Preparation of cinnamic acids |
| abstract |
A process is disclosed which prepares a cinnamic acid from a cinnamate ester by starting the hydrolysis reaction of the cinnamate ester with an alkali by use of water as a solvent in a heterogeneous binary-phase liquid system to obtain an aqueous alkaline solution of an alkali cinnamate and precipitating the cinnamic acid by conducting an acidifying reaction of said aqueous alkaline solution with a mineral acid so as to keep a pH value of not more than 4 in the resulting liquid. |
