Abstract
29 Si Magic-angle-spinning n.m.r. and i.r. spectroscopy, and powder X-ray diffractometry establish that the amount of framework aluminium increases dramatically (by nearly 48%) upon treatment of ultrastable zeolite Y with an aqueous solution of KOH; this affords a ready method of redistributing Si and Al in the framework sites of zeolitic catalysts.Keywords
