Abstract

Procedimento per la preparazione in discontinuo di alchilaril carbonati che comprende:a) far reagire un dialchil carbonato con un alcol arilico monofunzionale in un recipiente di reazione mantenuto in condizioni operative;b) trattare i vapori formati durante la reazione per eliminare l'alcol alchilico formatosi; e c) riciclare i vapori così trattati al fondo del recipiente di reazione.
