from Wikipedia, the free encyclopedia

Educt describes a substance separated from raw materials (e.g. vegetable oil from oilseeds ) or, in geology, the original rock in rock metamorphosis .

Furthermore, educt is an outdated expression for a substance (a chemical) with which one wants to carry out a chemical reaction . The term recommended today for this meaning is reactant or starting material .


The term educt from the Latin eductum 'brought out' is explained by the fact that chemists use pure substances that were previously obtained (“brought out”) from natural mixtures or compounds (such as ores ).

In the same context, educt is also used in rock science. This is the name given to the original rocks (educt rocks) before a transformation or change.
