1. The acute hepatotoxic action of dimethylnitrosamine was investigated with homogenates and mitochondrial preparations from the livers of rats injected with 100 mg./kg. body weight at various times between 8 and 24 hr. before killing. 2. Aerobic oxidation of pyruvate, octanoate, L-malate, citrate, L-glutamate, a-oxoglutarate and ,-hydroxybutyrate progressively decreased after the twelfth hour ...

A unique Taylor-vortex membrane reactor (TVMR) design for continuous gas-liquid reactions is presented in this work. The consists of a cylindrical rotor inside stationary concentric vessel, and flexible system equispaced baffle rings surrounding the rotor. This restricts annular cross section to small gap between baffles rotor, divides annulus into 18 mixing zones. support 6 m long PFA tubular ...

Nanodroplets of sulfur-stabilised copper nanoparticles effectively catalyse the aerobic oxidation amines to imines under ambient conditions.

The first example of a homogeneous silver(I)-catalyzed aerobic oxidation of aldehydes in water is reported. More than 50 examples of different aliphatic and aromatic aldehydes, including natural products, were tested, and all of them successfully underwent aerobic oxidation to give the corresponding carboxylic acids in extremely high yields. The reaction conditions are very mild and greener, re...

Introduction Aerobic catalytic oxidation is much more environmentally friendly than oxidation using stoichiometric oxidants. The Pd(OAc)2/pyridine system is active for the catalytic oxidation of primary and secondary alcohols to aldehydes and ketones, which are valuable for fine chemicals synthesis. Pyridine stabilizes the monomeric Pd complex and promotes its aerobic reoxidation to Pd prior to...

The oxidation of hypersensitive radical probes by chloroperoxidase from Caldariomyces fumago (CPO) was studied in an attempt to "time" a putative radical intermediate. Oxidation of (trans-2-phenylcyclopropyl)methane, previously studied by Zaks and Dodds [Zaks, A., and Dodds, D. R. (1995) J. Am. Chem. Soc. 115, 10419-10424] was reinvestigated. Unrearranged oxidation products were found as previo...
