NEW CHEMICAL PROCESSES - PREPARATION or
SOLUBLE SPICES, ETc.-Among the most curious OF
the modern discoveries in chemistry the methods Of
producing from highly noxious and offensive materials
compounds which possess the properties of the most
agreeable favors and essences, and which in
tua substitutes for the preparations before made
from fruits and flowers. At the present time Of
tie choicest for culinary purposes pro-
duced from the fed fusel oil which separated from
the crude brandes and WHISTLES in the process Of rect
fcation and the most delicious perfumes for the toilet
from substances extracted from the coal tar of the gas
works and even from still more offensive substances.
A peculiar disgusting compound of sulphur and car
bon, obtained a liquid by condensng the yapor Of
sulphur after passing il red hot charcoal, and
known sulpburet Of carbon has long been known AZ
powerful solvent Of India rubber, for which purpose
il has of late years been manufactured in large quaint
ties is distinguished for its pungent taste and Pc
culiar feted odor due to the sulphureted hydrogen
which adheres to il. This compound has recently
come into in France, under patent of NJ. Boniere
of Rouen for making what he desgnates soluble spices,
and other soluble preparations of food. BY Of
it he dssoves the active principles of the spices,
and also of other strongly favored articles used
condiments, such garlic onions shallot and various
fruits and causing these to be taken up by some inert
substance adapted the particular extract he prepares
them for the of the table putting them up in
GELS intended to be placed upon consoles etageres
and made attractive by the displayed in their
namcniaon.
In bis process the first object is to purify and deodo
rize the suphuret of carbon. This is done peculiar
dsng apparatus, the liquid as it enters the first still
falling upon concentrated solution of causc potash
of soft suphate of lead heated to 1902 40 Fab
renhet. The vapor then passes successfully in other
stills, each of which contains solutions of
pounds with alkaline metallic base, as of potash
salts of lead iron, copper, &c., of barytes. 1t then
condenses in the of the STILL and is collected
der distilled water in small glass vessel. The sui
phuret also be recied by simply bringing it in
tact with concentrated solutions of the chemical re-
gents named and decanting successfully from these
many times. When rectied the disagreeablc smell of
suphueted hydrogen has entirely disappeared and an
ETHEREAL product is obtained somewhat resembling chic
reform in its odor and possessing solvent properties fax
superior the impure commercial article and leaving
trace after evaporation. 1t is then ready for the
preparation of soluble spices which, in the Of
pepper for example, is conducted follows: The
spice being ground to powder is put in iron wire cages
with sheet-iron bottoms. These cages being set in
cylindrical vessel which they fitted, the purified
suphuret of carbon admitted through the bottom Of
the outer cylinder and flowing up through the cages
dssoves ont the active principle of the spice and bys
side pipe of glass placed nearthe top the liquid charged
with this principle is let off into a eauldron still. In
this is placed substance, common SALT or salt
peter sugar of milk other sugar other mat
ter as dextrine gum, -four, for absorbing and be-
coming saturated with the extract The lower portion
Of this still is double and steam at the temperature Of
liOo TO lijo Fahrenheit being introduced in the space
at the bottom the sulphuret of carbon entirely vol
atzed and passing through the worm of condenser is
recovered, to be used again in successive opera
ons, while the extracts is held by the absorbing sub
stance placed in the still The length of time required
for continuing the process in order to extract all the
active principle is indicated by the color of the liquid
which flows through the glass tube leading from tho
cylinder to the still. The connection between the two
is then closed and the liquor remaining in the Under
is allowed to flow out through tho bottom; after which
steam is admitted to carry oil the last portions of suL
phuIet of carbon which is collected and condensed IN
another vessel BY thsprocess the active principhd
