n: a saturated aliphatic hydrocarbon having the formula CnH2n+2 (e.g., methane, CH4;ethane, C2H6). Heavier paraffin hydrocarbons (i.e., C18H38) form a wax-like substance that is called paraffin. These heavier paraffins often accumulate on the walls of tubing and other production equipment, restricting or stopping the flow of the desirable lighter paraffins.

normal or straight carbon chain alkanes with carbon chain lengths of C18+. The alkanes in this range solidify at temperatures from 80oF to over 200oF. Paraffin is amorphous but may appear to have structure in slow growth examples.
