Abstract
La presente es un proceso para purificar 1,3-propanodiol (PDO) mediante una secuencia de destilación invertida que comprende: a) extraer opcionalmente agua u otros solvente de la mezcla de 1,3-propanodiol crudo; b) destilar la mezcla de 1,3-propanodiol crudo en condiciones que maximizan la separación de componentes de la mezcla que son más pesados que el 1,3-propanodiol del 1,3-propanodiol y los que son más livianos que el 1,3-propanodiol; c) extraer una corriente que contenga al menos la mayor parte del 1,3-propanodiol y al menos algunos de los componentes de la mezcla que son más livianos que el 1,3-propanodiol; y d) destilar la corriente de c) para separar el 1,3-propanodiol de los componentes en la corriente que son más livianos que el 1,3-propanodiol y cualesquiera de los componentes residuales que son más que el 1,3-propanodiol.
