Abstract:

This experiment combines the principles and basic operations of physical chemistry and organic chemistry, in which the Brønsted acidic ionic liquid is used as the catalyst for the preparation of n-butylacetate for learning the principles of chemical kinetics, the kinetic equations and related calculations. The results show that the assumption of kinetic equations is consistent with the experimental results. The experiment reflects the results of the recent scientific research with easy operability, which will motivate the students and improving their learning ability and practical ability. It is worthy of recommendation as an experiment in the physicochemical comprehensive laboratory.
