Cerotone Oxime. — This compound is new. It was prepared as follows : 

 1 gram of ketone was dissolved in 150 c.c. of amyl alcohol, and one and 

 a half times the theoretical quantity of hydroxylamine hydrochloride, 

 with an excess of caustic potash to decompose the hydrochloride, was 

 added, and the alcohol then boiled under a reflux condenser for eight 

 hours. It was found that unless prolonged boiling took place a poor yield 

 of oxime was obtained. The hot solution was then filtered from the in- 

 organic salts, and the filtrate allowed to crystallize. The crystals were 

 filtered off, and recrystallized from ethyl acetate. 



The oxime thus obtained melted at 77°, and the melting-point was 

 not changed by further crystallization. The oxime is easily soluble in 

 hot ethyl acetate and amyl alcohol, but is only sparingly soluble in hot 

 alcohol. The crystals from the ethyl-acetate or motor-spirit crystalliza- 

 tions are groups of radiating needles.

Henpenteeonimtc* 26 01. 



This secondary alcohol is new, and was obtained by reducing the ketone, 

 dissolved in amyl alcohol, with metallic sodium. 0-3 grams of cerotone 

 were dissolved in 150 c.c. amyl alcohol and boiled under a reflux con- 

 denser, while, at intervals, small pieces of sodium, of total weight 2 grams, 

 were added over a period of five hours. The solution thus obtained was 

 shaken out with water in a separating-funnel. The solid was filtered off 

 and crystallized from ethyl acetate. The melting-point of ihe alcohol 

 thus obtained was 97°, and was unchanged by further crystallization. 



Henpentecontyl Acetate. — This compound was obtained from the above- 

 mentioned secondary alcohol by boiling it with a large excess of acetic 

 anhydride under a reflux condenser for six hours. 



The alcohol gradually dissolved in the acetic anhydride, indicating that 

 acetylation was taking place. The solution was filtered while hot. and 

 the filtrate, on cooling, deposited the acetate as a white solid. This was 

 recrystallized from acetic anhydride, and after drying over caustic potash 

 in a vacuous desiccator, melted at 60-5-61-5°. The melting-point was un- 

 changed by further crystallization.
