A method has been developed for the polarographic determination of elemental sulfur present in liquefied petroleum gases in concentrations as low as 0.01 p.p.m. Samples of liquefied petroleum gases are collected in specially fitted stainless steel bombs. After volatilization of the sample, elemental sulfur remaining in the sample bomb is dissolved in a pyridine-methanol-hydrochloric acid solvent and the resulting solution electrolyzed polarographically. ELEMENTAL sulfur in petroleum products presents an important problem in the industry because of the ease with which it is formed and its corrosive nature. In contact with most metals, elemental sulfur reacts to form the metal sulfides.The corrosive action of elemental sulfur on mercury, copper, and silver has been used for some time as a semiquantitative test for sulfur in petroleum products (1,6,9). During recent years more accurate quantitative methods have become increasingly important in the development and evaluation of new refinery processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
