Ryan and Dillon — On Higher Tertiani Alcohols. 245 



obtained on coolinpf was mixed in a mortar with about ten times its weight of 

 finely-powdered potash-lime, and the mixture was introduced into a hard glass 

 test-tube. The tube was connected with a Topler pump, exhausted of air, and 

 heated in a mercury bath. The temperature was slowly raised to 220°; and at 

 this temperature a considerable quantity of water came of from the mixture. 

 After half an hour the temperature was raised to 250° 0. ; and the heating was 

 continued for another half hour. No gas was evolved. The tube was then 

 allowed to cool, and the contents were extracted with ether. 0'6 gramme of 

 extract was obtained, which melted at .34-35° C. (the melting-point of the 

 original alcohol) and did not decolorize bromine water. 



II. 1'208 gramme of the alcohol was treated as above; but the tempera- 

 ture was raised to 300° C, and the heating was continued for several hours. 

 The ether extract yielded 0'2 gramme of a yellowish oil, which decolorized 

 bromine water. 



Action of Potash-Lime on Diphbnyl-Heptadecyl CARBmYL. 



About 1 gramme of the alcohol was mixed in a mortar with powdered 

 potash and potash-lime, and the mixture was introduced into a hard glass 

 test-tube. The tube was heated to 300° C. in a metal bath. On extraction of 

 the residue with alcohol a product was obtained which decolorized bromine 

 water.
