Journal ArticleDOI
Studies on Absorption of Eutectic Mixture. I. A Comparison of the Behavior of Eutectic Mixture of Sulfathiazole and that of Ordinary Sulfathiazole in Man.
Keiji Sekiguchi,Noboru Obi +1 more
TL;DR: In this paper, it was observed that a eutectic mixture of sulfathiazole and urea produces a microcrystalline suspension of the drug in water, which can be used to adjust the therapeutic effect of medical compounds.
Journal ArticleDOI
Studies on Absorption of Eutectic Mixture. II. Absorption of fused Conglomerates of Chloramphenicol and Urea in Rabbits.
TL;DR: High correspondence between dissolution and absorption rate indicates that the absorption of chloramphenicol is largely dependent on the rate of dissolution which is intimately related to the physical state.
Journal ArticleDOI
Studies on the Reaction between Polynitrobenzene Compounds and Active Methylene Groups. VII. On the Colored Substances of the Janovsky and the Zimmermann Reactions
TL;DR: The color-substance C9H9O5N2K (III) was successfully isolated from the Janovsky reaction-mixture of acetone, m-dinitrobenzene (I), and potassium hydroxide as discussed by the authors.
Journal ArticleDOI
Studies on the Reaction between Polynitrobenzene Compounds and Active Methylene Groups. IX. On the Janovsky Complexes derived from Some I-Substituted 2, 4, 6-Trinitrobenzene Derivatives
TL;DR: In this paper, the stability of the Janovsky complexes of 1, 3, 5-trinitrobenzene (TNB), PC and TNA were studied and their large stability constants were noticed.
Journal ArticleDOI
Studies on the Reaction between Polynitrobenzene Compounds and Active Methylene Groups. VIII. On the Janovsky Reaction of Trinitroanisole in Acetone
TL;DR: In this paper, the authors investigated the Janovsky reaction of 2, 4, 6-trinitroanisole (TNA) and acetone in the presence of sodium methoxide and found that the final spectrum having maxima at 443 and 531 mμ in the reaction mixture coincides with the formation of Janovsky complex IVb, were clarified by NMR spectroscopy.
