The tables of physical properties are the result of an extensive literature search that has been continued as part of the Bureau of Mines study of sulfur compounds in petroleum. This study, carried on cooperatively with American Petroleum Institute research project 48, is concerned with the types of sulfur compounds that have been found in petroleum, namely the thiols (mercaptans), sulfides (thioethers), disulfides, and thiophenes. The tables in this paper include all of these compounds from c14 to cn which are composed only of carbon, hydrogen, and sulfur atoms. The values in these tables are from the literature through 1955. Two other papers include the literature through 1955 for the compounds from c1 through c13 and the literature from 1956 through 1960 for the compounds from c1 to cn.
