Ethylacetoacetate, when shaken up with yellow oxide of 
mercury, gradually combines with it forming a white amorphous 
powder. This is washed with ether to free it from the excess 
of ester and dried on the water bath. oie substance on 
analysis gave C= 246, H=3'4 and Hg=51 The white 
powder is probably a double compound of neg ester and the 
oxide having the formula 
3HgO . 4CH,CO.CH,COOC,H, 
Theory for the latter demands C = 24°68, H=3°42, Hg=51°4. 
The white powder is insoluble in water. It regenerates the 
ester on shaking up with dilute hydrochloric acid and the oxide 
of mercury goes into solution. 
On warming the white powder with strong caustic potash 
solution the compound breaks up into its components, namely 
HgO and ester, and the latter undergoes hydrolysis, alcohol 
and acetic acid being formed— 
CH,COCH,COOC,H, + 2KOH = 2CH,COOK + C,H,OH. 
The addition of mercuric oxide to the ester and the forma- 
tion of the double compound suggests the possibility of the 
formation of similar double compounds with ketonic esters. I 
am at present engaged in the preparation of similar double 
a aa with other organic substances containing the CO
