Aniline decompression distillation experiment is a common experimental method in chemical experiments, and aniline is purified and separated by decompression distillation. In the aniline vacuum distillation experiment, need to pay attention to the following matters:

1. preparation of experimental equipment: before the vacuum distillation experiment, to ensure that the experimental equipment intact, especially the vacuum distillation device and vacuum pump and other equipment need to undergo strict inspection and maintenance, to ensure the safety and smooth progress of the experiment.
2. Control of experimental conditions: When conducting aniline decompression distillation experiments, it is necessary to strictly control the experimental conditions, including temperature, pressure and other parameters, to ensure the accuracy and repeatability of the experiment, and also pay attention to the safety during the experiment. problem.
3. Specification of operation process: When conducting aniline decompression distillation experiment, it is necessary to follow the standard operation process to avoid operation errors or safety accidents, especially when dealing with toxic substances.
4. Record and analysis of experimental data: When conducting aniline decompression distillation experiments, the experimental data should be recorded in time and reasonable data analysis should be carried out in order to draw accurate experimental conclusions.
5. Treatment of experimental waste: After the experiment, all kinds of experimental waste should be properly handled to ensure the cleanliness and tidiness of the experimental site.

Aniline vacuum distillation experiment is a common but need to attach great importance to the chemical experiment, the experimental personnel before the experiment to make full preparation and safety measures to ensure the smooth progress of the experiment and the accuracy of the experimental results.
