NOVELTY - Glycerol or glycerite is reacted with olefin or alcohol under the action of a catalyst which is functionalized graphene catalyst formed by connecting acidic organic functional group with catalytic activity onto graphene as support to obtain glycerol ether. USE - Preparation of glycerol ether (claimed). ADVANTAGE - The method efficiently provides glycerol ether with high reaction activity and polyether selectivity, under mild reaction condition.
