Abstract
"PREPARAçãO SELETIVA DE O-ALQUILFENóIS". Em um processo para preparação de o-alquilfenóis por reação de fenol com um alcanol a temperatura elevada na fase gasosa na presença de um catalisador de óxido metálico ocorre a reação em pelo menos duas etapas, nas quais ajusta-se a proporção molar de alcanol/fenol em cada etapa de reação a um valor de cerca de <243> 0,4; obtém-se um aumento visível da seletividade para o o-alquilfenol.
