New Synthesis of Polyaniline using a Peroxides Enzyme
A new method for the synthesis of water soluble Polyaniline (PANi) using Hemin Chloride (H.C) in the presence of hydrogen peroxide (H.P) is presented. Hemin chloride is an effective catalyst for the oxidative polymerization of aniline in the presence of hydrogen peroxide at room temperature. The UV- Vis absorption spectra of the product show a distinct absorption peak at 430 nm in pH 4.0 b...
متن کاملDispiro-1,2,4,5-tetraoxanes: a new class of antimalarial peroxides.
Dispiro-1,2,4,5-tetraoxanes 2-4 were synthesized as potential peroxide antimalarial drugs. They had curative activity against Plasmodium berghei in vivo at single doses of 320 and 640 mg/kg which confirms earlier unpublished data. Moreover, artemisinin (1) and 4 had equivalent ED50's against P. berghei in vivo in the multiple-dose Thompson test; neither showed any evidence of acute toxicity at ...

متن کاملThe quest for beryllium peroxides.
There is no experimental proof documented in the literature for the existence of any beryllium peroxide compound. All recent pertinent preparative attempts described in this work, using a range of beryllium salts with various peroxides as reagents under mild conditions, were equally unsuccessful. (1)H and (9)Be NMR investigations of aqueous solutions containing beryllium salts and hydrogen pero...
متن کاملPeroxides and Peroxide Forming Compounds
Inorganic and organic peroxides, because of their exceptional reactivity and oxidative potential are widely used in research laboratories. This review is intended to serve as a guide to the hazards and safety issues associated with the laboratory use, handling, and storage of inorganic and organic peroxy-compounds and peroxide-forming compounds. The relatively weak oxygen-oxygen linkage (bond-d...
