In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and hydrophobic; their odor is usually faint, and may be similar to that of gasoline or lighter fluid. They occur in a diverse range of molecular structures and phases: they can be gases (such as methane Web23 mei 2016 · Most (but not all) hydrocarbons are best incinerated according to this simplified LCA approach (e.g., n -hexane but not toluene). The same applies to diethyl ether. The functionalised solvents with longer production routes are best recycled to retain the energy and value invested into the molecule during its original synthesis (e.g., DMF). Web25 aug. 2009 · This paper aims to provide a review of the analytical extraction techniques for polycyclic aromatic hydrocarbons (PAHs) in soils.
