Microcalorimetric Study of the Oscillation System for the Extraction of Acetic Acid with Primary Amine with Primary Amine
Abstract:
The power－time curves of the extraction oscillation system were determined at different temperatures and acidities,for the extraction of acetic acid with primary amine N1923 in chloroform,using the perfusion/titration microcalorimetric method.The apparent activation energy were calculated from the induction period (tin),the first oscillation period (tp.1)and the second oscillation period (tp.2).The regularity of the oscillation system was discussed.
The following equations were obtained
tin=30.857＋1 001.43 cHAc, tp.1=101.714＋252.86 cHAc, tp.2=75.429＋175.71 cHAc .
