Improvements in the Manufacture of Artificial Musk.
I, OLIVER IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention to be as follows:-
.!
It has been found that if in the musk-like smelling trinitro derivatives of
hydrocarbons or phenolic ethers, viz.-trinitrobutyltoluene, trinitrobutylxylene, and
trinitrobutylmetacresol ether, for one nitro group be substituted a cyanogen or-al
fatty acid group, such as acetyle and its homologues, the musky odour is not
altered.
11
The dinitro cyanides and dinitro cetones derived from the above named hydro
carbons and phenolic ethers constitute real substitutes for musk.
1..t
My foreign correspondents have now found that also the aldehyde group can
take the place of one nitro group, without changing substantially the properties of"
the compound in respect of odour.
Dinitro-methyl-butyl-benzaldehyde,
dinitro-meta-cresol-ether-aldehyde, otherwise termed dinitro-meta-methyl-methoxyl-
butyl-benzaldehyde, are substances which smeli strongly of musk, and which, as
well as the nitrated hydrocarbons and phenolic ethers hitherto employed, may be
used as substitutes for musk.
dinitro-dimethyl-butyl-benzaldehyde and"
The said aldehydes, methyl-butyl-benzaldehyde,

are prepared from the corresponding hydrocarbons or phenolic ethers by the usual
methods and then nitrated, preferably with strong cold nitric acid.
Example. One part of dimethyl-butyl-benzaldehyde is put into 10 parts of
nitric acid of 99 to 100 per cent. and kept cool; after standing for some time, the
mixture is poured on ice, the precipitate is filtered, washed and crystallised from

page_text: alcohol. The substance thus obtained presents itself in the form of white plates
having a melting point of 112° to 113° C.; it is insoluble in water, soluble in
alcohol, ether and the like. In composition it is dinitro-dimethyl-butyl-benzal-
dehyde.
For the dimethyl-butyl-benzaldehyde in the above example, may be substituted
either of other aldehydes above mentioned.

I, OLIVER IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in

of this invention and in what mauuer the same is to be performed, to be particularly
described and ascertained in and by the following statement:-

Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The herein described manufacture of artificial musk by nitrating dimethyl-
butyl-benzaldehyde, or its homologue methyl-butyl-benzaldehyde, or its substitution:
product methyl-butyl-methoxyl-benzaldehyde.
2. Artificial musk manufactured as above set forth.
