Webdissolved in the physical solvent. In some cases, however, the hydrocarbon solubility actually increases with temperature [2]. Solvent water content also affects hydrocarbon pickup. The higher the water content, the less the hydrocarbon absorption [3, 4]. This characteristic also aids in separating the solvent from the hydrocarbon [5]. Heptane (and its many isomers) is widely used in laboratories as a non-polar solvent. As a liquid, it is ideal for transport and storage.
