Strong oxidizing agentPotassium permanganate has strong oxidation and is often used as oxidants in the laboratory and industry, being sweet and astringent and is soluble in water with the solution being purple. It will undergo decomposition immediately when coming across ethanol. In acidic medium, it...
摘要: The tertiary amine mentioned in the title is employed as a cheap, stable, non-toxic, and non-cation specific phase-transfer catalyst for various oxidation reactions with potassium permanganate in methylene chloride.关键词: oxidation, dehydrogenation, ozonolysis DOI: 10.1002/chin.198804111 ...
ln case the phenolic hydroxyls were etherified by propylene oxide the copolymerization was going smoothly: The basic grafting conditions of hydroxypropylated SGW were studied. X-ray analysis showed that the copolymerization took place not only within the amorphous region but in the crystalline region ...

In the first method (indirect method), PGH was reacted with a measured excess of standard permanganate in H2SO4 medium, and the residual oxidant was determined by measuring its absorbance at 550 nm. The second method (Direct method) entails treating PGH with permanganate in NaOH medium, ...
In the first two methods potassium permanganate in neutral or basic medium was used. In the other method two stages of oxidation were used: nitric acid followed by potassium permanganate in acidic medium. The latter proved to be more successful.doi:10.1080/00908318608946053...
In acidic medium, the decrease in absorbance at 525.5 nm and in basic medium, the increase in absorbance at 608.5 nm were measured as a function of time. The variables affecting the reactions were carefully investigated and optimised. Kinetic models such as initial rate, rate constant, variable...
