COMPLETE SPECIFICATION.
Process for Rendering Amorphous Phosphorus applicable as Sub-
stitute for the Yellow Phosphorus for Matches, Primings, and
the like.
We, MAX BALS, of III Wassergasse 4, Vienna, Chemist, and EUGEN GUROVITS,
of I Bartensteingasse 8, Vienna, Austria, 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 invention relates to a process for rendering amorphous phosphorus
applicable as a substitute for yellow phosphorus for matches and other igniting
materials; it consists essentially in melting sulphur in a heating bath such as of
glycerine, stean, &c., or by the introduction of hot vapours or gases, and then
introducing into the same amorphous phosphorus which is incorporated therewith,
this being effected either with or without the aid of vacuum apparatus, or under
exclusion of the atmosphere or under air or gaseous pressure.
Or the pulverised sulphur or flowers of sulphur is mixed with amorphous
phosphorus and the mixture is then heated in a bath such as above referred to, to
the melting heat of the sulphur or above that point.
The proportions in which the sulphur and amorphous phosphorus are mixed
can be varied; thus to 100 parts by weight of sulphur from 5 to 150 or more
parts of amorphous phosphorus can be mixed. For igniting masses the proportion
of 100 parts of sulphur to from 50 to 150 parts of amorphous phosphorus is
suitable.
The compound thus produced can be pulverised without danger after cooling,
and be worked or applied to any purposes.
The sulphur can either be used pure for the above purpose, or with admixture
of other substances. This intimate combination of amorphous phosphorus with
sulphur by melting, either alone or mixed with other nou explosive substances,
burns very slowly when ignited giving an unextinguishable flame, and is therefore
applicable with advantage for military purposes such as signalling. When mixed
with chloride of potash, glass, and other igniting substances and binding materials
it affords an igniting mass that ignites by friction on any surfaces without noise.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is :-
Process for the application of amorphous phosphorus as a substitute for
yellow phosphorus for igniting substances for matches and the like, consisting in
incorporating amorphous phosphorus with melted sulphur either pure or with
admixture of other substances and either with or without the aid of vacuum, or
under exclusion of air or under air or gaseous pressure, or by mixing powdered
sulphur or flowers of sulphur, either pure or mixed with other substances, with
amorphous phosphorus, and then heating the mixture to the melting point of the
sulphur, or above that point, the compound thus obtained being pulverised after
cooling, and then employed for any purposes, in particular for igniting compounds,
substantially as described.
