The remaining ethoxyformamidine was dissolved in 4 molecules 

 dilute hydrochloric acid and treated, in the cold, with 1 molecule of 

 sodic nitrite.* A copious evolution of nitrogen is noticed, and after 

 standing for thirty minutes the solution is extracted with ether, and 

 the ethereal solution washed with dilute sodic hydrate and then dried 

 with calcic chloride. An oil is obtained which contains much chlorine, 

 and seems to boil without decomposition, and at higher temperatures 

 possesses a very sharp odor. It is very probable that it consists of 

 ethoximformylchloride, 



C2H50N:C^j 



On heating the oil, which is soluble in water, with concentrated caustic 

 alkalies, a strong smell of isonitrile is observed, which can only be due 

 to the formation of ethylcarbyloxime. Ethoximformylchloride seems, 

 however, in comparison with formylchloridoxime, to be remarkably 

 stable, and is split, on treatment with alkalies, chiefly into formic acid, 

 ethoxylamine, and potassic chloride. 



The Action of Chloroform and Alcoholic Potash on a Benzylhy- 



droxylamine. 



The esters of carbyloxime ought, however, to be obtained most easily 

 from M alkylated hydroxylamines by means of Hofmann's reaction, 



RONH, + CHClg + 3 KOH = RON : C + 3 KCl + 3 HjO. 



On adding a mixture of a benzylhydroxamine f (10.4 grams) and 

 chloroform (17.3 grams) to a solution of 19.2 grams potassic hydrate 

 in 70 grams alcohol, an energetic reaction takes place, and a strong 

 smell of isocjanide is noticed. Benzylcarbyloxime, C7H7ON : C, has, 

 however, been formed only in minute quantities, and 7 grams unchanged 

 a benzylhydroxylamine were recovered. The reason for this seems 

 to me to be due to the fact that the intermediate product,
