Title:
ADSORBENT AND PREPARATION METHOD THEREFOR, METHOD FOR PURIFYING HEXAMETHYLENEDIAMINE, AND METHOD FOR PREPARING ORGANIC DIAMINE AND DEVICE USED THEREIN
Document Type and Number:
WIPO Patent Application WO/2023/011117
Kind Code:
A1
Abstract:
The present invention provides an adsorbent and a preparation method therefor, a method for purifying hexamethylenediamine, and a method for preparing organic diamine and a device used therein. The adsorbent comprises a carrier and surface molecules loaded on the carrier. An imprinted cavity is formed among the surface molecules, and is matched with an azepine compound. The adsorbent has a short preparation process flow, and is suitable for industrial production. In addition, the adsorbent also has a specific adsorption effect on the azepine compound, and can be well applied in the adsorption and separation of trace impurities in hexamethylenediamine, thereby significantly improving the product purity of hexamethylenediamine.
