Résumé

In this work new measurements of electrical conductivity (µS.cm-1) and pH of n-propanethiol and n-butanethiol in N-methyldiethanolamine (MDEA) + piperazine aqueous solution at 306 K and atmospheric pressure. The experiments were performed at three 2.5 ml, 3.0 ml and 5.0 ml volumes of n-propanethiol and n-butanethiol in 45 wt % and 18 wt % MDEA aqueous solutions. The piperazine concentration has been kept constant by 4 wt % in all the experiments. The changes in electrical conductivity (EC) with time have been related to the change in concentration of ionic species and change of pH has been related to the acid-base neutralization reaction.
