PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Disinfectants and Antiseptio
Compounds.
CHARLES COLWILL WHITAKER Chemical Manufacturer 8 Tyrrell Road East
Dulwich London, S.E. do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements in the use of tar bases, such as
pyridine, picoline quinoline in admixture with phenol & cresols & their soda
compounds in such proportions as to produce a powerfull disinfectant & insecticide
which will call "Deodo," soluble in water, to be employed in the liquid or solid
form as required.

Improvements in the Manufacture of Disinfectants and Antiseptic
Compounds.
CHARLES COLWILL WHITAKER 8 Tyrrell Road East Dulwich Chemical
Manufacturer, 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 :-
This invention relates to certain improvements in the use of tar bases, such as
pyridine, picoline, quinoline, and the like, and their respective salts, such as
chlorides, sulphates etc., either together or separately, in admixture with phenols,
cresols, and their respective combinations with alkalies, such as soda, potash etc.,
in such proportions as to form a compound that is freely soluble in water in all
proportions, and in which mixture a certain proportion of beta naphthol is
dissolved, thereby producing a most powerful disinfectant, insecticide and sheep
dip to be employed as a liquid or solid as required.
The compound I produce by my invention comprising both the liquid and the
solid form I purpose calling "Deodo."
In making my liquid compound, I first prepare a solution, by mixing 25 gallons
of pyridine bases and allied bases, such as picoline quinoline and the like, with
100 gallons of water in any suitable vessel, preferably one supplied with an
agitator, or I dissolve 100 lbs. (pounds) of the salt or salts of pyridine bases,
picoline, quinoline and the like in 100 gallons of water. I then prepare the
alkaline carbolate or cresylate by dissolving 30 gallons of crude carbolic acid or
cresylic acid in 100 gallons of caustic soda or caustic potash having a specific
gravity of 24° Twaddle hydrometer @ 60° F.
I then mix two parts of the solution of pyridine bases with one part of the
solution of carbolate or cresylate of soda or potash, or I two parts of the solution
of pyridine salts as herein described with one part of the solution of the alkaline
carbolate or cresylate, or I mix one part of the solution of pyridine salts with one

page_text: part of the alkaline carbolate or cresylate according to the grade of disinfectant
and sheep dip I wish to produce.
The mixed solutions of the foregoing is then agitated with carbolic acid or
cresylic acid in excess so that the liquid is saturated with carbolic or cresylic acid
and the undissolved portion of the acids is drawn off. To the clear solution thus
obtained I then add from one half to one per cent. of beta-naphthol.
Iu preparing my solid compound I incorporate with suitable mixing plant
varying proportions 5% 10%-15%-20% of my mixed solution prepared as
described in the foregoing with powdered chalk, gypsum and the like.
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 1
claim is.
1st. A liquid preparation by combining certain powerful disinfectant compounds
as herein set forth in such manner as to produce powerful soluble disinfectants,
insectcides, & sheep dip.
2nd. A solid preparation by incorporating the liquid compound with a suitable
absorbant so that the whole can be applied as a powder.
Dated this 22nd day of August 1896.
