 hour held at 130° C. for 1 hour distilled over and condensed into the trap stripped at 150° C. to remove volatile materials 379 g of finished additive were produced on cooling

実験手順: The bioconversion of 1,2-hexadecanediol was tested following the procedures set forth in Example 24. This substrate was tested to demonstrate the ability to form a (ω,ω-1)-dihydroxy fatty acid. Recovery was 0.138 g from 0.253 g starting material (54.5% recovery). NMR shows the 1,2-diol to be unchanged, as expected from olefin studies. But, interestingly, CH3 oxidation to the 15,16-dihydroxyhexadecanoic acid was lower than seen with octadecene, because the starting material was solid. Conversion was only about 30%. Some fatty unsaturation and minor polypropylene glycol were also seen. Since the NMR results were fairly convincing, no GC/MS analysis was performed. Since the NMR results
