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℃.
