Data 2009 2009-03-11 Physicochemical Properties of Aqueous Solutions of 2-Amino-2-hydroxymethyl-1,3-propanediol The density and viscosity of aqueous solutions of 2-amino-2-hydroxymethyl-1,3-propanediol (AHPD) as well as the Henry s law constants and diffusivity of N2O in these solutions were measured over the temperature range from (298 to 323) K at atmospheric pressure. The mass fractions of AHPD used were (2.17 to 21.7) %. The N2O analogy was used to estimate the Henry s law constants and diffusivity of CO2 in aqueous AHPD solutions. The experimental density, viscosity, Henry s law constants, and diffusivity data are correlated as a function of temperature and concentration of amine and compared with the available data in the literature. 10.1021/je800460a 54 444-447 1 tris(hydroxymethyl)methanamine C4H11NO3 1 Commercial source 1 99.8 3 Stated by supplier 2 None used 2 water H2O 1 Commercial source 1 De-gassed by boiling or ultrasonically 1 99.8 3 Estimated by the compiler 3 nitrous oxide N2O 1 Commercial source 1 99.9 3 Stated by supplier 4 carbon dioxide CO2 1 Commercial source 1 99.9 3 Stated by supplier 1 1 2 1 Principal objective of the work RDC TRC 3/11/2009 1 Mass density, kg/m3 Pycnometric method Liquid Direct value, X 1 Author Liquid Pressure, kPa 101 3 1 Mass fraction 1 Liquid 2 Temperature, K 1 Author 1 .0217 3 2 298 3 1 1001.3 5 1 .035 1 .051 3 2 298 3 1 1009 5 1 .035 1 .103 4 2 298 3 1 1021.6 5 1 .035 1 .158 4 2 298 3 1 1033.6 5 1 .035 1 .217 4 2 298 3 1 1046.5 5 1 .035 1 .0217 3 2 303 3 1 999.6 4 1 .035 1 .051 3 2 303 3 1 1007.4 5 1 .035 1 .103 4 2 303 3 1 1019.2 5 1 .035 1 .158 4 2 303 3 1 1031.8 5 1 .035 1 .217 4 2 303 3 1 1044.2 5 1 .035 1 .0217 3 2 313 3 1 994.9 4 1 .035 1 .051 3 2 313 3 1 1002.8 5 1 .035 1 .103 4 2 313 3 1 1014.6 5 1 .035 1 .158 4 2 313 3 1 1026.8 5 1 .035 1 .217 4 2 313 3 1 1038.9 5 1 .035 1 .0217 3 2 323 3 1 988.1 4 1 .035 1 .051 3 2 323 3 1 996 4 1 .035 1 .103 4 2 323 3 1 1008.2 5 1 .035 1 .158 4 2 323 3 1 1019.9 5 1 .035 1 .217 4 2 323 3 1 1032.7 5 1 .035 1 1 2 1 Principal objective of the work RDC TRC 3/11/2009 1 Viscosity, Pa*s Capillary tube (Ostwald; Ubbelohde) method Liquid Direct value, X 1 Author Liquid Pressure, kPa 101 3 1 Mass fraction 1 Liquid 2 Temperature, K 1 Author 1 .0217 3 2 298 3 1 .000913 3 1 .00000913 1 .051 3 2 298 3 1 .000995 3 1 .00000995 1 .103 4 2 298 3 1 .001148 4 1 .00001148 1 .158 4 2 298 3 1 .001353 4 1 .00001353 1 .217 4 2 298 3 1 .001605 4 1 .00001605 1 .0217 3 2 303 3 1 .000874 3 1 .00000874 1 .051 3 2 303 3 1 .00094 3 1 .0000094 1 .103 4 2 303 3 1 .001059 4 1 .00001059 1 .158 4 2 303 3 1 .001223 4 1 .00001223 1 .217 4 2 303 3 1 .001449 4 1 .00001449 1 .0217 3 2 313 3 1 .000733 