AI Technical Summary

Technical Problem

During the preparation of n-propyl acetate, when adding raw materials or catalysts to the reactor, gas leakage is easily caused, resulting in safety accidents and affecting health.

Method used

A n-propyl acetate preparation reactor is designed to prevent gas leakage, including the reactor body, feed assembly and discharge port. The feeding assembly consists of a feeding chamber, an upper closure cover and a lower closure door. The upper closure cover is equipped with an electric air pump and an expansion balloon. The inflatable balloon is inflated by an electric air pump to discharge the gas in the cavity to ensure that no gas is leaked when raw materials or catalyst are added.

Benefits of technology

It effectively prevents gas leakage in the reactor, improves the safety of n-propyl acetate preparation process, and reduces the risk to staff health.
