12 ART. 14. T. SUZUKI : THE OXIMES AND 



cipitate, difficut to filter and wash without loss. The yield was 

 about 609» of the theoretical amount. 



This oxime is slightly soluble in alcohol and acetone, and 

 almost insoluble in other ordinary solvents. Acetone is the only 

 solvent that can be employed for the purpose of recrystallisation. 

 From this menstruum the oxime crystallises out on evaporation 

 in thin plates, the crystals retaining a part of the solvent, which 

 can be driven off on heating to 100°. There is practically 

 no loss on recrystallisation. On heating this compound in a 

 capillary tube it decomjDOses suddenly at 210° in the same 

 manner as the meta-oxime, and the temperature can be used 

 for the purpose of identification. Like the latter it changes 

 into a viscous substance when boiled with alcohol, and, indeed, 

 so quickly that crystals are hardly obtainable from an alcoholic 

 solution. The oxime dissolves easily in caustic alkalies, and 

 is repreci pita ted on acidulatiou. The reactions with zinc and 

 caustic soda, ammonia, and nitric acid are almost analogous to 

 those of the meta-compound. 



It is possible and even likely that this oxiine has also a 

 double molecular formula, but the molecular weight determina- 

 tion was not attempted on account of its slight solubitity in 

 acetone.
