Refining of Low Temperature Cresol No. 1

THE ANODIC OXIDATION OF BASES IN THE SOLVENT no-CRESOL

Acid-base titrations can be carried out successfully in the solvent ??Icresol’. This is important for the determination of the acid or base content of some polymers for which ~cresol is a good solvent. The study of acid-base coulometry in nr-cresol was started because of the several advantages offered by coulometry: greater sensitivity, no problems with unstable titrants, and no need for standa...

Low-Temperature Remediation of NO Catalyzed by Interleaved CuO Nanoplates

A copper(II)-oxide-based exhaust catalyst exhibits better activity than Pt- and Rh-nanoparticle catalysts in NO remediation at 175 °C. Following theoretical design, the CuO catalyst is rationally prepared; CuO nanoplates bearing a maximized amount of the active {001} facet are arranged in interleaved layers. A field test using a commercial gasoline engine demonstrates the ability of the catalys...

Low-temperature redetermination of benzofurazan 1-oxide

In the six-membered ring of the low-temperature crystal structure of benzofurazan 1-oxide, C(6)H(4)N(2)O(2), the two C atoms adjacent to the N atoms are linked by a delocalized aromatic bond [1.402 (2) Å]; each is connected to its neighbour by a longer, more localized, bond [1.420 (2), 1.430 (2) Å]. However, the next two bonds in the ring approximate double bonds [1.357 (2), 1.366 (2) Å]. As su...

Formation of highly oxygenated low-volatility products from cresol oxidation

Hydroxyl radical (OH) oxidation of toluene produces ring-retaining products: cresol and benzaldehyde, and ring-opening products: bicyclic intermediate compounds and epoxides. Here, firstand later-generation OH oxidation products from cresol and benzaldehyde are identified in laboratory chamber experiments. For benzaldehyde, first-generation ring-retaining products are identified, but later-gene...
