Actimi of Sodium and Amylic Iodide upon Acetic Ether. 



For this reaction the compounds of sodium derived from acetic ether were prepared 

 as before, and were then submitted to the action of amylic iodide for several hours at 

 the boUing-point of the mixture. When the sodium had all become converted into 

 iodide, water was added and the supernatant liquid decanted. We reserve a complete 

 description of this liquid for our next communication, and will here confine ourselves 

 to the separation from it of oenanthylic acid, which was obtained as follows : — The crude 

 product, after drying over calcium chloride, was submitted to rectification, and the 

 portion boiling between 170° and 190° C. collected apart and decomposed by ebullition 

 with alcoholic potash. By this treatment we destroyed any ethylic amylacetone carbo- 

 nate and ethylic diamylacetone carbonate that were present, and obtained a potash-salt 

 of an acid derived from acetic acid by the substitution of one atom of amyl for one of 

 hydrogen. The potash-salt thus formed was distilled with excess of sulphuric acid 

 diluted with a large quantity of water. Upon the distillate there floated an oily acid, 

 possessing an odour resembling oenanthylic acid. This acid was converted into an 

 ammonia-salt, from which a silver-salt was prepared by precipitation. After being well 

 washed with cold water, this salt yielded the following numbers on analysis : — 



•2423 grm. gave -3159 grm. carbonic acid, -1204 grm. water, and -1108 grm. silver. 



These numbers agree well with the formula of silver amylacetate or oenanthylate.

We have also examined the barium-salt, which is an amorphous soapy substance. 

 Dried at lOC^C, -2715 gim. gave -1599 grm. barium sulphate, corresponding to 34-62
