Improvements in Disinfectants and Antiseptics, and in Disinfectant
and Antiseptic Soaps.
I MARK HARGREAVES of Fylde Road, Preston, in the County of Lancaster,
Chemist, do hereby declare the nature of this invention to be as follows:-
My invention consists in forming chlorophenol acids by combining carbolic or
cresylic acids, vegetable tar, or the like (hereinafter referred to as phenols) with
chlorine in suitable proportions, and at suitable temperatures, and forming readily
decomposable chlorophenol salts by combining the said chlorophenol acids with
alkali or alkaline earth.
The said chlorophenol acids may be formed by blowing chlorine gas through the
said phenols or by passing the said phenols down a suitable tower in which a current
of chlorine gas ascends, or by other suitable means chlorine gas is caused to pass
through or amongst the said phenols.
1 directly form the said chlorophenol salts by adding hypochlorites or equivalent
salts of the alkalies or alkaline earths in presence of water to the said phenols, or I
pass chlorine gas through or amongst, or I mix hypochlorites with the said phenols
when combined or mixed with alkali or alkaline earth in the presence of water.
To obtain the said chlorophenol acids or salts for use as disinfectants in the form of
powder mix the said acids or their salts (preferably in solution) with suitable
powdery absorbents such as lime or its carbonate, sand, sawdust or like materials.
Carbonato of lime (preferably after being thoroughly dried by heat) resulting as
a bye produet in the manufacture of caustic soda is suitable for use as an absorbent.
When a disinfectant or antiseptic soap is desired 1 mix the hereinbefore described
chloroplenic acid or its salts with any ordinary soap.

Improvements in Disinfectants and Antiseptics, and in Disinfectant
and Antiseptic Soaps.
I MARK HARGREAVES of 7 Fylde Road Preston in the County of Lancaster,
Chemist 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 :-
First. My invention consists in forming chlorophenol acids and like chloro com-
pounds suitable for use as disinfectants and antiseptics by combining carbolic or
cresylic acids, vegetable tar, or the like (hereinafter referred to as phenols) with
chlorine in suitable proportions, and at suitable temperatures and forming readily
decomposable chlorophenol salts by combining the said chlorophenol acids with alkali
or alkaline earth.
The said chlorophenol acids may be formed by blowing chlorine gas through the
said phenols or by passing the said phenols down a suitable tower in which a current
of chlorine gas ascends, or by other suitable means chlorine gas is caused to pass
through or amongst the said phenols. I combine about three parts by weight of
chlorine with about two parts of phenols. During combination much heat is evolved;
I keep the temperature of the phenols below boiling point and preferably between 100°
ונ...

page_text: and 180° F. by surrounding the vessel in which the operation is performed, with cold
water, or other convenient method of cooling may be employed.
Second. In practice I find it preferable to form directly the said chlorophenol salts
and I do this by adding hypochlorites or equivalent salts of the alkalies or alkaline
earths in presence of water to the said phenols or I pass chlorine gas through or
amongst the said phenols when combined or mixed with alkali or alkaline earth in the
presence of water. Chlorophenol lime salts are readily obtained suitable for purpose
described, by adding solution of bleaching powder to phenols, sufficient bleaching
powder is added to give the relative quantity of free chlorine to the said phenols as
described under first part. A solution of bleaching powder is used sufficiently dilute
and suitable means taken to avoid excessive heating of the solution during the reaction,
chlorophenol soda salts may be obtained by adding sulphate, carbonate or caustic soda
to a solution of chlorophenol lime salts when sulphate, carbonate or hydrate of lime
are precipitated and separated by any convenient method. Or chlorophenol soda
salts may be formed by adding solution of hypochlorite of soda to the said phenols.
Third. To obtain the said chlorophenol acids or salts for use as disinfectants in the
form of powder, I mix the said acids or their salts (preferably in solution) with
suitable powdery absorbant such as lime or its carbonate, sand, sawdust or like
materials. Salt or crude sulphate of soda (salt cake) rendered neutral or alkaline
forms a convenient soluble absorbant. Carbonate of lime (preferably after being
thoroughly dried by heat) resulting as a bye product in the manufacture of caustic
soda is suitable for use as an absorbant.
Fourth. When a disinfectant or antiseptic soap is desired I mix the hereinbefore
described chlorophenic acids or its salts with any ordinary soap. Solution of chloro-
phenol salts are preferably incorporated after saponification of the fat. In dry soap
consisting for the greater part of carbonate of soda with only a small quantity of fat
I preferably add a solution of chlorophenate of soda to a solution of soap and after-
wards mix therewith the desired quantity of carbonate of soda.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
•
First. Treating phenols with chlorine substantially as described under the first part
to obtain products suitable for use as disinfectants and antiseptics.
Second. Chlorophenol salts of the alkalies or alkaline earths obtained substantially
in the manner and for purpose set forth under second part.
Third. Mixing chlorophenol salts of the alkalies or alkaline earths with absorbants
to form disinfecting powder substantially as described under third part.
Fourth. The admixture of chlorophenol acids or salts with soap or equivalent
material for use in washing to form disinfectant and antiseptic soap.
Fifth. Obtaining chlorophenol salts substantially in the manner and for the
purposes set forth under the several heads.
