Kinetic Studies of Some Free Radical Reactions
Kinetic and mechanistic studies on some characteristic freeradica1 reactions are reviewed briefly. The unimolecular rearrangements: RCMe2CH ÷ Me2CCH2R, fall into two classes. Class 1: R = R'C(O)O for which the 1,2—migration occurs via a 5—eenter cyclic transition state with considerable charge separation, [R'C02 Me2CCH2]*. Class 2: R = H2C=CH, Me3CC=0, C6H5, Me3CCsC, and CsN, for which migratio...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولFree radicals in carcinogenesis.
It has become clear since the workshop that free radicals are implicated not only in the promotion phase of carcinogenesis but during initiation as well. Since the workshop, however, despite intriguing trapping studies with Superoxide disimilase. catalase, and Cu-DIPS [copper(II)(3,5-diisopropylsalicylate)2] and generation of OJ using xanthine oxidase, little substantive evidence has been obtai...

متن کاملRemediation of 4-nonylphenol in aqueous solution by using free radicals generated by the oxidative reactions
INTRODUCTION This study relates to use of zerovalent iron to generate hydroxyl free radicals and undergo subsequent oxidation to destroy 4-nonylphenol (NP) by mild process in aqueous solution and activation of oxygen gas (O2) at room temperature. This technology is based on a novel oxidative mechanism mediated by zerovalent iron rather than commonly used reduction mechanism. MATERIALS AND MET...
