STEREOCHEMICAL COURSE OF THE ENZYMATIC AMINATION OF CHLORO- AND BROMO- FUMARIC ACID BY 3-METHYLASPARTATE AMMONIA-LYASE

Enzymatic amination of chloro- and bromo- fumaric acid using 3-methylaspartate ammonia-lyase in the presence of ammonia leads to the formation of 3-chloro- and 3-bromo-aspartic acid respectively; the absolute configuration of each product is (R) at C-2 and (S) at C-3.

Chlorine dioxide catalytic oxidation and online FTIR spectroscopic analysis of simulated o-chlorophenol wastewater

An activated carbon-MnO2 catalyst was prepared and used for chlorine dioxide catalytic oxidation of simulated o-chlorophenol wastewater. The COD removal efficiencies of chemical oxidation and catalytic oxidation are 28.6 and 93.5%, respectively

Metallophthalocyanines linked to organic copolymers as efficient oxidative supported catalysts

The covalent anchoring of metallo(chlorosulfonyl)phthalocyanines 1 onto the acrylic copolymers 2 and 3 has been achieved. When using H2O2 or KHSO5 as oxidant, these supported catalysts are able to oxidize a poorly biodegradable molecule such as 2,4,6-trichlorophenol or a tannin model such as 3,5-di-tert-butylcatechol. The influence of the spacer and the nature of the reaction medium on the catalytic activities have been studied, as well as the recycling of these supported metallophthalocyanine catalysts.
