The present invention is related to a catalytic process, which includes catalytic compositions for depolymerisation and deoxygenation of lignin contained in the biomass for obtaining aromatic hydrocarbons. The catalytic composition consists of at least one non-noble element from group VIIIB of the periodic table supported on a mesoporous matrix composed of an inorganic oxide, which can be alumina surface-modified with a second inorganic oxide with the object of inhibiting the interaction between the active component and the support. The process of lignin depolymerisation consists of dissolving lignin in a mixture of protic liquids, reacting it|a reaction system by batch or in continuous flow at inert and/or reducing atmosphere, at a temperature of between 60 to 320° C. and a pressure of from 5 to 90 kg/cm.sup.2. When the reaction is developed into a batch system, oxygenated aromatic hydrocarbons are mainly produced, both by thermal as well as catalytic depolymerisation, whereas in a continuous flow reaction system, deoxygenated aromatic hydrocarbons are produced.
Acid-catalyzed photocatalyzed oxidation reaction of benzylic C—H bonds of aromatic compound
Provided is a photo-oxidation reaction of benzylic C—H bonds of an aromatic compound under the catalysis of an acid catalyst. The method aims to synthesize aromatic acids and acetophenones. The acid catalyst is one of Bronsted acids, including one or a mixture of two or more selected from the group consisting of hydrochloric acid, phosphoric acid, sulfuric acid, p-toluenesulfonic acid, methanesulfonic acid, trifluoromethanesulfonic acid, trifluoroacetic acid, and potassium hydrogen sulfate, as well as N-propylsulfonate pyridinium hydrogensulfate, N-butylsulfonate pyridinium hydrogensulfate, N-propylsulfonate pyridinium trifluoromethanesulfonate, N-butylsulfonate pyridinium trifluoromethanesulfonate, N-propylsulfonate pyridinium tetrafluoroborate, and N-butylsulfonate pyridinium tetrafluoroborate. The oxidation reaction is conducted under mild conditions (normal temperature and pressure) using air or oxygen as the oxidant in the presence of recyclable catalyst and solvent.

Infusing raw cannabinoids into food oil
A cannabis infused oil is formed by collecting and drying raw cannabis material having a desired cannabinoid profile. Next, the raw dried cannabis material is blended with oil to obtain a cannabis infused oil mixture. Blending is performed without causing the cannabis material to become decarboxylated. Next, the cannabis material is filtered from the cannabis infused oil mixture thereby obtaining a cannabis infused oil. The cannabis infused oil has at least two cannabinoids present in the oil in accordance with the desired cannabinoid profile. Next, the cannabis infused oil is packaged for storage and shipment. The cannabis infused oil is formed without any alcohol, does not have any decarboxylated cannabinoids and is non-psychoactive. In one example, the cannabis infused oil has between 100 milligrams and 2,000 milligrams of cannabinoids per fluid ounce of cannabis infused oil. In another example, before blending with oil, the cannabis material is combined with alcohol.
