background: potassium permanganate (pp) is a highly corrosive and deadly agent with a reported lethal dose of 10 g in adults. in this report, successful treatment of a patient poisoned with three times the lethal dose of pp is presented, and effective and early approach to such emergency toxicologic condition is discussed. case presentation:a 24-year-old woman presented to emergency room of our...

Applications of hemp fibers, as a promising natural material in the textile field, mostly require improved fiber properties. In this paper, oxidation fibers with potassium permanganate was applied to reduce amount non-cellulosic substances and moisture sorption; introduce functional groups increase capillarity; make finer, softer suitable for application sport wears. The changes sorption proper...

In an evaluation of procedures explored to circumvent some of the problems of osmium tetroxide-fixation and methacrylate embedding of plant materials, excised segments of root tips of Zea mays were fixed for electron microscopy in potassium permanganate in the following treatment variations: unbuffered and veronal-acetate buffered solutions of 0.6, 2.0, and 5.0 per cent KMnO(4) at pH 5.0, 6.0, ...

This paper describes a procedure for the determination of psilocin and psilocybin in mushroom extracts using high-performance liquid chromatography with postcolumn chemiluminescence detection. A number of extraction methods for psilocin and psilocybin in hallucinogenic mushrooms were investigated, with a simple methanolic extraction being found to be most effective. Psilocin and psilocybin were...

. l-C14_propene~1 has been prepared. The migration of the double bond under a variety of experimental conditions in the preparation of propene has been investigated. 'rhe mechanism of the permanganate oxidation of the labelled propene has been examined; it has been found to proceed by several paths, the relative importance of which depends upon the experimental conditions .. especia lly the pH....

By oxidizing alpha tocopherol with chromic anhydride in acetic acid solution, a lactone C21H4002 was obtained. The origin of such a lactone is easily explicable on the theory that alpha tocopherol contains a chromane ring; if alpha tocopherol contained a coumarane ring, a beta hydroxy acid would be expected. Karrer and his co-workers,2 by treating pseudo cumo hydroquinone with phytyl bromide, o...
