1. The rate of the saponification of iodoacetic acid in sodium hydroxide and alkaline buffer solutions yielding glycollic acid was measured by means of Heyrovský's polarographic method. 2. From the bimolecular velocity constants, increasing with the ionic strength of the solution, the Brönsted factor, F, which characterizes the primary salt effect, was calculated. 3. In the borate buffer soluti...

In the February issue of the Indian Medical Gazette, 1889, S. Coull Mackenzie, Police Surgeon of Calcutta, published an account of eight cases of saponification observed by him during his nine years of medico-legal work in that city. In the April issue of the same journal for 1897 Dr. George H. F. Nutall published a paper under the title " Has adipocere been observed in India?" in which he poin...

When vitamin D2 was saponified with addition of BHT in an alkaline solution, the low recoveries were observed. These were confirmed to be due to the oxidation of vitamin D2 by 2, 6-di-tert-butyl-4-methyl-4-hydroperoxy-2, 5 -cyclohexadiene-1-one formed from BHT during alkali saponification. The de composition of vitamin D2 was protected by the addition of sufficient quantities of sodium ascorbat...

Wheat straw-g-polyacrylonitrile (PAN), containing 40% PAN, was saponified with sodium hydroxide and isolated under three sets ofsaponification and work-up conditions. Each reaction mixture was separated into a water-soluble and a water-insoluble fraction, which were individually analyzed for percentages (by weight) of synthetic polymer (saponified PAN), cellulose, hemicellulose, and lignin. Wat...
