PROVISIONAL SPECIFICATION.
A New or Improved Sweetening Substance, and a Process for its
Manufacture.
.I, EDGAR RODRIQUEZ SAVIGNY, Journalist 145 Fleet Street, London, E.C. do hereby
declare the nature of this invention to be as follows:
My invention relates to a new or improved sweetening substance and to a process
for its manufacture. This new substance is at least five hundred times sweeter than
sugar and is cheaper to make than the much less intense sweetner known commercially
as "saccharin." In order to inake the new substance mentioned in the title of this
application proceed in or in about the following manner, that is to say. I place
Toluoleyansulfamid in hot distilled water. This is then saponified by adding a sufficient
quantity of dry potash. After this the mixture is boiled for several hours and then
allowed to cool. Sulphuric acid is then added in quantity sufficient to cause the
Benzoesulfinid (which is my new sweetening substance) to separate itself as a sediment
in the form of a white crystalline powder. This powder I mix with distilled water and
the Benzoe-sulfinid can be crystallized out as transparent crystals. In order to
purify these crystals and to separate therefrom any undesirable admixtures I add to
them a sufficiency of Dimethylbenzol (C.H.(CH3)2) and let the whole rest in a
lixiviating tank till the residuum ceases to have a sweet taste. On cooling, the pure
Benzoe-sulfinid (which I call "Sugarine ") will separate itself in the form of white
crystals.

A New or Improved Sweetening Substance, and a Process for its
Manufacture.
I, EDGAR RODRIQUEZ SAVIGNY, Journalist, 145, Fleet Street, London, E.C., do
hereby declare the nature of this invention and in what manner the saine is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to a new or improved sweetening substance and to a process
for its manufacture. This new substance is at least five hundred times sweeter than
sugar and is cheaper to make than the much less intense sweetner commonly known as
"Saccharin." In order to make this new sweetening material, I proceed in or in about
the following manner. Toluolcyansulfamid is placed in hot distilled water. Sufficient
dry potash is added to the above mixture to saponify it, and after boiling the whole
for some hours, it is allowed to cool. Sulphuric acid is then added in quantity
sufficient to cause methyl-benzolsulfinid (which is my new sweetening substance) to

page_text: separate, as a sediment in the form of a white crystalline powder. The powder is then
mixed with distilled water and the methyl-benzolsulfinid can be crystallised out as
transparent crystals. To purify these crystals, and to separate therefrom any
undesirable admixture, I add to thein a sufficiency of dimethylbenzol (C,H,CH,)²
and let the whole rest in a lixiviating tank till the residuum ceases to have a sweet
taste. On cooling, the pure methylbenzolsulfinid (which I call Sugarine") will
separate in the form of white crystals.

As an example of the quantities of materials to be employed, but without restricting
myself to those precise proportions, I may say that in practically carrying out the
process, one part of toluolcyansulfinid may be dissolved in six parts of distilled water
at a temperature of 85 C., and after saponifying by dry potash, the mixture may be
boiled nine or ten hours. After cooling, sulphuric acid is added and the resulting
sediment (methyl-benzolsulfinid) mixed with distilled water as already mentioned, the
powder which then crystallises out being purified with dimethylbenzol at the rate of
say nine parts of the dimethylbenzol to one part of the crystals to be purified, the
after proceedings being as above mentioned.
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 :-
CLAIMS.
:-
1. The new sweetening substance méthyl-benzolsulfinid substantially as described
in the above specification.
2. The process, substantially as described in the above specification, for producing
methyl-benzolsulfinid, the said process consisting essentially in saponifying toluol-
cyansulfamid and adding thereto sulphuric acid to precipitate the methyl-
benzolsulfinid which is finally obtained in a pure form by adding diamethylbenzol,
the whole substantially as described in the above specification.
