✦ Synopsis

The determination of sulfur in organic compounds usually involves either the Pregl catalytic combustion method or the Parr Bomb method. In the synthesis of organic compounds containing sulfur an6 particularly when its radioactive isotope is used, a more rapid procedure than the two mentioned above is required so that the course of the reactions can be followed. Since many organic sulfides can be fairly readily oxidized to the sulfoxide (R2SO) and even to the sulfone (R2SO2), it was thought that this property could be used as a basis for their quantitative determination.

Goldstone and Jacobs (Industrial and Engineering Chemistry, Analytical Edition, I6 : 2o6, I944) have recently Shown that trivalent arsenic and antimony could be quantitatively oxidized in acid solution to the pentavalent state using a standard sodium hypochlorite solution (prepared by them from Chlorox) as oxidant and methyl orange as indicator.

Kolthoff and Stenger (ibid., 7: 79, I935) had studied the use and
