实验步骤: A mixture of plant oils (linseed, soybean, and rapeseed oils) was pretreated by hydrolysis and distillation to obtain tatty acid fractions according to carbon numbers. The C18 acid fraction thus obtained was used as the feed, the fraction being diluted with a paraffinic diesel fuel of biological origin. C18 acid content of the feedstock thus obtained was 31%, by weight. Double bonds of the feedstock were selectively prehydrogenated, and the stearic acid was continuously ketonised at atmospheric pressure, in a tubular reactor using a MnO2 catalyst. Temperature of the reactor was 370° C., the WHSV of total feed being 3 l/h. 22% by weight of 18-pentatriacontanone, or stearone, in a diluent was obtained as the ketonisation product. was 370° C.

实验步骤: 18-Hydroxypentatriacontane was prepared as follows and used without further purification. In a dry flask charged with argon was prepared a solution of lithium aluminum hydride (0.75 g, (19.8 mmol)) in freshly distilled tetrahydrofuran (400 mL). To this solution was added stearone (5.0 g, (9.9 mmol)). The reaction mixture was slowly brought to reflux (and allowed to stir at reflux overnight). After cooling to room temperature, the remaining lithium aluminum hydride was quenched by the dropwise addition of water (0.76 mL), followed by 15% NaOH (0.76 mL), and water again (2.2 mL). The reaction mixture was allowed to stir for 1 hour. The solvent was evaporated, and the resulting solids were triturated with hot toluene (300 mL). The toluene was evaporated to yield the desired alcohol (4.9 g. 97%). 1H NMR (300 MHz, CDCl3, TMS=0), δ 3.58 (m, 1H), 1.38 (m, 4H), 1.25 (bs, 60H), 0.88 (t, 6H, J=6.5). used without further purification In a dry flask charged with argon to reflux the remaining lithium aluminum hydride was quenched by the dropwise addition of water (0.76 mL) to stir for 1 hour The solvent was evaporated the resulting solids were triturated with hot toluene (300 mL) The toluene was evaporated
