DEFINITION

Classification: 508/135

Distillation residues of crude chemical reaction mixtures, or such residues chemically reacted (e.g., oxo still bottoms, etc.):

(under subclass 110) Compositions which contain residues from distillation of crude chemical reaction mixtures, or the chemical reaction products of such residues.

(1) Note. The reaction of carbon monoxide, olefin, and hydrocarbon is referred to as the "oxo" reaction. Desired products are generally removed from the reaction mixture by a distillation process. The residue remaining in the still pot after distillation, a mixture of diverse compounds, is an example of the materials encompassed by this subclass.
