"IMPROVEMENTS IN THE MANUFACTURE OF A SUBSTITUTE FOR BISULPHIDE OF
CARBON
"
Our invention relates to the production from petroleum of a substitute for
bisulphide of carbon and which can be used for extracting oils and anthracine for
dissolving gums, resins and analogous substances for waterproofing and for
vulcanizing india, rubber in conjunction with chloride of sulphur or other
vulcanizing agents.
"
To obtain our improved substitute which we call "Vulcoleine
distillate or fraction from petroleum which passes over between the temperatures of
we take that
one hundred degrees Fahrenheit and two hundred and twelve degrees Fahrenheit
or thereabout, (or we take the fraction known as spirit or naphtha) and treat the
same as follows:-
To every one hundred gallons we add from two to three gallons of oil of vitriol
or sulphuric acid with constant agitation, continued as long as may be necessary in
a suitable vessel, it is then allowed to subside and the liquor decanted from the
sediment is run into a still with from one to two per cent of its weight of lime or
other dehydrating medium, calcium carbonate or other alkaline carbonates or oxides
or metals capable of removing or destroying any sulpho-oils which may have been

without injecting steam or water into the contents of the still.
Before distilling we sometimes submit the liquid to repeated treatment with
fresh sulphuric acid as above mentioned until the acid ceases to be colored, or
nearly so.
As the distillate comes over, the receivers are exchanged as soon as the product
which is coming over reaches a specific gravity from about 680 to 690, water being
taken as 1000.
By our improvements we remove the portions of petroleum unsuited for a
substitute for bisulphide of carbon and effect thereby considerable economy both
in material and bulks of liquid to be operated on
