摘要：

A method for separating petroleum hopanoid classes based on the shape and size of their carbon skeletons is demonstrated. The technique is based on the molecular sieving properties of ultrastable Y zeolite (US-Y). This sieve provides a shape-selective window which distinguishes between the various hopanoids. Column chromatography with US-Y zeolite separates the 17-alpha(H)-diahopanes, 18-alpha(H)-norneohopane, 22S 17-alpha(H)-hopanes, 22R 17-alpha(H)-hopanes and the moretanes.
