DEFINITION

Classification: 516/66

The compound contains substituted or unsubstituted benzene ring (e.g., di-butyl-naphthalene sulfonic acid):

(under subclass 58) Subject matter in which the organic* compound containing sulfoxy* also contains substituted or unsubstituted benzene ring, such as, di-butyl-naphthalene sulfonic acid. (1) Note. The agent* may be a mixture of sulfonated benzene ring containing compounds. However, if the feedstock for sulfonation was a mineral-oil* (see glossary definition) then the subject matter is located above.
