Abstract

Patente de Invenção: <B>"CONTROLE DE DIARILALCANO PELA FORMAçãO DE PRODUTO NA ALQUILAçãO DE AROMáTICOS POR OLEFINAS USANDO BETA CATALISADORES DE ZEóLITA <D>. A quantidade de um subproduto de diarilalcano indesejável formado em uma reação de alquilação usando um catalisador de zeólito beta, em que uma alimentação de substância aromática reage com uma olefina, é reduzida pelo uso de um diluente alquilaromático em uma quantidade suficiente para que a razão de grupos fenila por grupo alquila correspondente ao reagente olefina que entra no reator seja mantida na faixa de 0,75:1 a 25:1, e a concentração da olefina que entra na reação seja menor que uma quantidade calculada dividindo-se PM~ O~ pela soma de 6,17 PM~ A~ e PM~ O~, em que PM~ O~=peso molecular da olefina e PM~ A~ = peso molecular da alimentação de substância aromática.
