MoNnNOCHLORSALICYLAMIDE 
C, H, Cl1OH CON H.. 
Fusing point 222°-223° C. 
Produced by heating Methylmonochlorsalicylate with an excess of alco- 
holic ammonia in a sealed tube. The tube was kept in the oven for twelve 
hours, it was then removed, and the alcoholic solution strongly concen- 
trated upon a water bath. When the liquid cooled a mass of needle-like 
crystals separated out. 
When pure the compound fuses at 222°-223° C. Very soluble in warm 
alcohol. 
When the alcoholic ammonia was poured upon the ether the liquid as- 
sumed a beautiful pale blue fluorescence. Upon heating this entirely dis- 
appeared.

MONOCHLORNITROSALICYLAMIDE. 
}, H, NO, C1O H CON H,,. 
Fusing point 192° C. 
This compound shows to what extent the presence of the VH, group in- 
fluences the introduction of new radicals. The ordinary monochlorsali- 
cylic acid when treated with fuming nitric acid does not yield nitrochlor- 
salicylic acid as would be expected, but the carboxy] group breaks up and 
chlordinitrophenols result. To obtain monochlornitrosalicylic acid the 
chlorsalicylic acid must be treated with nitric acid very strongly diluted 
with acetic acid. When chlorsalicylamide, however, is dissolved in fuming 
nitric acid but one product is obtained—the above mentioned—Monochlor- 
nitrosalicylamide. The stability imparted to the compound by the amide 
group allows the reaction to occur without any decomposition.
