A NEW DISINFECTANT AND OXYDIZING AGENT."
Year: 1873

page_text: LETTERS PATENT to William Whitthread, of Liverpool, in the
County of Lancaster, Analytical Chemist, for the Invention of "A
NEW DISINFECTANT AND OXYDIZING AGENT."
PROVISIONAL SPECIFICATION left by the said William Whitthread
at the Office of the Commissioners of Patents, with his Petition, on
the 30th September 1873.
I, WILLIAM WHITTHREAD, of Liverpool, in the County of Lancaster,
Analytical Chemist, do hereby declare the nature of the said Invention
for "A NEW DISINFECTANT AND OXYDIZING AGENT," to be as follows
I add to the matters to be disinfected manganese tetrachloride. The
manganese tetrachloride will be decomposed into two equivalents of
nascent chlorine and one equivalent of magnesic.chloride. Nascent
chlorine obtained in this way is a more powerful disinfecting and
oxydizing agent than ordinary chlorine.
I can also use the higher chlorides, bromides, and iodides of man-
ganese and other metals, instead of tetrachloride.

page_text: When liquid sewage, polluted water, and other deleterious liquids are
treated with any of the above disinfecting agents, I by preference
remove from the treated matters the metallic chloride, bromide, or
iodide they may contain by adding any alkali, alkaline earth, or alkaline
earthy carbonates; or I pass the treated water or other matters through
one or more filters composed of any alkaline carbonate alone or mixed
with sand, gravel, or other suitablo materials or substances.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Whitthread in the Great Seal Patent
Office on the 30th March 1874.

page_text: NOW KNOW YE, that I, the said William Whitthread, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :-
I add to the matters to be disinfected, manganese tetrachloride. The
manganese tetrachloride will be decomposed into two equivalents of
nascent chlorine and one equivalent of magnesic chloride. Nascent
chlorine obtained in this way is a more powerful disinfecting and
oxydizing agent than ordinary chlorine.
I can also use the higher chlorides, bromides, and iodides of man-
ganese and other metals, instead of tetrachloride.
When liquid sewage, polluted water, and other deleterious liquids are
treated with any of the above disinfecting agents, I by preference remove
from the treated matters, the metallic chloride, bromide, or iodide they
may contain by adding any alkali, alkaline earth, or alkaline earthy
carbonate; or I pass the treated water or other matters through one or
more filters composed of any alkaline carbonate, or alkaline earthy
carbonate alone or mixed with sand, gravel, or other suitable materials
or substances.
Having thus described the nature of my said Invention, I claim the
application as a disinfectant and oxydizing agent of manganese tetra-
chloride, the higher chlorides, bromides, and iodides of manganese and
other metals.
In witness whereof, I, the said William Whitthread, have here-
unto set my hand and seal, this Thirtieth day of March, in the
year of our Lord One thousand eight hundred and seventy-
