Abstract

PROCESSO TOLERANTE A ALTO TEOR DE áGUA PARA A PRODUçãO DE POLIéTERES. A presente invenção refere-se a um processo para a produção de um poliéter envolvendo estabelecer condições de oxialquilação em um reator de oxialquilação na presença de cerca de 5 ppm a cerca de 1.000 ppm, com base no peso final do poliéter de um catalisador de cianeto de metal duplo (DMC), introduzir continuamente no reator pelo menos um óxido de alquileno e um iniciador de baixo peso molecular tendo um peso molecular médio numérico de menos que cerca de 300 dáltons (Da) contendo cerca de 200 ppm a cerca de 5.000 ppm de água e acidificado com cerca de 10 ppm a cerca de 2.000 ppm de pelo menos um de um ácido mineral prático inorgânico e um ácido orgânico, e recuperar um produto de poliéter tendo um peso molecular médio numérico de cerca de 200 Da a cerca de 4.000 Da, em que as ppm (partes por milhão) de água e ácido são baseadas no peso do iniciador de baixo peso molecular. O processo inventivo pode possibilitar o uso de iniciadores de baixo peso molecular contendo níveis mais altos de água em níveis mais baixos de catalisador DMC que os processos correntes.
