Abstract

Processo per il recupero dei residui del fondo colonna prodotti dalla distillazione del glicole etilenico risultante da un processo di produzione di poliesteri aromatici consistente nel trattare detti residui con un mono-alchil estere aromatico e nel sottoporre a distillazione il prodotto di reazione.
