Методика

1000 g of 1-octadecanol (Lorol C18 from Cognis) were initially charged in a stirrable pressure vessel with 10 g of a nickel catalyst (Ni-5249 P from Engelhard; Ni content=63% by weight) and heated to 240° C. Subsequently, over a period of 12 h, hydrogen was added through a sparging tube at a pressure of 20 bar and the reaction gases were simultaneously discharged through a valve in the reactor lid. Thereafter, the product was cooled, discharged and filtered. This reaction product was fractionated in a distillation to give pure heptadecane and then deodorized with nitrogen. This gives a colorless, low-odor product which is liquid at 40° C.
