Abstract
Patente de Invenção: <B>"PROCESSO CONTìNUO PARA EFETUAR REAçõES DE GáS - LìQUIDO"<D>. A presente invenção refere-se a um processo contínuo para a produção de poliadutos de óxido de alquileno em um iniciador de cadeia, com pelo menos um hidrogênio ativo. O processo é caracterizado pelo fato de que o mesmo compreende as etapas de (a) proporcionar n unidades de reação, constituídas por um reator tubular (11), e um trocador de calor (14) a jusante do reator tubular (11); (b) suprir o iniciador de cadeia preaquecido e o óxido de alquileno para o reator da primeira unidade de reação; (c) reagir o iniciador de cadeia com óxido de alquileno para ser obtida uma primeira mistura; (d) resfriar a primeira mistura por meio de um trocador de calor (14); (e) alimentar o reator da unidade de reação que se segue, com a mistura resfriada e com o óxido de alquileno; (f) repetir o procedimento até a última unidade de reação e em seguida descarregar a mistura que contém o produto desejado.
