Microdetermination of Sulfate Obtained from Combustion of Organic Compounds

The teaching of microchemistry

“…The students can then be readily taught the limitations and advantages of each of these methods. Among the sulfur methods we mention in passing the industrial titration of SOy" by means of the tetrahydroxyquinone indicator and the technic of using a color filter to determine a difficult endpoint (13).…”

Improved Semimicrodetermination of Sulfur in Organic Materials Peroxide-Carbon Fusion Followed by a Titration Using Tetrahydroxyquinone Indicator

“…(10) Kulikov, I. V., and Panova, S. V., J. Gen. Chem. (U. S. S. R.), 2 (64), 736 (1932). Presented before the Division of Analytical and Micro Chemistry at the 102nd Meeting of the American Chemical Society, Atlantic City, N. J.…”

Microdetermination of Sulfur in Organic Compounds

“…Hallett and Kuipers (2), Sundberg and Royer (6), Alieino (1), and Ogg, Willits, and Cooper (4). All these authors used the catalytic combustion method to destroy organic material and to convert the organically bound sulfur to sulfate, previous to the titration with barium chloride.. A demonstration by Willits and Ogg in their laboratory convinced the present authors of the value of the illuminated titration stand technique, and they decided to adopt the method in this laboratory.…”
