Reasons and requirements of constant pressure funnel for preparing cyclohexanoic acid

For the preparation of cyclohexanoic acid, using constant pressure funnel is an ideal preparation method. The constant pressure funnel can keep the pressure stable, thus ensuring the accuracy of experimental conditions. The main reason for using constant pressure funnel to prepare cyclohexanoic acid is that constant pressure funnel can effectively control gas pressure and avoid the influence of gas pressure change on reaction rate. In addition, the constant pressure funnel can continuously add reactants during the reaction to prevent side reactions in some chemical reactions.

Some requirements that should be paid attention to when using constant pressure funnel to prepare cyclohexanoic acid. Firstly, the pressure of the funnel must be strictly controlled to ensure the stability of the reaction conditions for preparing cyclohexanoic acid. Secondly, the constant pressure funnel should be made of materials with high corrosion resistance to avoid the corrosion of the funnel materials by reactants. In addition, the fine adjustment of manual control funnel should be accurate, so please be patient and focused. Finally, some other reagents, such as drying tubes and glass filter instruments, need to be added in the preparation process to avoid the influence of external factors on the experiment.
