with animal charcoal, filtered, and cooled. The colourless needles which were 

 finally obtained melted at 44° C, and when heated with soda- lime evolved 

 aniline. 



0-2855 g. substance gave 81 c.c. N. at 21° C. and 762 mm.p. N = 3-24. 



C3„Hj5NOo requires N = SIO. 



It is easily soluble in benzene, acetone, ether, light petroleum, chloroform, or 

 warm alcohol. 



Phenylixntadecyl Garhinol CeHsCHOHCsHai. By reduction of phenyl- 

 pentadecyl ketone in alcoholic solution with sodium as described under 

 p-tolylpentadecyl carbinol the colourless, crystalline phenylpentadecyl car- 

 binol was obtained. It melted at 53° C, and dissolved easily in petroleum 

 ether, acetone, or benzene. 



0-2167 g. substance gave 0-6566 g. CO, and 0-2296 g. H^O. C = 82-6, H = 12-3. 



C,,H3bO requires C = 83-0, H = 12-0. 



Phenylheptadecyl Carhinol CeHs'CHOH-CiiHjs. 3-5 grammes of phenyl- 

 heptadecyl ketone gave 3 grammes of the carbinol, which, when recrystallized 

 a few times from alcohol, melted at 59° 0. 



0-2112 g. substance gave 0-6424 g. CO, and 0-2271 g. HoO. C = 82-95, H = 11-95. 



C,iH«0 requires C = 82-2, H = 1214. 



It is easily soluble in chloroform, benzene, or ether, and moderately soluble 

 in alcohol, petroleum ether, or acetone. 



Its acetate was obtained in the form of needles, which melted at a low 

 temperature, and had a sweet odour, by heating the alcohol with sodium 

 acetate and acetic anhydride. 



A saponification with standard alcoholic potash showed again that the 



ester was somewhat impure. 



N 

 0-4719 g. acetate required 2-15 c.c. <, KOH for complete hydrolysis. 



E.No. = 127. 

 C,cH,,0, requires E.No. = 144.
