Abstract In a recent article on the “Iodometric Method of Determination of Free Sulfur” by Bolotnikov and Gurova (J. Rubber Ind. U. S. S. R., 10, 61 (1933); Rubber Chem. and Technology, 8, 87 (1935)), the authors described a rapid method for determining free sulfur in rubber without a preliminary extraction.

Abstract 1. The rapid method of determination of total sulfur and ash by ignition of rubber in a current of oxygen is not less accurate than the method of Henriques. 2. The proposed method can be used with all kinds of rubber mixtures except those containing litharge. 3. In the analysis of mixtures containing barytes, all sulfur except that contained in barytes is determined. 4. The method is particularly useful in the determination of sulfur and ash in Resinites (Thiokol), and the sulfate can be determined by the volumetric method.

Free Sulfur

Abstract The determination of free sulfur is probably the analytical process most frequently carried out in the chemical laboratory of a rubber factory, and it would be even more often used, could it be more quickly performed. For the oxidation of the sulfur contained in the acetone extract from rubber, Mackay (J. Soc. Chem. Ind., 49, 401-3T (1930)) has described a rapid method which has been used in these laboratories for several years with complete success, but the sulfate produced has to be determined gravimetrically and the process is still too slow for use in factory control work. The acetone extraction of the rubber samples can usually be carried out at night on a bath with automatic time control, and if a rapid method for the determination of sulfur in the extract were available, the results of the analysis could be ready early next day. From a review of the literature the volumetric determination of sulfate by rhodizonate (Strebinger and von Zombory, Z. anal. Chem., 79, 1 (1929)) appeared to be promising, and on trial has given satisfactory results.
