Katalysoimat

Katalysoimat is a term used in some chemistry texts to denote molecules or species that have undergone catalytic transformation. It encompasses products formed by catalysis, as well as key intermediates and other species that arise within a catalytic cycle. In this sense, a katalysoima is a chemical species whose formation or alteration was facilitated by a catalyst.

The term combines the root "katalyso-" from catalysis with a plural suffix found in some Nordic languages, and is not a universally standardized label in the chemical literature. Its precise scope and definition can vary between subfields or regions.

In practice, katalysoimat are studied by distinguishing them from reactants through kinetics, spectroscopic signatures, and labeling experiments. They may include adsorbed surface intermediates on solid catalysts, transition-state analogs, or products whose isotopic distribution reflects catalytic pathways. In situ spectroscopic techniques, kinetic isotope effects, and reaction-network modeling are commonly used to characterize them.

Typical examples include hydrogenated products of alkenes produced by transition-metal catalysts, hydrolysis or oxidation products formed under catalytic conditions, and intermediates stabilized by the catalytic environment. The properties of katalysoimat—binding strength to the catalyst, residence time, and regio- or chemoselectivity—are determined by the catalyst and reaction conditions rather than by the uncatalyzed reaction.
