摘要:

A型沸石分子筛作为沸石分子筛中经典成员之一,在大学化学课程中均有讲述,但传统的讲授和实验存在学生数量众多、缺乏趣味性及综合性等缺点,本文通过在A型分子筛合成中增添考察"碱度、晶化温度和晶化时间"3个实验变量因素,有目的、有计划、系统地引导学生分析和解决问题,以期达到综合化学实验的目的。

关键词: 综合实验, A型分子筛, 碱度, 晶化温度, 晶化时间

Abstract:

As a typical member of the zeolite family, zeolite A has been mentioned in inorganic chemistry, physical chemistry, and colloid chemistry. However,it often lose its charm in a class with so many students as well as in the ocean of knowledge. In the comprehensive experiment class for college seniors, exploring the effects of the alkalinity, temperature and time of crystallization in synthesizing zeolite has been added to guide the students to analyze and solve problems.

Key words: Comprehensive experiment, Zeolite A, Alkalinity, Crystallization temperature, Crystallization time
