PROVISIONAL SPECIFICATION.
An Improved Manufacture of Compounds of Iron with Fatty Acids.
I, ALFRED KIRBY HUNTINGTON, of King's College, Strand, in the County of
London, Professor of Metallurgy, do hereby declare the nature of this invention
to be as follows:-
I
My invention relates to the manufacture of compounds of iron with fatty acids
which I effect in the following manner. In compounding iron with oleic acid, I
dissolve the oleic acid along with soda or potash in alcohol diluted with water.
also separately dissolve in alcohol and water sulphate of peroxide of iron. I mix
the two solutions and thereby obtain liquid olëate of iron containing alcohol, which
by gravity becomes separated from the rest of the liquid and can be removed by
decantation or siphoning. In like manner linoleic acid may be compounded with
iron. Instead of employing the oleic or linoleic acid along with alkali, saponified
oils containing these acids may be used, but the products in this case may contain
other constituents of the oils. The clear olëate or linoleate produced is thoroughly
washed with alcohol and the alcohol retained by the separated olëate or linoleate is
distilled off. During and for sometime after the final removal of the alcohol by
distillation, a sediment is precipitated which may be removed by filtration or
decantation. If the oleate or linoleate is to be used in conjunction with an oil, a
small portion of the oil may be added to the oleate preferably before the alcohol
has been all distilled off; this causes the insoluble portion to precipitate in a short
time.

COMPLETE SPECIFICATION.
An Improved Manufacture of Compounds of Iron with Fatty Acids.
I, ALFRED KIRBY HUNTINGTON, of King's College, Strand, in the County of
London, Professor of Metallurgy, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention relates to the manufacture of compounds of iron with fatty acids,
which I effect in the following manner. In compounding iron with oleic acid, I
dissolve about 7 parts by weight of the oleic acid along with about 1 part of soda
or its equivalent in potash in about 80 parts of alcohol diluted with about 20 parts
of water. I also separately dissolve in about 56 parts of alcohol and 28 parts of
water 4 parts of sulphate of peroxide of iron. I mix the two solutions, whereupon
a reaction takes place producing liquid olëate of iron containing alcohol and an
alcoholic solution of sulphate of soda. The olëate containing alcohol becomes
separated by gravity from the rest of the liquid and can be removed by decantation
or siphoning. In like manner, linoleic acid may be compounded with iron. Instead
of employing the olëic or linoleic acid along with alkali, saponified oils containing
these acids may be used, but the products in this case may contain other constituents
of the oils. The clear oleate or linoleate produced is thoroughly washed with
alcohol diluted with about 3d of its volume of water and the alcohol retained by
the separated oleate or linoleate is distilled off. During and for sometime after the

page_text: final removal of the alcohol by distillation, a sediment is precipitated which may be
removed by filtration or decantation. If the olëate or linoleate is to be used in
conjunction with an oil, a small portion of the oil may be added to the oleate
preferably before the alcohol has been all distilled off; this causes the insoluble
portion to precipitate in a short time.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The manufacture of compounds of iron with fatty acids, substantially as herein
described.
