Patent

CA 2417940

A process is disclosed which provides for the reduction of phenylacetylene levels in styrene monomer feedstreams, which process utilizes a normal styrene inhibitor additive, such as an hydroxylamine, injected into the styrene monomer feedstream immediately upstream of the phenylacetylene reduction reactor.

On divulgue un processus permettant la réduction des concentrations de phénylacétylène dans l'alimentation en monomères de styrène; ce processus fait appel à un additif inhibant le styrène normal, comme une hydroxylamine, que l'on injecte dans le circuit d'alimentation en monomère de styrène tout de suite en amont du réacteur de réduction du phénylacétylène.
