ON A NEW CLASS OF ALCOHOLS. 
56H 
solution of potassa, when assisted by heat, decomposes this ether rapidly, producing 
allylic alcohol and an alkaline butyrate. 
On analysis this compound afforded the following results : — 
I. 0-400 grm. of substance gave 0-966 grm. of carbonic acid and 0-345 grm. of water. 
II. 0-450 grm. of substance yielded I-08I grm. of carbonic acid and 0-384 grm. of water. 
These numbers may be translated into the formula

Valerate of Allyl. 
Valerate of silver comports itself with iodide of allyl exactly like the acetate and 
butyrate : powerful reaction, attended by separation of iodide of silver, and production 
of an ethereal liquid which may be obtained pure by repeated rectification over fresh 
quantities of valerate of silver, washing with slightly alkaline water, and digestion over 
chloride of calcium. 
Thus prepared, valerate of allyl is a colourless liquid which boils at 162°, and the 
aromatic odour of which recalls that of valerate of ethyl. It is lighter than water, inso- 
luble in this menstruum, but readily dissolved by alcohol and ether. The vapour burns 
with a luminous flame. 
0-384 grm. of substance gave 0-949 grm. of carbonic acid and 0-350 grm. of water.

Benzoate of Allyl. 
Benzoate of allyl may be obtained either by the action of chloride of benzoyl on 
allyhc alcohol, or by the action of iodide of allyl on benzoate of silver. 
It is a nearly colourless liquid with a tinge of amber, heavier than water, in which 
fluid it is insoluble ; it possesses an aromatic odour similar to that of benzoic ether, and 
boils at 228 C°. Alcohol, wood-spirit, and ether dissolve it freely. 
A boiling aqueous solution of potassa decomposes it, reproducing allylic alcohol and 
benzoic acid which unites with the alkali.
