Abstract

La presente proporciona un proceso para preparar un 1,3-alcanodiol, como por ejemplo 1,3-propanodiol (PDO), a partir de 3-hidroxialdehído, como por ejemplo 3-hidroxipropanal (HPA) que incluye, proporcionar una mezcla de un 3-hidroxialdehído en un disolvente orgánico; extraer en un líquido acuoso una porcion principal de 3-hidroxialdehído para proporcionar una fase acuosa que incluye el 3-hidroxialdehído en mayor concentracion que la concentracion del 3-hidroxialdehído en la mezcla de 3- hidroxialdehído, y una fase orgánica; separar la fase orgánica de la fase acuosa; poner en contacto la fase acuosa con H en presencia de un catalizador de hidrogenacion para dar lugar a una mezcla de producto de hidrogenacion que incluye un 1,3- alcanodiol y agua; separar el agua el 1,3-alcanodiol con un diagrama de evaporacion multiefectivo; reciclar el agua que contiene aproximadamente 50% p o menos de 1,3-alcanodiol en base a la concentracion total de 1,3-alcanodiol y agua a la etapa de extraccion; y recuperar el 1,3-alcanodiol.
