Herein, the ability of this technique to be used for on-time monitoring of a model chemical reaction is demonstrated. Every chemical reaction is characterized by specific kinetic profile, especially when a reversible reaction as esterification has to be realized. The selection of an appropriate, easy to be applied tracking technique is an important moment in the industry. N-butyl acetate can be obtained by the esterification of n-butan-1-ol and acetic acid. The main purpose of the presented work is to study the kinetics of the model reaction of n-butyl acetate synthesis showing the ability of FT-IR technique in solution to be used. Process of on-time monitoring can help to study the external factors which influence on the both right and reversed reaction in order to obtain the best yield of aimed product. The obtained results showed that FT-IR technique could be used as an easy to be applied for on-time monitoring of esterification reaction technique and the reaction reaches equilibrium in the 90th minute. Otherwise, a yield of 100 % is observed after one hour and half since the beginning of the reactionenArticle
