“…Molybdenum modified materials are active acid catalysts (because of material Lewis acidity enhancement due MoO 3 content [25,26]) and may serve as catalysts in alkane isomerization [27][28][29][30][31]. Usage of molybdenum-based catalyst in α-pinene oxide is also reported [32].…”

Natural source turpentine is an available source of α-pinene oxide. This compound’s value is especially given by the possibility of producing important compounds campholenic aldehyde and trans-carveol. In this work, we would like to present the usage of MoO3-modified zeolite BETA in α-pinene oxide isomerization concerning campholenic aldehyde and trans-carveol formation using a wide range of solvents. Catalyst calcination temperature also influenced the reaction course (selectivity to desired compounds and reaction rate). MoO3-zeolite BETA was prepared by the wet impregnation method and characterized by different techniques. The use of polar aprotic solvents had the most positive effect on the reaction course. Solvent basicity and polarity considerably influenced the reaction rate and selectivity to particular products. The combination of high basicity and the high polarity was the most suitable for the studied reaction from the reaction rate point of view. Selectivity to campholenic aldehyde and trans-carveol was the most influenced by solvent basicity. Higher solvent basicity caused the preferential formation of trans–carveol, influence on selectivity to campholenic aldehyde formation was the opposite. The described catalyst may be used for α-pinene oxide rearrangement to both desired products dependently on the used solvent. Molybdenum offers an exciting alternative for previously described modifications of zeolites for this reaction.

“…Up till now, many methods have been employed to synthesize different morphologies of MoO 2 . MoO 2 powder is traditionally prepared by reducing molybdenum trioxide with hydrogen at high temperature [8,9]. Yang et al synthesized MoO 2 by reduction of MoO 3 with ethanol vapor.…”

“…Of these, MoO 2 , with good electronic conductivity, is a promising anode material, which can incorporate lithium ions into its lattice structure during charge and provides a reversible storage source for lithium ions [13][14][15]. Traditionally, MoO 2 is prepared by reducing MoO 3 with hydrogen at high temperature [16][17][18]. Here we use ethanol vapor as a reducing agent instead of hydrogen, which is much cheaper and safer.…”
