Abstract

PROCEDIMIENTO DE OBTENCION DE TETRAHIDROFURANO. CONSISTE EN REDUCIR UN ALDEHIDO ETER DE FORMULA GENERAL (I), Y ESCINDIR EL HIDROXI-ETER RESULTANTE, BAJO CONDICIONES DE DESHIDRATACION. EL ALDEHIDO-ETER (I) ES PRODUCIDO POR REACCION DE UN ALIL T-ALQUIL O -CICLOALQUIL ETER, BAJO CONDICIONES DE HIDROFERMILACION CON MONOXIDO DE CARBONO E HIDROGENO, EN PRESENCIA DE UN CATALIZADOR DE HIDROFERMILACION. LA ESCISION DEL HIDROXI ETER ES EFECTUADA EN PRESENCIA DE UN CATALIZADOR ACIDO ELEGIDO ENTRE LOS ACIDOS ACUOSOS Y LAS RESINAS DE INTERCAMBIO IONICO ACIDAS, ARCILLAS ACIDAS, ALUMINA ACIDA, ALUMINIO-SILICATOS ACIDOS Y SILICE. *FORMULA*
