Nitroso Compounds of Fatty Series. Part I. 

 By the action of nitrous acid on acetoacetic ester a compound Ce H 9 

 NO 4 was produced. It was liquid even at 25 below zero but after 

 standing some months some of it crystallized. Acetyl chlorid has no 

 action on it which is one proof of the formula CH 3

Methyl acetoacetic ester treated with nitrous acid gives nitroso-methyl 

 acetone, CH 3 CO CH (CH 3 ) NO, which forms white crystals soluble in 

 alcohol, ether and chloroform ; it melts at 74, and boils at 185 186 

 undecomposed. It is the first nitroso compound whose vapor density 

 has been determined. Kthyl-acetoacetic ester treated with nitrous acid 

 gives nitroso-ethyl-acetone, CH 3 CO CH (C 2 H 5 ) NO, crystals which 

 are soluble in alcohol, ether and chloroform and slightly soluble in 

 water, it melts at 53-55

 Action of Sulfuryl Chlorid on Acetoacetic Ester. 



This action produces two compounds according to the proportions of 

 the chlorid used. If an excess of sulfuryl chlorid act upon acetoacetic 

 ester, CH 3 CO C C1 2 CO 2 C 2 H 5 , is formed. If molecular quantities of 

 the two substances are taken, CH 3 CO C HC1 CO 2 .C 2 H 5 , is formed 

 which is a colorless liquid boiling at 193 to 195. Its specific gravity is 

 1.19 at 14. When saponified mono-chlor-acetic ester is produced.

Nitroso Compounds of the Fatty Series. Part II. 

 By different manipulations of nitrous acid and methyl-acetoacetic 

 ester three bodies were obtained :
