Century Dictionary and Cyclopedia

1. n. The act of making, or the state of being made, dense or compact; reduction of volume or compass, as by pressure, concentration, or elimination of foreign material; closer union of parts; compression; consolidation: used in both literal and figurative senses.
2. n. In chem. and physical, the act of reducing a gas or vapor to a liquid or solid form.
3. n. In organic chemistry, the union of two carbon atoms which may be in the same or in different molecules. Thus acetylene, C₂H₂, condenses to benzene, C₆H₆. In recent years the term has been applied to reactions involving the union of a carbon atom to an atom of some other polyvalent element, usually accompanied by the removal of the elements of water. Thus acetaldehyde, C₂H₄O, and hydroxylamine, NH₂OH, condense to form acetaldoxime, C₂H₄NOH, and water, H₂O.
