A Process for the Production of a Substance to be called Chloral-
formamide or Chloralamide
J, JOSEPH FRIEDRICH VON MERING residing at Strassburg in the Empire of
Germany Doctor of Medicine do hereby declare the nature of the said invention to
be as follows.
The present invention has reference to the production of a new combination, to be
called Chloralformamide (C, H Cl, O CHO. ÑH₂) which for the sake of brevity is
hereinafter called "Chloralamide
دو
The chloral or chloral hydrate, which has attained such a high place in consideration
of its medicinal and non-putrefactive qualities, is however comparatively easily
decomposed and consequently only possesses small capability for lasting and only
preserves, for instance, animal bodies for a comparatively short time. 0
In consequence of experiments which have been made in order to produce a
combination, which should have the useful qualities of the chloral or chloral hydrate
with greater fixity and lasting qualities, the above mentioned chloralformamide has
been produced.
According to this present invention the said chloralformamide is obtained by the
action of chloral (C₂ H Cl, O) on Formamide (CHO NH,) in the ratio of their
molecular weights. The mixture becomes warmed and gradually thickens until it
becomes a solid crystalline mass consisting of the new combination namely chloral-
formamide (C, H ČI, O CHO NH₂)
If this mass be dissolved in water or another of the hereinafter mentioned solvents
of the chloralformamide, and if the latter be allowed to crystallize, a combination will
result which is colourless and without smell in the form of crystals. These crystals
melt at 115° 116° C., and are soluble in water, and easily soluble in alcohol, ether,
acetic ether, glycerine and acetone. This new combination is soluble in water without
undergoing any alteration as is the case with chloral bydrate. The chloral formamide
is a hypnoticum" or soporific like chloral hydrate, but has no corroding action, is
without smell and has a mild and slightly bitter taste, does not affect the action of
the heart, nor does it disturb the digestion Like chloral it is capable of disinfecting
and preventing putrefaction but unlike the chloral has more lasting qualities.

A Process for the Production of a Substance to be called Chloral-
formamide or Chloralamide
I, JOSEPH FRIEDRICH VON MERING, residing at Strassburg, in the Empire of
Germany, Doctor of Medicine, 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 present invention has reference to the production of a new combination to be
called Chloralformamide (C, H CI, O CHO NH,) which for the sake of brevity is
hereafter called Chloralamide.
The chloral or chloral hydrate which has attained such a high place in consideration
of its medicinal and non-putrefactive qualities, is however comparatively easily
decomposed and consequently only possesses small capability for lasting and only
preserves for instance, animal bodies, for a comparatively short time.

page_text: In consequence of experiments which have been made in order to produce a
combination, which should have the useful qualities of the chloral or chloral-hydrate
with greater fixity and lasting qualities, the above mentioned chloral-formamide has
been produced.
According to this present invention the said chloral formamide is obtained by the
action of chloral (C; H Cl, O) on Formamide (CHO NH,) in the ratio of their
molecular weights. The mixture becomes warmed and gradually thickens until it
becomes a solid crystalline mass consisting of the new combination namely Chloral-
formamide (C, H ČI, O CHO. NH₂).
If this mass be dissolved in water or another of the hereinafter mentioned solvents
of the chloral-formamide and if the latter be allowed to crystallize a combination will
result which is colourless and without smell in the form of crystals. These crystals
melt at about 115°-116° C. and are soluble in water and easily soluble in alcohol,
ether, acetic ether, glycerine and acetone This new combination is soluble in water
without undergoing any alteration as is the case with chloral hydrate. The chloral
formamide is a "hypnoticum or soporific like chloral-hydrate, but has no corroding
action, is without smell and has a mild and slightly bitter taste, does not affect the
action of the heart nor does it disturb the digestion. Like chloral it is capable of
disinfecting and preventing putrefaction but unlike the chloral has more lasting
qualities.
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. The production of chloral-formamide (chloralamide) by the application of
chloral and formamide.
Second. As a new product chloral-formamide called chloralamide which in a pure
condition forms a colourless, odourless, crystalline mass essentially of the formula
C, H CI, O CHO NH,, which mass melts at about 115° C. and is soluble in water,
alcohol, ether, acetic ether, glycerine and acetone.