3 1 .00000733 1 .051 3 2 313 3 1 .000799 3 1 .00000799 1 .103 4 2 313 3 1 .000884 3 1 .00000884 1 .158 4 2 313 3 1 .001008 4 1 .00001008 1 .217 4 2 313 3 1 .001172 4 1 .00001172 1 .0217 3 2 323 3 1 .0006 3 1 .000006 1 .051 3 2 323 3 1 .00065 3 1 .0000065 1 .103 4 2 323 3 1 .000711 3 1 .00000711 1 .158 4 2 323 3 1 .000808 3 1 .00000808 1 .217 4 2 323 3 1 .00093 3 1 .0000093 1 1 2 1 3 1 Principal objective of the work RDC TRC 3/11/2009 1 Henry's Law constant (amount concentration scale), kPa*dm3/mol phase equilibration at constant pressure 3 Liquid Direct value, X 1 2 1 Author Liquid Gas Amount concentration (molarity), mol/dm3 3 Liquid 0 0 1 Solvent: Mass fraction 1 Liquid 1 2 2 Temperature, K 1 .0217 3 2 298 3 1 4183 4 1 62.745 1 .051 3 2 298 3 1 4225 4 1 63.375 1 .103 4 2 298 3 1 4324 4 1 64.86 1 .158 4 2 298 3 1 4473 4 1 67.095 1 .217 4 2 298 3 1 4647 4 1 69.705 1 .0217 3 2 303 3 1 4672 4 1 70.08 1 .051 3 2 303 3 1 4730 4 1 70.95 1 .103 4 2 303 3 1 4851 4 1 72.765 1 .158 4 2 303 3 1 5048 4 1 75.72 1 .217 4 2 303 3 1 5263 4 1 78.945 1 .0217 3 2 313 3 1 6126 4 1 91.89 1 .051 3 2 313 3 1 6230 4 1 93.45 1 .103 4 2 313 3 1 6440 4 1 96.6 1 .158 4 2 313 3 1 6672 4 1 100.08 1 .217 4 2 313 3 1 6791 4 1 101.865 1 .0217 3 2 323 3 1 7784 4 1 116.76 1 .051 3 2 323 3 1 7950 4 1 119.25 1 .103 4 2 323 3 1 8123 4 1 121.845 1 .158 4 2 323 3 1 8301 4 1 124.515 1 .217 4 2 323 3 1 8489 4 1 127.335 1 1 2 1 3 1 Principal objective of the work RDC TRC 3/11/2009 1 Binary diffusion coefficient, m2/s Open capillary Liquid Direct value, X 1 Author Liquid Pressure, kPa 100 3 Mole fraction 3 Liquid 0 0 1 Solvent: Volume fraction 1 Liquid 1 2 2 Temperature, K 1 .0217 3 2 298 3 1 0.00000000155 3 1 .000000000031 1 .051 3 2 298 3 1 0.00000000134 3 1 .0000000000268 1 .103 4 2 298 3 1 0.00000000119 3 1 .0000000000238 1 .158 4 2 298 3 1 0.00000000106 3 1 .0000000000212 1 .217 4 2 298 3 1 0.00000000095 2 1 .000000000019 1 .0217 3 2 303 3 1 0.00000000175 3 1 .000000000035 1 .051 3 2 303 3 1 0.0000000016 3 1 .000000000032 1 .103 4 2 303 3 1 0.00000000138 3 1 .0000000000276 1 .158 4 2 303 3 1 0.00000000127 3 1 .0000000000254 1 .217 4 2 303 3 1 0.0000000012 3 1 .000000000024 1 .0217 3 2 313 3 1 0.00000000222 3 1 .0000000000444 1 .051 3 2 313 3 1 0.00000000212 3 1 .0000000000424 1 .103 4 2 313 3 1 0.00000000189 3 1 .0000000000378 1 .158 4 2 313 3 1 0.00000000176 3 1 .0000000000352 1 .217 4 2 313 3 1 0.00000000169 3 1 .0000000000338 1 .0217 3 2 323 3 1 0.0000000027 3 1 .000000000054 1 .051 3 2 323 3 1 0.00000000263 3 1 .0000000000526 1 .103 4 2 323 3 1 0.00000000234 3 1 .0000000000468 1 .158 4 2 323 3 1 0.00000000225 3 1 .000000000045 1 .217 4 2 323 3 1 0.00000000222 3 1 .0000000000444
