MOLECULAR CONSTITUTION OF THE ORGANIC BASES.

Action of Heat on Oxide of Amylotriethylammonium, 
Oxide of amylotriethylammonium, when subjected to distillation, begins to froth 
as soon as the solution becomes concentrated, after which decomposition rapidly sets 
in. The products of this decomposition are water, an oily substance, and a trans- 
parent inflammable gas. The latter, by the method I have indicated when speaking 
of the decomposition of oxide of tetrethylammonium, was proved to be perfectly pure 
olefiant gas, when the composition of the oily liquid was no longer doubtful. It was 
evident that this substance must be a nitrile-base containing two equivalents of ethyl 
and one equivalent of amyl.

Experiment has entirely confirmed this view. Diethylamylamine — for this is the 
name which appertains to the new compound — has a peculiar, not unpleasant aromatic 
odour, and an analogous somewhat bitter taste, is lighter than water, in which it 
scarcely dissolves, imparting to it a slight but decided alkaline reaction. It com- 
bines with acids less readily than do the bases which occupy a lower position in the 
system. The salts with sulphuric, nitric, oxalic and hydrochloric acids, crystallize 
beautifully, but are deliquescent. Diethylamylamine, when dried over hydrate of 
potassa and rectified, exhibits a perfectly constant boiling-point at 154°C. 
I have fixed the composition of this base, as usual, by the analysis of the platinum- 
salt. This compound is obtained by concentrating a mixture of the hydrochlorate 
with bichloride of platinum, when it shoots into long magnificent orange-yellow 
prisms.
