Action of Iodide of Amyl upon Amylamine and upon Ammonia. 
Oxide of Tetramylammonium. 
A mixture of triamylamine and iodide of amyl solidifies after two or three days’ 
ebullition to a solid, somewhat fat-like mass of iodide of tetramylammonium. A 
similar effect is produced by boiling- an excess of iodide of amyl with a concentrated 
solution of ammonia. This reaction, however, takes place very slowly ; in fact, the 
diminution of affinities characterizing the amyl- compounds in general was in none of 
these cases more marked. After two or three days’ ebullition the volume of the 
ether appeared scarcely diminished ; but then a gradual change occurred, the heavy 
amyl-compound rising and floating upon the solution of the new iodide which was 
formed. After a fortnight’s ebullition the aqueous layer began to solidify, when 
allowed to cool ; but even after keeping the mixture for a period of three weeks in 
ebullition, on opening the boiler-tube the reaction was found to be far from complete. 
The semi-solid mixture thus obtained was subjected to distillation, first alone, in 
order to recover the iodide of amyl not acted upon ; then with potassa, to separate 
ammonia and the lower amyl-bases. The alkaline liquid contained a small quantity 
of iodide of tetramylammonium in solution, which crystallized on cooling in fat-like 
leaves ; the larger quantity, however, of this substance collected at the bottom of 
the vessel in form of a heavy oil, which solidified on cooling to a hard mass of the 
appearance of stearin. 
The new iodide resembles in its general properties the corresponding compounds 
I have previously described. Like them it is soluble, but only with difficulty, in 
water, forming a most intensely bitter liquid, and reprecipitated from this solution in 
the crystalline form by the addition of the alkalies. On drying, the iodide assumes 
a slightly yellowish tint. 
0-3890 grm. of the iodide gave 0-2130 grm. of iodide of silver.
