DEFINITION

Classification: 570/123

Fluorine containing:

(under subclass 101) Compound containing at least one atom of fluorine, and a process for the manufacture or treatment of such compound not classified elsewhere.

(1) Note. This subclass primarily contains patents drawn to the production of saturated fluorine containing compounds by methods not provided for below.
