An Improvement in the Preparation of Electrolysed Chloride
Solutions for Disinfecting and like Purposes.
We, EUGENE HERMITE, EDWARD JAMES PATERSON, and CHARLES FRIEND
COOPER, all of Pownall Road, Dalston, in the County of London, Electrical
Engineers, do hereby declare the nature of this invention to be as follows:-
In our Specifications No. 15384 of 1887, No. 8177 of 1889 No. 18370 of 1893,
No. 22279 of 1893, and No. 6497 of 1894, we have described the preparation and
application of electrolysed chloride solution for disinfecting, bleaching, and other
purposes.
We have found that in time the electrolysed solution loses strength becoming
less effective, and the object of our present invention is to provide against such
deterioration and also to facilitate the electrolysing of the solution.
For this purpose we add to the chloride solution either before or after, or both
before and after, it is electrolysed a small proportion of alkali, preferably, on
account of cheapness, caustic soda solution or milk of lime. When caustic soda is
employed for this purpose it may be produced by electrolytical decomposition of
common salt, as electric energy is available at the stations where the chloride
solution is electrolysed. Solutions treated with alkali are more effective and
retain their disinfecting and purifying character for considerable periods; they are
available for antiseptic treatment, bleaching and other purposes for which
electrolysed chloride solutions are employed.
Dated this 30th day of January 1896.

In preparing electrolysed chloride solutions for disinfecting and other purposes,
the addition of a small proportion of alkali, as and for the purpose set forth.
