igoy~\ Wheeler — The Condensation of Chloral 103 
The para compound crystallizes from ligroin in brilliant 
scales, showing a strong pink color in the mass. It melts at 
118°-120° and decomposes at 158°. It is fairly soluble in 
cold benzene, alcohol and ether. It is readily soluble in gla- 
cial acetic acid, hot benzene and hot alcohol. The hot alco- 
hol solution emits a most disagreeable odor and on spontane- 
ous evaporation to dryness a jet black crystalline mass 
remains. It is very slightly soluble in cold ligroin and not 
readily in hot ligroin. On treatment with bromine in glacial 
acetic acid solution a crystalline product is obtained which 
blackens at about 198°. This compound will be studied 
further. 
Chloral and Anthranilic Acid. 
The product obtained in this case depends upon the pro- 
portions used. One molecule of chloral will condense with 
one or two molecules of anthranilic acid with the elimination 
of one molecule of water. The two products have been de- 
scribed by Niementowski but his method yields a mixture 
and we have improved upon it since we wish to make the 
compounds in quantity in order to study their bromo deriva- 
tives.

With W. S. Dickson. Five grams of anthranilic acid were 
dissolved in 40cc boiling benzene (a saturated solution) and 
5.5 grams chloral in lOcc benzene were added. The weights 
are in the proportion of one molecule to one molecule. The 
mixture was boiled under a reflux condenser for |three hours, 
filtered from a small precipitate and then cooled. A crystal- 
line deposit, weighing 5.0 grams and melting at 148°-15l°, 
separated. The crystals were large elongated tables, occur- 
ing in clusters. From the filtrate was obtained 3.0 grams of 
material, melting at 145°-150°. Several recrystallizations 
from benzene raised the melting point to 152°. Niementow-
