Abstract

Un proceso para la produccion de por lo menos un compuesto C4 seleccionado entre butano-1,4-diol y gama-butirolactona y tetrahidrofurano, llevándose a caboel proceso por medio de la hidrogenacion en la fase de vapor de un derivado de ácido dicarboxílico C4 seleccionado entre anhídrido maleico y di-(alkiloC1-4)ésteres de un ácido dicarboxílico C4. En este proceso una corriente de vapor que contiene vapor de anhídrido maleico, vapor de agua, y oxidos de carbono, espuesta en contacto en una zona deabsorcion con un primer solvente de alto punto de ebullicion que tiene un punto de ebullicion a presion atmosférica que espor lo menos alrededor de 30sC más alto que aquel del anhídrido maleico. Desde la zona de absorcion se recupera una corriente de gas de desecho que contieneuna primera cantidad de dicho primer solvente orgánico de alto punto de ebullicion que puesta en contacto en una zona de lavado con un segundo solventeorgánico de alto punto de ebullicion que tiene un punto de ebulliciona presion atmosférica que es por lo menos alrededor de 30sC más alto que aquel delanhídrido maleico. Desde la zona de absorcion se recupera una corriente de gas desecho que contiene una primera cantidad de dicho primer solvente orgánico dealto puntode ebullicion que tiene un punto de ebullicion a presion atmosférica que es por lo menos de 30sC mayor que el del primer solvente orgánico de altopunto de ebullicion. El gas de desecho lavado, que proviene de la zona de lavado es purgado. La solucionresultante del primer solvente orgánico de alto puntode ebullicion con el segundo solvente orgánico de alto punto de ebullicion es tratada para recuperar el primer solvente de alto punto de ebullicion pararecirculacion en la zona de absorcion, mientras que el residuo resultante del segundo solvente de alto punto de ebullicion es recirculado hacia la zona delavado. El anhídrido maleico en la solucion proveniente de la zona de absorcion es convertido, si es necesario, en un éster di-(alkilo C1-4)de ácido maleico oácido fumárico. La solucion del derivado dicarboxílico C4 en el primer solvente de alto punto de ebullicion es puesto en contacto con una corriente gaseosa que
