Viscosity of potassium carbonate solutions promoted by new amines

Abstract

"The objective of this paper is presenting the experimental results of the viscosity measuring for the aqueous solutions of potassium carbonate with new amines as promoters. In this work, ethylenediamine (EDA) and triethylenetetramine (TETA) were chosen as rate promoter candidates. The viscosity of the ternary aqueous solutions (K2CO3-Amine-H2O) has been measured for a blending 25 wt % potassium carbonate, amine concentrations between 1 to 7 wt % for EDA and 1 to 3 % for TETA, at atmospheric pressure and temperatures from 298 K to 343 K."
