n-Heptadecane synthesis

13synthesis methods
Gas-phase dehydrogenation of n-alkanes over noble-metal catalysts yield the corresponding n-alkenes at low conversion rates (ca. 10%) with predominantly internal double bonds. The corresponding alkenes can be isolated in high purity by selective molecular-sieve processes.

Yield:629-78-7 97.3%

Reaction Conditions:

with hydrogen in cyclohexane at 300; under 22502.3 Torr; for 6 h;

Steps:

2.3. Catalytic deoxygenation

General procedure: The catalytic deoxygenation of MO, JO and WCO using fresh NiCeAlcatalysts were conducted using a stirred batch reactor [YZPR-100(M),YanZheng Instrument, Shanghai, China] with a maximum operatingpressure of 15 MPa at 400 . In each experiment, after the reactor waspurged with pure N2 at least 3 times at room temperature, 0.1 g catalystand 1 g reactant were introduced into the reactor which then was slowlyheated to reaction temperature (300 ). Then 2.5 MPa H2 was introducedto initiate the catalytic deoxygenation reaction for 6 h. In order toreduce the error and contingency during test, all experiments wererepeated at least three times to ensure the accuracy of the data. Recyclabilitytest and deoxygenation experiments using fresh, spent and regenerated NiCeAl-3.0 were also performed at the same conditiondescribed above
