Abstract
La presente invención se refiere a un procedimiento de una sola etapa para la obtención de poliaminas preferentemente de elevado peso molecular con grupos amino primarios mediante hidrólisis de compuestos que presentan grupos NCO, en disolventes orgánicos que contienen agua mediante la adición de catalizadores básicos, caracterizado porque se hidrolizan a temperaturas comprendidas entre 40 y 170 grados C a) compuestos que presentan grupos NCO, preferentemente grupos NCO aromáticamente enlazados con un contenido en NCO de 0,5 hasta 40 por ciento en peso, preferentemente prepolímeros NCO, con un contenido de NCO de 1,2 a 25 por ciento en peso, o poliisocianatos modificados con un contenido en NCO de 1,5 hasta 20,5 por ciento en peso, b) con 0,75 hasta 40 moles de agua por equivalente de NCO del componente a), c) en presencia de 0,0001 a 0,099 por ciento en peso, preferentemente de 0,001 a 0,08 por ciento en peso, referido al 100 por ciento en peso del componente a), de hidróxidos o alcoholatos de potasio, rubido o cesio o de 0,0001 a 0,0099 por ciento en peso, preferentemente de 0,001 a 0,008 por ciento en peso de carboxilatos correspondientes al componente a), a modo de catalizadores básicos, d) y, en caso dado, de 10 por ciento en peso, referido al 100 por ciento en peso del componente a), de disolventes orgánicos, polares, miscibles con agua con grupos nitrilo, cetona, sulfóxido o éter y con un margén de ebullición de 56 a 250 grados C, e) con mantenimiento de una fase de reacción homogénea.
