(also cinnamic aldehyde, Î²-phenylacrolein), C 6 H 5 CH=CHCHO, a fatty-aromatic unsaturated aldehyde; a colorless liquid with the characteristic odor of cinnamon. It has a boiling point of 252Â°C and a density of 1.110 g/cm 3 (at 20Â°C). It is poorly soluble in water and very soluble in alcohol and ether. Cinnamaldehyde is a component of many essential oils (cinnamon oil and others).
But this I am talking about diethyl ether. The solubility of Ether in water also depends on the type of Ether you are using.

However, dimethyl ether is not at all soluble in water.
