TRUVIDIONAL SPECIFICATION.
A Process for the Production of Artificial Musk.
I, ALBERT BAUR of Mulhouse, Alsace, Doctor do hereby declare the nature of
this invention to be as follows:-
In the Specifications No. 18521 of 1888, No. 4693 of 1889 and No. 15687
of 1890 processes for the production of artificial musk are described by nitration
of aromatic hydrocarbons which are homologues of benzene and also contain
methylic, ethylic, butylic, propylic or amylic side groups.
I have found that not only these simple aromatic hydrocarbons containing such
groups but that also complicated aromatic hydrocarbons which contain these side
groups give musk by nitration. They are, by this operation, split up into the lower
nitro derivatives referred to in the above mentioned Specifications. For instance
dibutylditolylmethane and tributyltritolylmethane give trinitrobutyltoluene.
According to my invention, I introduce one part of dibutyltolylmethane or tributyl-
tritolylmethane or dibutyldixilylmethane or tributyltrixilylmethane into 15 parts
of a mixture containing one part of fuming nitric acid and two parts of sulphuric
acid, containing about 10 per cent. SO3, and I heat the mixture for several hours on
the water-bath. By then pouring the liquid into water, a crystalline mass, which
smells strongly of musk, is obtained. In the ease of the butyltolyl derivatives, it
is trinitrobutyltoluene, in the case of the butylxilyl derivatives, it is trinitro-
butylxylene.

COMPLETE SPECIFICATION.
A Process for the Production of Artificial Musk.
I, ALBERT BAUR, of Mulhouse, Alsace, Doctor, 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:-
In the Specifications No. 18521 of 1888, No. 4693 of 1889 and No. 15687
of 1890 are described processes for the production of artificial musk by nitration
of aromatic hydrocarbons which are homologues of benzene and also contain
methylic, ethylic, butylic, propylic or amylic side groups.
I have found that, not only these simple aromatic hydrocarbons containing such
groups, but that also complicated aromatic hydrocarbons which contain these side
groups give musk by uitration. They are, by this operation, split up into the
lower nitro derivatives as described in the Specifications above referred to.
For instance dibutylditolylmethane and tributyltritolylmethane give trinitro-
butyltoluene.
According to my invention introduce one part of dibutylditolylmethane or
tributyltritolylmethane or dibutyldixilylmethane or tributyltrixilylmethane into
15 parts of a mixture containing one part of fuming nitric acid and two parts of
sulphuric acid, containing about 10 per cent. SO, and I heat the mixture for

butyltolyl derivatives, it is trinitrobutyltoluene, in the ease of the butylxilyl
derivatives, it is trinitrobutylxylene.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what
I claim is :-
The production of artificial musk by treatment as herein described of complicated
aromatic hydrocarbons containing the methyl or ethyl and the butyl or propyl and
amyl groups, such for instance as di- or tri-butyl di- or tri-tolylmethane or di- or
tri-butyl di- or tri-xilylmethane.
