DEFINITION

Classification: 510/408

Azeotropic or azeotrope-like composition:

(under subclass 407) Compositions which are substantially constant boiling, and which approximate or duplicate the behavior of a single-substance solvent at a given temperature.

(1) Note. The distillates of azeotropes have the same composition as the original mixture.
