摘要:
A modified montmorillonite clay is prepared by heating it, impregnating it with an organic liquid, acid-activating it with a strong acid, and then washing it with water until it is substantially free of acid anions. The modified clay is useful as a catalyst, particularly for the preparation of tetrahydrofuran/alkylene oxide copolymers.
