i go ?] Wheeler — The Condensation of Chloral 101 
after several recrystallizations from glacial acetic acid. 
Determinations of carbon, hydrogen and nitrogen give very 
satisfactory figures for a monobrom compound. A study of 
its constitution is under way. Chlorine gives a similar reac- 
tion. The product, crystallizing in long colorless needles, 
melts at 93° after recrystallization from glacial acetic acid. 
Analysis indicates a monochlor derivative. These bodies will 
be described in a later paper.

With W. S. Dickson. Two molecules (12. 3g) of o-anisi- 
dine were dissolved in 50cc benzene and one molecule (7.3g) 
of chloral were added. After warming a short time on the 
steam bath a separation of colorless needles occurred. These 
decomposed at about 215° and weighed 0.05g. On concen- 
tration of the filtrate in a dessicator a mass of fern-like crys- 
tals was obtained mixed with a thick liquid. After filtering 
the crystals were pressed on a porous tile. The product was 
white, melted at 112°-114° and weighed 9.7 grams. On re- 
crystallizing from benzene the melting point was raised to 
121°. The thick liquid finally solidified, considerably in- 
creasing the yield. 
Analysis: 
0.2000 gram substance gave 0.2294 gram AgCl. 
1.0000 gram substance gave 0.073 gram nitrogen (Kjel- 
dahl).
