Abstract

PROCEDE D'INTRODUCTION D'ACIDE TEREPHTALIQUE SEC DANS UN REACTEUR QUI PEUT CONTENIR DU GLYCOL ET ETRE SOUS UNE PRESSION ET A UNE TEMPERATURE ELEVEES. IL CONSISTE A FORMER UNE SUSPENSION D'ACIDE TEREPHTALIQUE DANS UN GAZ TEL QUE L'AZOTE ET A INTRODUIRE CETTE SUSPENSION DANS LE REACTEUR.PROCESS FOR INTRODUCING DRY TEREPHTHALIC ACID INTO A REACTOR WHICH MAY CONTAIN GLYCOL AND BE UNDER HIGH PRESSURE AND TEMPERATURE. IT CONSISTS OF FORMING A SUSPENSION OF TEREPHTHALIC ACID IN A GAS SUCH AS NITROGEN AND INTRODUCING THIS SUSPENSION IN THE REACTOR.
