Abstract
8268. Cross, C. F., and Russell, D. April 14. Waxes. - The waxy compounds contained in esparto grass are recovered from the dust in the debris obtained in cleaning and dusting the grass and also from the alkaline liquor with which the grass is boiled in the preparation of half stuff. The alkaline liquors are kept in tanks, and the wax is removed by skimming, straining, or decanting operations, the separation of the wax being assisted by the injection of air and by cooling the liquor to 50 to 60 C. or the hot liquors are caused to flow in contact with a cooling-surface to which the wax adheres. The skimmings or deposits thus obtained are dried and extracted with volatile solvents. The dust is separated from the general debris, and is treated directly with a solvent, or it may be previously mixed with the skimmings or deposits referred to above. The wax may be in part separated from the dust by applying pressure at a temperature of 100 C. The dust skimmings or deposits may be heated with water under pressure to a temperature of 140 C., whereupon the wax melts and floats out, or the materials may be treated with chemical agents such as nitric acid or other oxidizing - agent or hydrofluoric acid or with a mixture of these acids. In an example, a mixture of sodium chlorate and sulphuric acid is used. After treatment with the oxidizing - agent, the material is boiled in water until free from residues of fibre &c., the free wax rising to the surface.
