procedure for the hydrolysis reaction of ethyl cinnamate with water to form cinnamic acid?
Homework Answers
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 a resulting liquid.

Hydrolysis of Polyethylene Terephthalate Although you used a base-catalyzed procedure for this hydrolysis, acid catalysis also works well (as discussed in the text above). Draw a complete step-by-step mechanism showing how acid catalysis would promote the reaction. Would a work-up be required after hydrolysis? If so, provide a proposed work-up.

Check Your Learning Ethanol and acetic acid react and form water and ethyl acetate,the solvent responsible for the odor of some nail polish removers. 2 15 When 1 mol each of C2H5OH and CH3CO2H are allowed to react in 1 L of the solvent dioxane, equilibrium is established when mol of each of the reactants remains. Calculate the equilibrium constant for the reaction. (Note: Water is not a solvent in this reaction.)
