No. 30639.—20th December, 1910.—FRED BEDFORD,
Ph.D., B.Sc., London, Chemist, and CHARLES EDWARD
WILLIAMS, Seed-crusher, both of Sleaford, in the County of
Lincoln, England. Improvements in or relating to a process
for the conversion of unsaturated fatty acids, their glycerides
and other esters, into the corresponding saturated compounds.
Extracts from Specification.—It has hitherto been proposed
to effect the conversion of unsaturated compounds as set out
above into the corresponding saturated compounds by treatment with hydrogen in the presence of a catalyser, the latter
being always applied in the form of metal in a finely divided
state. . . . In carrying our invention into effect we
employ the catalyser in the form of an oxide, nickel-oxide
being found to be the most rapid of all the catalytic oxides
in its action, only ½ to 1 per cent. of nickel-oxide being, in
general, required to be added to the oil, the latter being placed
in any convenient tank or vessel through which hydrogen
may be forced from a spray or ring-pipe and being heated
by superheated steam passing through a coil in the tank or
by means of a fire, oil-bath, or other suitable means.
