Abstract
The present invention relates to a method including: directly heating a fermentation broth to remove impurities, thereby preparing an organic vapor-phase dehydration feedstock; and continuously subjecting the organic vapor-phase dehydration feedstock to a vapor-phase dehydration reaction. According to the present invention, impurities in a fermentation broth, which have been removed by a multi-step process in the prior art, can be completely removed in a single-step process, and thus the time, cost and energy required for a process for preparing an organic vapor-phase dehydration feedstock from the fermentation broth can be effectively reduced, and the process for preparing the organic vapor-phase dehydration feedstock and a vapor-phase dehydration reaction can be continuously performed in an effective manner.
