Abstract

273,663. Wells, S. D. June 29, 1926, [Convention date]. Pulp, preparation of. - Vegetable fibrous materials such as wood, cereal straws, and grasses are softened for the preparation of pulp by boiling under pressure with a solution of sodium carbonate to which sulphur is added. The process is carried out at temperatures of 120‹ C. and above, and the cooking effect approximates that obtained when sulphide or hydrosulphide is used.
