Catalysis and deactivation of montmorillonite K10 in the aryl O -glycosylation of glycosyl trichloroacetoimidates

Xiaoliu LI, Xinhao YAN, Zhiwei LI, Hua CHEN, Pingzhu ZHANG,

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 3, Pages 342-347 doi: 10.1007/s11705-009-0279-1

Abstract: It was found that the catalyst MK10 is deactivated gradually in the recycle glycosylation.The fresh and the deactivated catalysts were characterized by X-ray diffraction (XRD), X-ray photoelectronThe regeneration of the deactivated MK10 by calcination was studied preliminarily.
