TL;DR: In this paper, the volatile components of violet leaves were extracted with 1,1,2-trichloro-1, 2,2, 2-trifluoroethane as well as hexane and analysed using GC, GC-MS and GC-FTIR.

TL;DR: The results suggest that co-exposure of hexane and toluene could inhibit hexane metabolism and decrease hexane neurotoxicity in both experimental animals and workers.
Abstract: The effects of co-exposure of hexane and toluene were investigated in field surveys and animal experiments. One field survey suggested that increase of hexane content in adhesives might have caused an outbreak of polyneuropathy in a vinyl sandal manufacture in Japan. The animal experiments proved that co-exposure of hexane and toluene decrease hexane neurotoxicity and urinary excretion of hexane metabolites in rats. The results also suggested that toluene might inhibit metabolism of hexane. Another recent field survey indicated that the ratio of urinary 2,5-hexanedione to hexane exposure in the workers co-exposed to hexane and toluene decreased in parallel with in more crease of toluene concentration. The results indicated that urinary excretion of 2,5-hexanedione could be depressed by co-exposure of toluene even in the workers exposed to relatively low concentrations. These above-mentioned results suggest that co-exposure of hexane and toluene could inhibit hexane metabolism and decrease hexane neurotoxicity in both experimental animals and workers. Although metabolism of hexane could be easily modified by toluene or other solvents and might not be a good indicator for hexane exposure in mixed exposure, urinary 2,5-hexanedione might be a good indicator for neurotoxicity of hexane even in mixed exposure.

TL;DR: In this article, the authors measured the excess molar volumes for binary mixtures of butanol (n-C4H9OH) + pentane, hexane, heptane, octane, and carbon tetrachloride (CCl4) at both temperatures 288.15 K and 298.15K.
Abstract: Excess molar volumes, have been measured for binary mixtures of butanol (n-C4H9OH) + pentane (n-C5H12), + hexane (n-C6H14), + heptane (n-C7H16), + octane (n-C8H18), + 2,2,4-trimethylpentane (2,2,4-TMP), and + carbon tetrachloride (CCl4) at 288.15 K and 298.15 K, and refractive indexes, nD, have been measured for these mixtures at 298.15 K. At both temperatures has been found to be positive throughout the entire range of composition for xn-C4H9OH + (1 − x)n-C7H16 and + (1 − x)n-C8H18. At both temperatures 288.15 K and 298.15 K, is positive at low mole fractions of n-C4H9OH and negative at its higher mole fractions in the case of mixtures of n-C4H9OH with n-C5H12, n-C6H14, 2,2,4-TMP, and CCl4. Values of and nD for the various mixtures of n-C4H9OH have been fitted in smoothing equations.
