Class Information
Number: 204/164
Name: Chemistry: electrical and wave energy > Processes and products > Electrostatic field or electrical discharge
Description: Chemical processes which have for their purpose the preparation of compounds or elements through chemical reactions brought about by the agency of electrical energy within an electrostatic field or a field within which electrical discharging takes place. For example, the conversion of the surface of a polymeric material to produce a film thereon. This group includes both the synthetic production of compounds or elements and, likewise the chemical modification or chemical purification of compounds or elements, making use of electrical energy to effect the chemical changes in such processes. The processes falling within this group of subclasses are those whose purpose is for the production of compounds or elements by chemical reaction, but not those wherein a material or composition is treated, such as a metal, tobacco, foods, beverages, leather and the like, and in which a chemical change may be brought about. This group of subclasses likewise includes processes wherein one or both of the reactants are subjected to an electrostatic field or electrical discharge for the purpose of activation and the desired reaction is effected by mere mixing while such reactant or reactants are in the activated condition. This usually consists of a step of ionization followed immediately by mixture with another ionized or unionized substance, the reaction following as a matter of course due to the condition of the mixed reactants.
