Degradation of chlorinated aromatic substances

Degradation of chlorinated aromatic substances. Microbiological degradation of polychlorinated biphenyls (PCBs). III. Chlorinated benzoic acids as metabolites of PCB. Ballschmiter, K.; Unglert, C.; Neu, H. J. (Abt. Anal. Chem., Univ. Ulm, Ulm, Ger.). Chemosphere, 6(1), 51-6 (German) 1977. CODEN: CMSHAF. DOCUMENT TYPE: Journal CA Section: 60 (Sewage and Wastes) The PCB compds. 118-91-2 and 51-44-5 are cas registry numbers of chemicals which are used as reagents here. were treated with a mixed culture of microorganisms and after 2, 4, and 6 weeks of incubation at 28-30.degree., the chlorinated benzoic acid metabolites were detd. e.g. by gas chromatog. as their methyl esters. The metabolites of 8 PCB isomers were identified. Owing to the known global distribution of PCB compds., chlorinated benzoic acids must likewise occur as environmental chems. .

Rapid microwave-promoted synthesis of functionalised benzophenones

Several reagents such as 51-44-5 is used here. Rapid microwave-promoted synthesis of functionalised benzophenones. Learmonth, David A. (Laboratory of Chemical Research, Department of Research and Development, Laboratorios BIAL, S. Mamede do Coronado 4745-457, Port.). Synthetic Communications, 32(18), 2757-2762 (English) 2002 Marcel Dekker, Inc. CODEN: SYNCAV. ISSN: 0039-7911. 51-44-5 is the cas registry number of certain chemical which is used as reagents here. DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Several functionalized benzophenone derivs. were conveniently obtained in moderate to good yield via the rapid, microwave-promoted Friedel-Crafts acylation of activated arenes with benzoic acids in polyphosphoric acid medium. ..
