Abstract: Thiols (mercaptans), alkyl sulfides (dimethyl sulfide and methyl ethyl sulfide), and cyclic sulfides, such as tetrahy- drothiophene, have been widely used in the odorization of natural and liquefied petroleum gas due to the fact that natural gas does not possess an odor. Mercaptans, for example, have proven to be very effective in odorizing be- cause of their low odor threshold and therefore, immedi- ate impact on the olfactory system (Roberts, 1993). Although, gas odorants are characterized as having a low hazard potential regarding health effects, their unique physical chemical properties such as, high flam- mability, require that they be handled safely.
