Tetradecane synthesis

13synthesis methods
Tetradecane is isolated from kerosene and gas oil fractions of crude oil by selective adsorption followed by fractional distillation.

Yield:629-50-5 89% ,629-59-4 2.1%

Reaction Conditions:

with hydrogen;Ni-2549 P at 240; under 15001.5 Torr; for 12 h;

Steps:

1

1000 grams of 1-tetradecanol (4.7 mol; Lorol C 14 from Cognis) were introduced into a stirrable pressure vessel with 10 grams of a nickel catalyst (Ni-5249 P from Engelhard; Ni content=63% by weight) and heated to 240° C. Hydrogen was then added over a period of 12 hours under a pressure of 20 bar through a gas dispersion tube and, at the same time, the reaction gases were removed through a valve in the lid of the reactor. The product was then cooled, drained off and filtered. A yield of 845 grams of reaction product was obtained.GC analysis revealed the following composition: 89.0% tridecane, 2.1% tetradecane, 4.1% 1-tetradecanol, 4.2% dimeric reaction products.The reaction product was then fractionated by distillation to pure tridecane and deodorized with nitrogen. A colorless, thinly liquid and substantially odorless product was obtained.
