Methods for gas-phase deoxygenation of a bio-oil are provided. In embodiments, such a method comprises exposing a bio-oil vapor comprising hydrocarbon compounds having oxygenated aromatic groups, to hydrogen gas in the presence of catalyst under conditions to induce deoxygenation of the oxygenated aromatic groups to provide a deoxygenated aromatic species, wherein the catalyst is a transition metal-incorporated mesoporous silicate having platinum deposited thereon and the transition metal is selected from Nb, W, Zr, and combinations thereof. The transition metal-incorporated mesoporous silicate catalysts are also provided.

Processes of producing cresols from a phenols containing feed are described. The processes involve a combination of dealkylation and transalkylation processes. The dealkylation process converts the heavy alkylphenols in an alkylphenols stream to phenol and olefins. The olefins produced in the dealkylation process are separated out. The methylphenols, which are not converted in the dealkylation process, and phenol react in the transalkylation process to generate cresols.

The present disclosure relates to cannabigerol sulfonate esters and processes for their use to prepare cannabigerol (CBG) and related compounds, including cannabigerobutol (CBGB), cannabigerovarin (CBGV), and cannabigerophorbol (CBGP). In a preferred embodiment, the cannabigerol sulfonate ester is (E)-4-(3, 7-5 dimethylocta-2,6-dienyl)-3,5-bis(trimethylsilyloxy)phenylromethanesulfonate. In a preferred process, the trifluoromethansulfonate leaving group is replaced by an alkyl group. The disclosure also relates to the use of catalysts and catalytic processes for the preparation of cannabigerol and related compounds from the cannabigerol sulfonate esters.
