| Abstract: | The viscosities and densities of glycinc and DL-alanine in 1mol·kg￣(-1) sodiumcarbnate aqueous solutions were mcasured at 288.15～328.15K with the high precise viscometer and thesingle stem pycnometer.The viscosity B coefficients and the limiting partial inolar volumes were calcu- lated.The equation was related with the least-squares method between the B coefficients and tempera-ture. The influence on the structure of 1mol·kg￣(-1) Na_2CO_3 was discussed and the flow activationparameters of two amino acids in 1mol·kg￣(-1) Na_2CO_3 aqueous solutions were obtained. |
