Abstract
The invention relates to a process for preparing a cinnamate ester comprising forming a reaction mixture of a styrene compound, an alcohol and a catalyst in a reactor; blowing a feed gas mixture of carbon monoxide, oxygen and an inert gas into the reaction mixture through at least one feed port; collecting a discharge gas flowing from the reactor and passing the gas through a condenser to form a condensate; recirculating the condensate into the reactor; blowing into the reaction mixture through at least one feed port other than the feed port(s) for the feed gas mixture, a gas selected from the groups consisting of the discharge gas and an inert gas; and isolating the cinnamate ester from the mixture.
