PROVISIONAL SPECIFICATION.
A Method for Producing a Substitute for Musk.
I ALBERT BAUR of Gispersleben in the Empire of Germany, Doctor do hereby
declare the nature of this invention to be as follows:-
:-
The object of this invention is to produce a compound or material or series of
compounds or materials having the properties of musk.
To this end I purpose to make a nitrated hydrocarbon of the C₁₁ H₁ group and
proceed as follows.
Toluole is mixed with a haloid combination of butane and boiled with addition of
chloride or bromide of aluminium. Water is added to the product and it is then
distilled with steam, and that portion which distills over at a temperature between 1.70°
and, 200° Centigrade is taken and treated with fuming nitric acid and fuming sulphuric
acid. The resulting product is washed with water and crystallized from alcohol.
The product may be disolved in alcohol and on addition of a small quantity of
ammonia or salamoniac will exhibit all the essential properties of a tincture of musk.

COMPLETE SPECIFICATION.
A Method for Producing a Substitute for Musk.
I, ALBERT BAUR of Gispersleben in the Empire of Germany, Doctor, do hereby
declare the nature of my invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
The object of this invention is to produce a compound or material, or series of
compounds or materials, having the properties of musk.
To this end I make a nitrated hydro-carbon of the C H₁e group and proceed as
follows:
Toluole is mixed with a haloid combination of butane and boiled with addition of
chloride or, bromide of aluminium. Water is added to the product and it is then
distilled with steam and that portion which distills over at a temperature between
170° and 200° Centigrade is taken and treated with fuming nitric acid and fuming
sulphuric acid. The resulting product is washed with water and crystallized from
alcohol.
The product may be dissolved in alcohol and on addition of a small quantity of
ammonia or sal-ammoniac, will exhibit all the essential properties of a tincture
of musk.
For carrying the invention into practice 5 parts of toluole are mixed with one part
of butylie bromide or butylie chloride or butylie iodide and to these may be added
gradually whilst boiling part of aluminium chloride or aluminium bromide this
results in the development of hydro bromic acid or hydro-chloric acid or hydriodic
acid respectively and a product of reaction is obtained from which by the action of
steam the hydrocarbon C₁ H₁s and unchanged toluole are distilled. By the admission
of steam the hydrocarbon is carried along and may be obtained in a condenser as a
colourless oil floating on the water. The oil removed and dried by means of chloride
of calcium is fractioned and in this manner the necessary hydrocarbon for the
production of artificial musk is obtained, 100 parts of the former giving a like
quantity of musk preparation. 3 parts of fuming nitric acid of 152 specific weight
and 6 parts of fuming sulphuric acid are mixed together and to this mixture is
carefully added whilst cooling one part of the hydrocarbon aforesaid.

is heated up to a temperature of about 100° C. After cooling the nitro-product is
precipitated by pouring into cold water of about 5 to 6 times the volume and is
separated from superfluous acid by washing with cold water. The nitro product
separates first as a heavy viscid oil, which after some time hardens into a firm
crystalline substance.
The raw nitro product is then purified by re-crystallization from alcohol of 90%
strength. The purified product crystallizes out in yellowish-white-needles, possessing
a strong smell of musk.
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
