Abstract

"PROCESSO PARA PREPARAçãO DE éTERES". Um processo para a preparação de éteres inclui as etapas de: proporcionar uma carga de alimentação contendo iso-olefinas selecionadas do grupo consistindo de C5-iso-olefinas, C6-iso-olefinas e suas misturas; misturar a carga de alimentação com álcool alquílico de modo a proporcionar uma carga de alimentação de reação, alimentar a carga de alimentação de reação em uma zona reatora na presença de um primeiro catalisador de eterificação por meio do qual o álcool alquílico reage com as iso-olefinas para formar alquil-terc-alquil-éteres de maneira a proporcionar uma carga de alimentação intermediária contendo os éteres e iso-olefinas e álcool alquílico não reagidos; alimentar a carga de alimentação intermediária em uma coluna de destilação catalítica possuindo um segundo catalisador de eterificação definindo uma zona catalítica; misturar álcool alquílico adicional na carga de alimentação intermediária de modo a formar azeótropos de álcool alquílico com as iso-olefinas não-reagidas sem formar azeótropos de álcool alquílico com os éteres por meio do qual a zona catalítica está substancialmente livre de éteres e as iso-olefinas não reagidas reagem com o citado álcool alquílico na zona catalítica para formar alquil-terc-alquil-éteres adicionais.
