Abstract

528,268. Treating lignin. SHERRARD, E. C., and HARRIS, E. E. May 2, 1939, No. 13085. Convention date, May, 10, 1938. [Class 95] [Also in Group IV] Lignin is hydrogenated under heat and pressure in the presence of a hydrogenation catalyst to give a graduated series of products which when using copper chromium oxide as a catalyst were separated by fractional distillation. The fraction boiling above 150‹C. at 1 mm. solidifies into a hard vitreous mass. When nickel is used as the catalyst, a similar product is obtained except that it flows more readily and forms a quick flowing thermoplastic composition. If desired the lignin may be prepurified by removing sugars, inorganic materials and impurities. Two examples are given using copper chromium oxide and Raney nickel catalysts.
