Oxalate of Allyl and AllyloxametJian. 
We have previously stated under what circumstances oxalate of allyl is formed, we 
will not therefore recur again to its mode of preparation. Purified by a simple rectifica- 
tion, this compound presents itself as a colourless limpid liquid of a specific gravity of 
1‘05 at 15°’5 C., and boiling constantly between 206° and 207° C. (Bar. 0“’754), 
possessing an aromatic odour recalling that of oxalic ether, with a faint admixture of 
the smell of mustard oil. A similar remark in fact applies to all the allyl-compounds ; 
they smell like the corresponding ethyl-compounds, only somewhat more pungent. 
When mixed with water, oxalate of allyl undergoes gradual decomposition, but it is much 
more rapidly decomposed when boiled with a solution of caustic potassa. Solution 
of ammonia attacks it rapidly, and transforms it into oxamide and allylic alcohol. An 
alcohohc solution of ammonia added with caution so as to avoid the formation of 
oxamide, produces a substance analogous to oxamethan, which, for this reason, we shall 
designate by the name allyloxamethan. This substance separates in magnificent crystals 
when its alcohohc solution is allowed to evaporate spontaneously. 
Potassium and sodium energeticaUy attack the oxalate of allyl, especially with the aid 
of heat, an evolution of carbonic oxide ensues, whilst there passes over on distillation a 
hmpid colourless oil of an aromatic odour, lighter than water ; this is in fact the carbonate 
of allyl. 
The analysis of the oxalate of allyl has furnished the following results : — 
I. 0T79 grm. of substance gave 0’3695 grm. of carbonic acid and 0‘0951 grm. of water. 
II. 0'320 grm. of a second specimen gave 0’662 grm. of carbonic acid and 0T70 grm. 
of water.
