C25B ELECTROLYTIC OR ELECTROPHORETIC PROCESSES FOR THE PRODUCTION OF COMPOUNDS OR NON- METALS; APPARATUS THEREFOR
Introduced: July 1974
Classification Context
- Section:
- CHEMISTRY; METALLURGY
- Class:
- ELECTROLYTIC OR ELECTROPHORETIC PROCESSES; APPARATUS THEREFOR
- Subclass:
- ELECTROLYTIC OR ELECTROPHORETIC PROCESSES FOR THE PRODUCTION OF COMPOUNDS OR NON- METALS; APPARATUS THEREFOR
Description
C25B covers electrolytic and electrophoretic processes for synthesizing inorganic and organic compounds, as well as non-metallic substances, along with the specialized equipment used in these operations. This includes electrochemical production of chemicals such as halogens, hydrogen, oxygen, acids, bases, salts, and various industrial compounds through direct electrochemical conversion. The classification also encompasses electrophoretic deposition and separation techniques for preparing non-metallic materials. Related electrorefining and electrowinning of metals are excluded and fall under C25C instead.
Scope Notes
Limiting references: Treatment of water, waste water or sewage by electrochemical means, e.g. electrolysis electrodes therefor Separation or purification of peptides, e.g. of proteins, by electrophoresis Inhibiting corrosion of metals by anodic or cathodic protection Single crystal growth
