The estimation of sulphur compounds in crude and refined benzoles. Part II

Abstract

Based on the experiments described in Part I, methods of analysis of sulphur compounds that have been found successful are described in detail, followed by a scheme of analysis for a complete examination of the sulphur compounds in a crude or refined benzole. For the sake of convenience, the methods of analysis are given in the order in which they appear in the complete scheme.

Colorimetric Methods for Field Measurement of Sulfide Odorants

“…A number of references were also found from a literature search (2,3,(5)(6)(7)(8)10,11,(13)(14)(15)(16)(18)(19)(20)(21)(22)(23)(24)(25)(26)29,30,(32)(33)(34)44,46,47,49,(51)(52)(53)(54)(56)(57)(58)(62)(63)(64)(65). All these reactions were identified as potentially worthwhile and were examined in a t least abstract form to determine if the general criteria for the test reaction were met a t least in part.…”

Analysis of Voltile Organic Sulfur Compounds by Gas Partition Chromatography

“…Analytical methods for the quanti-_t\_ tative determination of hydrogen sulfide, mercaptans, and alkyl sulfides and disulfides in the presence of each other are of considerable importance in industrial laboratories and in fundamental investigations. Because of similarities in chemical behavior of these compounds, chemical procedures (1)(2)(3)(4)(5)(6) are usually difficult and the results may be unreliable. The success achieved by gas chromatography as an analytical tool has suggested the application of this technique, based on physical rather than chemical differences, to the analysis of sulfur compounds.…”
