PROVISIONAL SPECIFICATION.
Improvements in or connected with the Manufacture of
Disinfectants.
I, RICHARD ENGLAND, of 36, Mark Lane, in the City of London, Chemical
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the combination with disinfectants such for example as
carbolic and tar acids, of fertilizing agents such as the phosphates of alumina and
iron, lime and the like whereby I obtain a combined disinfectant and fertilizer.
In carrying out my invention I add to the disinfecting agent such a proportion
of a fertilizing agent as will serve as a vehicle or base for the conveyance of the
disinfectant, any suitable absorbent such as gypsum being added.
By my invention I thus produce a compound which is adapted first for use as a.
disinfectant and subsequently as a fertilizer.

Improvements in or connected with the Manufacture of
Disinfectants.
I, RICHARD ENGLAND, of 36, Mark Lane, in the City of London, 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 the combination with disinfectants, such for example
as carbolic or other tar acids, of fertilizing agents such as the phosphates of
alumina and iron, phosphate of lime, and the like whereby I obtain a combined
disinfectant and fertilizer.
In carrying out my invention I add to the disinfecting agent such a proportion
of a fertilizing material or agent as will serve as a vehicle or base for the
conveyance of the disinfectant, any suitable absorbent or diluent such as gypsum
being added when required.
The proportions of disinfecting and fertilizing agents will obviously vary
according to the nature of the disinfectant or the fertilizing material or agent and
the percentage of phosphoric acid or nitrogen to be contained in the combined
disinfectant and fertilizer. I have, however, found that the following proportions
(which I give by way of example) will give good results in practice.
Where phosphate of lime is used as the fertilizing agent or base for the
conveyance of the disinfectant to about 60 parts by weight of the phosphate I add
about 6 parts by weight of tar acids and about 30 parts by weight of a suitable
diluent such as calcined gypsum.
In cases where a disinfecting agent such as ferric sulphate is used in combination
with tar acids a smaller proportion of the diluent is used.

page_text: Where phosphate of alumina in a calcined form is used then about 30 parts of
the phosphate of alumina give good results; or where the phosphates of lime and
alumina are both used as the base or conveyor I employ about 20 parts of phosphate
of lime and about 20 parts of the phosphate of alumina, the quantities of disinfecting
material being similar to those above stated and the diluent varied according to
the percentage of phosphoric acid or nitrogen required.
By my invention I thus produce a compound which is adapted first for use as a
disinfectant and subsequently as a fertilizer.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that
what I claim is :-
The described improvements in or connected with the manufacture of disinfectants,
such improvements consisting in adding to the disinfecting agent a fertilizing
material or agent to serve as a vehicle or base for the conveyance of the disinfectant,
a suitable diluent being added if required substantially as, and for the purposes,
herein before described.
