“…LTsami (426) reacted diphenvlamine with mercuric acetate to give a product which exhibited a polarographic wave whose height was proportional to the original concentration of the amine. Kuffner, Sattler-Dornbacher, and Humer (237) analyzed the reineckates of aliphatic amines by titration using silver nitrate solution and dichlorofluorescein as indicator. A report on the recommended specifications for the Van Slyke manometric apparatus has been published (402).…”
