Abstract

Procedimento per la preparazione d'alchilaril carbonati che comprende far reagire un dialchil carbonato con un alcol arilico monofunzionale in un sistema controcorrente liquido-vapore in cui il vapore all'uscita del sistema, prima di essere riciclato, è trattato per eliminare l'alcol alchilico formatosi come sottoprodotto di reazione.
