Comparison of heptane extractables and xylene solubles methods showed differences in the structure and molecular weight of heptane and xylene soluble fractions and heptane and xylene insoluble fractions, respectively.doi:10.1002/macp.1994.021950507Arja Lehtinen...
Generally, hydrocarbon derivatives of low molecular weight, e.g., methane, ethane, and propane, are gases; those of intermediate molecular weight, e.g., hexane, heptane, and octane, are liquids; and those of high molecular weight, e.g., eicosane (C20H42) and polyethylene, are solids. ...
The asphaltenes were dissolved in toluene and then partially precipitated at specified ratios of heptane/toluene to generate sets of light (soluble) and heavy (insoluble) cuts. The molecular weight and density were measured for each cut. The asphaltenes were found to include both associating and ...
What is the molecular weight of methane? What is the structural formula of 10 isomers of heptane? What is molecular mass? What is the IUPAC name for this alkane: (CH_3)_3CCH(CH_3)CH_2CH_3? What is the emperical formula of toluene?
