Abstract
103,654. Oman, E. Jan. 20, 1916, [Convention date]. Nitroso compounds are prepared by treating with nitrous anhydride, or substances yielding it, lignon sulphonic acid or its salts, obtained from waste sulphite-cellulose lye. The process may be effected by treating the lye, deprived of lignine sulphonates and concentrated, with a nitrite and acid, or with gaseous nitrous anliydride; the product is salted out from the reaction mass. The Specification as open to inspection under Sect. 91 (3) (a) states also that waste sulphitecellulose lye itself may be treated by the process. This subject-matter does not appear in the Specification as accepted.
