Abstract
The heat of reaction of several fatty acid chlorides with ethanolamine s was determined. Mixtures of C-10-C18 fatty acid chlorides, oleyl and stearyl chlorides and ethanolamines (monoethanolamine-MEA, diethanola mine-DEA, triethanolamine-TEA) were used. The influence of the amine t ype, molar ratio and the fatty acid chloride molecular weight on the r eaction heat were studied An adiabatic calorimeter with isothermal man tle was used for the experimental determination of the heat of reactio n. It was noticed that the exothermal heat of reactions decreases in t he following order: TEA > MEA > DEA, but these values increased simult aneously with the molecular weight of the fatty acid chloride and with the excess of the fatty acid chloride.
