Abstract

103,652. Oman, E. Jan. 20, 1916, [Convention date]. Nitro compounds are prepared by nitrating lignon sulphonic acid or its salts, obtained from waste sulphite-cellulose lye, by adding the concentrated lignon sulphonate solution, or the free acid, to nitric acid or mixed acid while stirring and cooling; the nitro compound precipitates or is separated by adding sulphuric acid or by neutralizing and adding alcohol. The Specification as open to inspection under Sect. 91 (3) (a) is not restricted to carrying out the nitration under the above conditions. This subject-matter does not appear in the Specification as accepted.
