Douglas fir bark fines which contained 74.8 percent
of Klason lignin and 70.2 percent of one percent sodium
hydroxide solubility and decayed Douglas fir wood which
contained 53.9 percent of Klason lignin were subjected to
ethanolysis. A slight modification of the Hibbert's
ethanolysis procedure was used. The monomeric compounds
present...
This investigation was undertaken to develop a procedure
by which the fatty acids could be separated from the
hydroxy fatty acids of bark waxes. The specific hexane-insoluble, benzene-soluble wax used in this research was obtained
from the bark of white fir, Abias concolor, (Lindl.
and Gord.).
The acids were removed...
