Analysis of Diethanolamide Reaction by using FTIR Technique

Abstract

The purpose of this work is to study the amidification reaction for production of diethanolamide from ethyl acetate and diethanolamine by using sulfuric acid catalyst. The amidation, which is the reaction between ethyl acetate and diethanolamine, was held in a glass batch reactor with mole ratio 1:1 using acid catalyst (H₂SO₄) 0.5% (w/w) and 200 rpm stirring. The reaction temperature is 160°C constant, and sampling was performed after every 30 min. The analysis includes Fourier transfer infra-red (FT-IR) to know the structure of amide.
