Procés de fabricació del BHT

Abstract

L’objectiu del projecte és avaluar, de manera teòrica, la viabilitat industrial del procés de fabricació del 2,6-ditert-butil-4-metil-fenol, conegut com BHT, a partir de fenol. S’estudien les diverses vies de reacció possibles i es desenvolupa el procediment industrial de l’òptima. L’esquema general consta de dos processos: El primer procés explica la formació del 2,6-ditert-butil-fenol, conegut com 2,6-DTBF, constituït per les quatre etapes següents: - Formació del catalitzador - Reacció de butilació - Rentat post-reacció - Destil·lació a buit. I el segon procés explica com passar del 2,6-DTBF al BHT mitjançant les tres etapes següents: - Reacció de Mannich - Hidrogenòlisi - Destil·lació a buit. Es conclou que el procés de fabricació de BHT a partir de fenol és viable. Del primer procés,es disposa d’unes instal·lacions en operació que en garanteixen la viabilitat industrial. Pel segons procés es recomana fer proves experimentals per determinar el catalitzador més adequat per la hidrogenòlisi i veure si es necessària la posterior etapa de destil·lació a buit, a més de seguir avaluant la viabilitat del procés en altres aspectes.
