fer's salts, paranitraniline, dimethyl-
aniline and numerous others.
A glacial acetic acid plant of large
capacity is expected to begin operation
in September and will be of the great
est assistance to the industry in gen.
eral.
Finished Dye Projects
The current monthly production Of
46 manufacturers of finished dyes is at
the rate Of 100000 pounds, or 60,000,-
900 pounds annually, individual outputs
ranging from 500 to over 100000
pounds each. This does not include
any estimate from one plan of the first
magnitude, whose entrance into the in
dustry has just been announced to the
trade, or a score of smaller projects
organized, but not yet in full operation.
The total shown includes only the fig
ures given by the factories of actual
production for the current calendar
year, and makes no allowance for many
plants now in course of construction
which will soon be producing colors on
commercial scale, nor for the output
Of many dyes still in the experimental
stage.
1t is estimated, therefore, that the
present annual domestic output greatly
exceeds in quantity the entire con-
sumption of artificial colors in the
United States during the year 1914,
estimated at 100000 pounds, and is
probably equivalent to the current an
nual consumption, which is consider
ably in excess of that for 1914.
The returns further show that a vast
aV nf @o1n
inventive genius is now being con-
centrated or experimental research to
perfect processes of production, i'm
prove quality and enlarge the variety
of dyes so as to include not only the
more complex known colors currently
used in Europe but possible new ones.
Variety of Colors Obtainable
Coal tar dyes in a variety of colors
suitable for leather, textiles, straw,
paper, inks, stains, pigments, varnishes,
wakes, feathers, furs and for many
other purposes are now regularly OBJ
tainable from domestic sources. Sew
eral manufacturers carry full lines of
direct, acid, basic, chrome, oil and
sulphur colors, while others confine
their efforts to improving and extend
ing their output of particular groups.
Prominent among the colors produced
are nlgrosires, indulines, triphenyl-
methsne dyes, safranines, eosines,
rhodamines, rosanilines,
direct fast. reds, browns and yeIlows
for cotton, fast chrome colors for
wool, Sudan colors, basic violets, syn
thetic indigo and indigotines, alkal
blues for the silk and woollen indus
tries and also for the photographic
trade, metanil yellow, methyl violet,
methylene blue, benzopurpurine, benzo
sky blue, primuine. naphthol green,
rose bengale. gallocyanine and special
chrome and khaki colors.
About dozen firms are giving con-
siderable attention TO developing as
rapidly as the requisite intermediates
are available the triphenyl-methane
dyes, particularly fuchsiGe, methyl vio-
let. methylene blue, magenta, and mala-
chite green. Their OUTPUT of many OF
these coiOrs was not separately stated
by some Of the factories. The itemized
figures given by only few of the
plants, however, show q monthly pre-
duction of this series OF colors amount
ing to $4,000 pounds. OF this quantity
1920 pounds represent methyl violet
and 13,450 pounds methylene blue. Two
specialize on the needed
for these dyes.
There is largely increased produc-
tion and variety of reds. yellows. and
scarlets, prominent among them being
parareds for the printing trade, lithol
red x, psrnlnagenta, coccines, East red
Bordeaux FOR wool. acid rcos and scar
lets, wool scarlet. Bicbrich scarlet,
chrome yellow, metanil yellow, chrome
orange, and brilliant orange A wide
range o Est reds, blues, greens, yell
lowe, blacks. and grays for cotton is
also available.
Colors now produced on commercial
scale that were not made in this coun-
try until recently are alizarin blues,
