摘要:
以白炭黑和偏铝酸钾为原料,低碳链饱和醇为添加剂合成了L沸石,并系统研究了甲醇、乙醇、异丙醇、正丁醇、乙二醇和丙三醇对L沸石晶粒尺寸及晶体形貌的影响.实验结果表明:无添加剂合成的L沸石为扁圆柱形,粒径较小；而分别添加少量上述6种醇所得L沸石则均呈扁平蚌状,粒径显著增大,而且结晶度较好；在一定范围内增加乙醇的添加量,依次获得不同形貌的L沸石晶体,但结晶度逐渐降低.
Abstract:
Zeolite L was synthesized by using silica aerogel and potassium aluminate as raw materials and shortcarbon chain saturated alcohols as additives. The effects of methanol，ethanol，isopropanol，butanol，glycoland glycerol on the erystal size and crystal morphology of zeolite L were investigated systematically.Particlesize of zeolite L synthesized without adding additives was small and crystal morphology was flat eylinder. Whenadding small amount of various alcohols，the crystal morphology of the product was flat clam， the crystallinitywas high and particle size of zeolite L increased obviously. Increasing ethanol amount in a certain range，thecrystallinity was decreased and zeolite L with different shapes was obtained.
