Abstract

Настоящее изобретение относится к способу удаления гидроксипропана из потока сырого продукта гидрогенизации глицерола, содержащего 1,2-пропандиол и гидроксипропанон в качестве примесей, причем заявленный способ включает: (а) при необходимости конденсацию потока сырого продукта и (б) обеспечение взаимодействия фазы сырого продукта в жидкой среде с потоком газа, содержащего водород, в присутствии гетерогенного катализатора при подходящем температурном режиме и давлении таким образом, что гидроксипропанон, присутствующий в потоке сырого продукта, превращается в нужный пропандиол.
