On placing ina freezing mixture at —20°O. it did not. 
solidify, and was recovered uncbanged after boiling for 
several hours with 100% (crystallisable) formic acid. No 
solid derivative from the addition of bromine at — 20° C. in 
either dry ether or carbon tetrachloride solution could be 
obtained. The formula appears to be Ci1H1203 as indicated 
by the following combustion and molecular weight results, 
V1Z:— 
(1) 0°1222 gm. gave 0°3086 gm. CO. and 0°0696 gm. H.O 
C=68°87%, H=6 33%. 
(2) 0°1354 gm. gave 0°3410 gm. CO2 and 0°0755 gm. H.O 
C=68'68%, H=6°2%. 
(3) 0°1060 gm. gave 0°2674 gm. COz and 0'0624 gm. HO 
C= 68°8%, H=6°54% 
(4) 0°1271 gm. gave 0°3206 gm. CO, and 0°0756 gm. H,O 
O=68°8%, H=6°61%. 
O11Hi203 requires C=68°75, H =6°25. ~ 
Molecular weight determinations.—(a) A molecular 
weight determination by the Landsberger boiling point 
method using acetone as solvent gave the following result: 
1°0434 gram iu 21 c.c. acetone elevated the boiling point 
0°6> OC. -MoOWt: = 184: | 
(b) A determination by the cryoscopic method using 
benzene resulted as follows:—0°3160 gram in 10 grams 
benzene lowered the freezing point 0°848° OC. M.Wt.=186°3.. 
OyH1203 requires 192. | 
Determination of Methoxy groups.—The percentage of 
methoxyl (OCH,) obtained in two determinations by the 
method of Zeisel were 15°63% and 15°4% respectively. 
O1Hi203 : OCH, = 16°147%. Only one methoxy group is. 
apparently present. 
Oxidation with Potassium Permanganate.—The oxida-- 
tion of the phenol ether by means of alkaline potassium 
permanganate solution at 0° C. appears to have taken a
