Abstract

"PROCESSO PARA PREPARAR ALQUILENO GLICóIS". que inclui a reação de um óxido de alquileno com água na presença de uma combinação de aditivos e de uma resina trocadora de ânions, sendo que a combinação de aditivos compreende dióxido de carbono e uma base, orgânica ou inorgânica, provida em quantidade suficiente para manter o pH entre cerca de 5,0 e 9,0, e com a condição de quando a base for um carbonato ou um bicarbonato, então a resina trocadora de ânions será uma resina trocadora de ânions trimetil benzil amónio. Um método particularmente preferido da presente invenção é reagir óxido de etileno com água na presença de uma resina trocadora de ânions do tipo halogenado ou bicarbonato (por exemplo, resina do tipo DOWEX^ TM^ MSA-1). Algumas vantagens que esta invenção apresenta: provê um tempo de vida desejável e uma atividade catalisadora, minimiza a taxa de crescimento da resina, e provê uma seletividade sustentada desejável para alquileno glicol.
