chemical process
method or means of somehow changing one or more chemicals or chemical compounds
dissociation
general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into smaller particles such as atoms, ions or radicals, usually in a reversible manner
lead chamber process
industrial process historically used to produce sulfuric acid
flotation
method for the separation of mixtures in process engineering
reduction
gain of electrons in a chemical reaction
lysis
breaking open the membrane of a cell
Saltatory conduction
propagation of action potentials along a nerve cell
one-electron reduction
redox half-reaction in which a chemical species gains a single electron
unit process
one or more grouped operations in a manufacturing system that can be defined and separated from others
Shawinigan process
production process of hydrogen cyanide
leaching
leaching of ores in extractive metallurgy
alkali manufacturing process

osmosis
movement of water towards to more concentrated compartment
cracking
thermal or catalytic decomposition of a compound such as a hydrocarbon into chemical species of smaller molecular weight

process that involves conversion of fat or oil into soap and alcohol by the action of heat in the presence of aqueous alkali
advanced oxidation process
chemical treatment procedures
steam reforming
method for producing hydrogen, carbon monoxide, or other useful products from hydrocarbon fuels
fractional crystallization
geochemical process in which magma evolves in composition because different minerals crystallize and drop away from the melt at different temperatures
Ostwald process
chemical process for producing nitric acid from ammonia and oxygen
calcination
manufacturing process
sorption
physical and chemical process by which one substance becomes attached to another
Ostwald ripening
process in which small crystals preferentially dissolve and re-precipitate onto larger crystals over time
wet oxidation
oxidation process
acetone-butanol-ethanol fermentation
process that uses bacterial fermentation to produce acetone, n-Butanol, and ethanol from carbohydrates such as starch and glucose
dissolution
process of a solute dissolving in a solvent
association
assembling of separate molecular entities into aggregate, especially of oppositely charged free ions into ion pairs or larger and not necessarily well-defined clusters of ions held together by electrostatic attraction;reverse of dissociation
lean-burn
burning of fuel with an excess of air in an internal combustion engine
pan amalgamation
metallurgical process: extraction of silver by amalgamation
electropolishing
removal of oxydable material at the surface of a metal via an electrolytic process
fixing
final step in photographic processing that stabilises the image, removing the unexposed silver halide remaining on the photographic film or photographic paper, leaving behind the reduced metallic silver that forms the image
coalescence
process by which two phases merge to form a larger one with a lower total surface area
hybrid sulfur cycle
water-splitting process
activation
in chemistry and biology, the process whereby something is prepared or excited for a subsequent reaction
