The invention relates to a process for removal of bromine, bromine- and/or iodine-containing silicon compounds from compositions of chlorosilanes containing bromine, bromine- and/or iodine-containing silicon compounds, wherein the composition is subjected to a nonthermal plasma and subsequently the chlorosilanes may be separated from the bromine- and/or iodine-containing compounds present by distillation.

A new type of burning device for producing hydrohalogen compounds.

A tube in tube continuous glass lined metal reactor includes: concentric tubular segments; (a) outer glass lined tube and (b) an inner glass lined segment disposed in the outer glass lined tube, defining thereby an intermediate glass lined region between the inner segment and the outer tube.

Disclosed are a large-scale composite synthesis system, a reactor therefor, and a synthesis method using the same, wherein two or more different samples are vaporized in respective vaporizers, and are then fed into a reactor that has a relatively large transverse cross-sectional diameter compared to the connector for transporting the samples in a gas phase and is maintained at a temperature lower than that of the connector, thus producing a powder composite, the composite being synthesized while being electrostatically attached to an adherend surface.

A reaction system and method for preparing compounds or intermediates from solid reactant materials is provided. In a specific aspect, a reaction system and methods are provided for preparation of boron-containing precursor compounds useful as precursors for ion implantation of boron in substrates. In another specific aspect, a reactor system and methods are provided for manufacture of boron precursors such as B.sub.2F.sub.4.

A one-to-many parallelized millireactor system capable of high throughput production in millireactors. Also disclosed is a method for carrying out multi-phase reactions.

Provided is a method for directed fouling of a substance onto a selected surface. Also provided is an apparatus suitable for directed fouling of a substance onto a selected surface.

Disclosed is a reactor system that contains multiple millireactors, each including a millitube, a first feed line, a second feed line, and a third feed line. Each of the first and second feed lines has a hydraulic damper disposed therein. Also disclosed is a process for conducting in a millitube a triphasic flow reaction that requires a liquid reactant, a gas reactant, and a catalyst.

A photochemical reactor and a photo-oxidation process for manufacturing organic compounds are disclosed. The photo-oxidation generates polyfluorochloro- and/or perfluorocarboxylic acid chloride compounds, in particular halogenated acetyl chlorides, such as polyfluorochloro- and/or perfluoro acetyl chloride. The photo-oxidation process is exothermic. The reactor has a channel or a channels system, including tubes, pipes, or coils, such as coiled tubes or pipes, and, optionally, gasket installations in combination with tubes/pipes, and interior installations, such as microtubes or micropipes. The interior installations avoid formation of hot spots and provide for very good mixing of the reaction medium, such that the photochemical reactions do not only take place in part of reaction medium within a few mm around the UV lighting source. Formation of oxidizing by-products is eliminated, which may otherwise be formed during the photochemical oxidation and possibly accumulate in the photochemical reactor and/or process equipment, such as cooling traps and piping systems.

Methods for converting carbon dioxide (CO.sub.2) into graphene are described. The methods include contacting a metal with gaseous carbon dioxide, and irradiating a surface of the metal with at least one laser beam to convert the gaseous carbon dioxide into graphene on the surface of the metal. Systems for converting carbon dioxide into graphene are also described.
