Abstract

Invenţia se referă la un procedeu de obţinere a bis(4-hidroxiaril)alcanilor.Procedeul de obţinere a bis(4-hidroxiaril)alcanilor din aducţii bis(4-hidroxiaril)alcanilor şi compuşilor hidroxiaromatici prevede următoarele faze:a) prin topitura unui aduct al bis(4-hidroxiaril)alcanului şi a unui compus hidroxiaromatic la temperatura de 150…230°C se trece un gaz inert, totodată, fluxul de gaz inert elimin compusul hidroxiaromatic din topitură;b) compusul hidroxiaromatic se înlătură din fluxul de gaz inert prin condensare;c) fluxul de gaz inert se purifică, se comprimă şi se reintroduce în faza (a).Bis(4-hidroxiaril)alcanii obţinuţi prin procedeul solicitat se caracterizează printr-un grad minim de colorare, precum şi prin puritate înaltă, datorită reducerii conţinutului de compuşi hidroxiaromatici şi de produse de descompunere.
