Abstract A methodology for the oxidation of α-trifluoromethyl alcohols to corresponding trifluoromethyl ketones is presented. catalytic quantity a nitroxide used, and potassium persulfate serves as terminal oxidant. The proves effective aromatic, heteroaromatic, conjugated alcohol substrates. It can be extended nonfluorinated secondary and, in this case, applied range aliphatic alcohols.

In this work, an Fe3O4 catalyst was synthetized in a single step via electrochemical synthesis. The used to evaluate the degradation of Ofloxacin (OFX) using heterogeneous advanced oxidation process with sodium persulfate (PS). PS activation successfully achieved thermal conventional heating directly and subsequently applied for OFX. kinetics were studied under different conditions, such as oxi...

The advanced oxidation process based on persulfate has a broad application prospect in the remediation of organic pollutants. As an effective, low-cost and environmentally friendly material, nano-zero-valent iron (nZVI) can effectively activate (nZVI/PS) to generate strongly oxidizing sulfate radical for removing pollutants environment. In this review, we first clarify activation pathway nZVI a...

Wastewaters from the olive oil industry are a regional environmental problem. Their phenolic content provides inherent toxicity, which reduces treatment potential of conventional biological systems. In this study, Sulfate Radical based Advanced Oxidation Processes (SRbAOPs) compared with advanced oxidation processes (namely Fenton’s peroxidation) as depuration alternative. Synthetic mill wastew...

cis-3-Acetoxy-4-(3-aryloxiran-2-yl)azetidin-2-ones were prepared through a Staudinger [2+2]-cyclocondensation between acetoxyketene and the appropriate epoxyimines in a highly diastereoselective way. Subsequent potassium carbonate-mediated acetate hydrolysis, followed by intramolecular ring closure through epoxide ring opening, afforded stereodefined 3-aryl-4-hydroxy-2-oxa-6-azabicyclo[3.2.0]he...

Total organic carbon (TOC) can reflect the total amount of matter in water. This paper introduces common methods measuring carbon, including high temperature combustion method, potassium persulfate oxidation spectrometry, ozone chemiluminescence supercritical water method and so on. At present, is most widely used for TOC measurement seawater, because its efficiency. sensor needs to be develope...

Methyl tert-butyl ether (MTBE) has been used in many countries as an octaneenhancing replacement for lead, primarily in midand high-grade gasoline. The prevalent use of MTBE has led to its introduction into environment. MTBE is poorly adsorbed, biologically and chemically stable, making it very persistent in the environment. MTBE has been classified as a possible human carcinogen. Many studies ...
