Eighty one grams <strong>of</strong> salicylic acid. 47 grams<br />
<strong>of</strong> phenol and 25 grams <strong>of</strong> phosphoric pentoxide were<br />
heated in an autoclave for forty five minutes at<br />
a maximum temperature <strong>of</strong> 130°C« and a pressure <strong>of</strong><br />
57 pbs. per in. 2 Salol, together with resinous<br />
impurities* was formed'<br />
WITH ACID SULFATES.<br />
Eighty grams <strong>of</strong> sodium salicylate, 47 grams<br />
<strong>of</strong> phenol and 60 grams <strong>of</strong> sodium bisulfate were<br />
heated together in a porcelain evaporating dish<br />
for two hours. There was a great tendency for the<br />
volatilization <strong>of</strong> phenol, even at low temperatures-<br />
The resulting product showed only traces <strong>of</strong> salol.<br />
GENERAL INFERENCES.<br />
The foregoing reactions with phosgene in the<br />
presence <strong>of</strong> benzol. PgOg under pressure. KaHSC>4<br />
in the open, have not given promising results.<br />
T^is may be due either to the particular reagents<br />
used, or to the conditions under which the<br />
operations were carried out*<br />
