Solubility of 4-Nitrotoluene,2,6-Dinitrotoluene,2,3-Dinitrotoluene,and 1,3,5-Trinitrobenzene in Pure Water and Seawater

摘要

The solubility of 2,6-dinitrotoluene(2,6-DNT),2,3-dinitrotoluene(2,3-DNT),4-nitrotoluene(NT),and 1,3,5-trinitrobenzene(TNB)was measured in seawater with ionic strength=(0.1662,0.3352,0.5071,and 0.6820)mol·L~(-1)and pure water at temperatures between(277 and 314)K.The pure water solubility values compare well with values reported previously.The solubility in seawater was lower than that in pure water.The average salting-out coefficients for NT,2,6-DNT,2,3-DNT,and TNB were(0.15,0.12,0.13,and 0.09)L·mol~(-1),respectively,which are consistent with measurements for other nitroaromatic compounds.The salting-out coefficients did not show any significant variation with temperature over the range examined.
