9 Αυγ 2020 · Information on the properties of common solvents used in organic chemistry including boiling points, solubility, density, dielectric constants, and flash points.
For several substances, such as water, values are shown for two standard states, (1) and (g). The relation between these is shown in Example 12.7. The standard states in Table A.8 are (g), pure ideal gas at. 1 bar; (l) and (s), the normal state of that substance at 1 bar.
Ligroin is the petroleum fraction consisting mostly of C 7 and C 8 hydrocarbons and boiling in the range 90‒140 °C (194–284 °F). The fraction is also called heavy naphtha. [1][2] Ligroin is used as a laboratory solvent. Products under the name ligroin can have boiling ranges as low as 60‒80 °C and may be called light naphtha. [3]
The estimated BCF of ligroine ranges from 60 to 80(SRC), using log Kows for n-pentane of 3.39 and isohexane of 3.21(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF range suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
Values for relative polarity, eluant strength, threshold limits and vapor pressure have been extracted from: Christian Reichardt, Solvents and Solvent Effects in Organic Chemistry, Wiley-VCH Publishers, 3rd ed., 2003, and the chemidplus site.
