摘要

以N-甲基吗啉和对氯苯胺为原料，丙酮为溶剂，制备了N-甲基-N-对胺基苯基吗啉离子液体；利用该离子液体辅助，在水热条件下制备锗酸盐分子筛，考察了晶化温度、离子液体用量、体系水含量及酸度对锗酸盐分子筛制备的影响，对分子筛形貌及晶型进行了表征. 结果表明，酸度与离子液体用量对分子筛晶粒尺寸有影响，温度与体系水含量对分子筛形貌影响显著，体系水含量能改变分子筛晶型结构，所制多数分子筛在1000℃内失重未超过4%.

Abstract

N-methyl-N-amine phenyl morpholine ionic liquid was prepared using N-methyl morpholine and chloro aniline as raw material and acetone as solvent. The germanate molecular sieves were prepared by hydrothermal conditions with the aid of the ionic liquid. Four parameters affecting hydrothermal synthesis of germinate molecular sieves were investigated, including synthesis temperature, dosage of ionic liquid, water content and acidity. The synthesized germinate molecular sieves were characterized. The results showed that synthesis dosage of ionic liquid and acidity have a higher impact on crystal morphology. Temperature and water content are effective on the crystal size. In addition, water content can change the zeolite phases. The weight loss of most molecular sieve is not more than 4% within 1000℃.

Key words： ionic liquid; molecluar sieve; hydrothermal method; XRD; SEM
