Abstract: A process and a mixture for oxidizing an alkyl-aromatic compound comprises forming a mixture comprising the alkyl-aromatic compound, a solvent, a bromine source, and a catalyst; and contacting the mixture with an oxidizing agent at oxidizing conditions to produce an oxidation product comprising at least one of an aromatic aldehyde, an aromatic alcohol, an aromatic ketone, and an aromatic carboxylic acid. The solvent comprises a carboxylic acid having from 1 to 7 carbon atoms and an ionic liquid selected from the group consisting of an imidazolium ionic liquid, a pyridinium ionic liquid, a phosphonium ionic liquid, a tetra alkyl ammonium ionic liquid, and combinations thereof. The catalyst comprises at least one of cobalt, titanium, manganese, chromium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, and zirconium.

Abstract: A method for drying granulated dielectric materials including superhigh frequency heating of granules which are moved in heating space by a strong hot air flow. The granules are moved at a variable speed, a negative temperature gradient is produced, and humid air is removed from the heating space. According to the invention, the apparatus for drying granulated dielectric materials includes a superhigh frequency generator and a drying chamber which, in turn, has an input waveguide and an output waveguide interconnected by a waveguide elbow. An air inlet and a granules inlet are connected to an input of the input waveguide. The output waveguide has an air separator arranged at its input and a resonator bin arranged at its output.
