Abstract

"PROCESSOS PARA A PREPARAçãO DE CATALISADORES DE CIANETOS DUPLOS METáLICOS (DMC)". A presente invenção refere-se a processos para fabricar catalisadores de cianetos duplos metálicos (DMC), controlando simultaneamente a alcalinidade do sal metálico de transição, a razão molar de água para cátions totais, a razão molar de ligante para cátion de metal de transição, a razão molar do ânion do sal metálico para o ânion cianeto metálico, e a presença de um ligante complexante polimérico durante a etapa de precipitação do catalisador. Os catalisadores substancialmente amorfos produzidos pela presente invenção são altamente ativos e podem encontrar uso na produção de polióis.
