Catalytic Hydrodeoxygenation of Anisole

Feliczak-Guzik, et al. Catalysis Today, 2020, 354, 67-76.

Anisole contains an isolated methoxy group (-OCH3), which is the most common group in the chemical structure of bio-oils. Catalytic hydrodeoxygenation (HDO) reactions are a promising approach to obtain high-quality hydrocarbon fuels from bio-oils. The hydrodeoxygenation of anisole can be achieved by depositing a ruthenium-SBA-12 silica catalyst.
Hydrodeoxygenation of anisole
· An appropriate amount of the catalyst (0.025, 0.05 or 0.1 g) together with anisole (1 g) was placed in a glass vessel equipped with a magnetic stirrer.
· The glass vessel with the reaction mixture was placed in a high-pressure reactor, which was tightly closed and flushed with argon of N5.0 purity in order to remove air from the reactor.
· Then hydrogen of N5.0 purity was introduced to the reactor and then the reactor was filled with hydrogen up to the pressure of 25, 40 or 60 bar.
· The reaction was conducted at three temperatures 90, 110 or 130 °C, for the time of 1, 2.5 or 4 h. The reaction mixture was stirred at 700 rotations per minute.
· After the reaction time, the reaction mixture was centrifuged in order to separate the liquid reaction products from the solid catalyst.
