Process for producing perfural in high yield using a tungsten catalyst supported on titania |
| abstract |
The present invention relates to a method for producing perfural in a high yield using a tungsten catalyst supported on titania, and specifically, in a method for producing perfural using xylose or hemicellulose as a raw material, Converting the raw material to perfural using a solid acid catalyst having an isopolytungstate supported on a titania support in a reaction medium comprising a critical fluid (step 1) and supercritical fluid in the reaction medium. It provides a method for producing perfural in high yield comprising the step of extracting and separating the perfural by spraying (step 2).n n n The method for producing perfural according to the present invention is to produce perfural using a tungsten-based solid acid catalyst having excellent thermal stability and chemical stability, while having excellent yield and low catalyst loss rate, thereby reducing the production cost of perfural to produce perfural. This can be useful for. |
