(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).
Benzene is insoluble in water due to its non polar character. But its solubility is 0.8 g/100 ml at 25 degrees c which is also very low NH3, ammonia, is soluble in water due to the formation of NH4+ and OH-with water .Its solubility is 89.9 g/100 ml (0 Â°C).Source(s): See solubility in water in www.wikipedia.org for reference.ut its solubility is 0.8 g/100 ml at 25 degrees c which is also very low NH3, ammonia, is soluble in water due to the formation of NH4+ and OH-with water .Its solubility is 89.9 g/100 ml (0 Â°C).
