Abstract

"PROCESSO PARA PREPARAR POLIéTER POLIóIS E POLIóIS PREPARADOS COM ESTES". Poliéter polióis adequados para uso na preparação de espumas de poliuretano rígidas são preparados por um processo utilizando catalisadores de imidazol. Os catalisadores de imidazol não perdem reatividade a altas temperaturas e podem ser usados a temperaturas mais altas para preparar polióis decrescendo assim o tempo de residência e o consumo de energia em processos de produção de polióis."PROCESS TO PREPARE POLYETHER POLYOLES AND POLYOLES PREPARED WITH THESE". Polyether polyols suitable for use in the preparation of rigid polyurethane foams are prepared by a process using imidazole catalysts. Imidazole catalysts do not lose reactivity at high temperatures and can be used at higher temperatures to prepare polyols thereby decreasing residence time and energy consumption in polyol production processes.
