Publisher SummaryThis chapter provides the basic synthesis paths routes for the manufacture of dichlorprop, with a listing of the main raw materials and intermediates used in the synthesis of dichlorprop. Dichlorprop is commercially known as Cornox and it belongs to the phenoxy carboxylic acid g...

An aerobic degradation study was conducted to estimate possible effects of elevated ozone concentration in air on the behaviour of dichlorprop. An average ozone concentration of 80 nL L−1 was chosen, which often occurs close to congested areas during late spring and summer. A control soil and an...

The enantioselective toxic mechanisms of chiral herbicides in photosynthetic organisms are closely related to the production of reactive oxygen species (ROS) production, however, there are few reports on how the enantioselective production of ROS can be triggered. In suboptimal conditions, photo...

In order to investigate aerobic degradation potential for the herbicides bentazone, mecoprop and dichlorprop, anaerobic groundwater samples from two monitoring and three drinking water wells near a drinking water abstraction field in Nybølle, Denmark, were screened for their degradation potentia...

This study focused on the synthesis and subsequent characterization of a homologous series of herbicidal ionic liquids (HILs) that incorporate a 2-(2,4-dichlorophenoxy)propionate (dichlorprop) anion and 1-alkyl-1-methylpiperidinium cation with a varied alkyl length from ethyl to octadecyl. Novel...

The UV photolysis of 2′-chloro-4-R-benzanilides in acetonitrile solution under nitrogen atmosphere leads to the formation of intramolecular photocyclization products (9-R-phenanthridin-6(5)-one, 20–30%), along with the minor photoreduction, photo-Fries, and intramolecular photosubstitution pro...

The mitigation of carbon emissions is an imminent and extremely relevant issue. In addition to carbon dioxide (CO2), methane (CH4) also contributes significantly to climate change. Dry reforming of methane (DRM) is a promising alternative to mitigate this gas, generating syngas, an important pre...

Constructed wetlands are an environmentally friendly and economically efficient sewage treatment technology, with fillers playing an important role in treatment processes. However, traditional wetland fillers (e.g. zeolite) are known to be imperfect because of their low adsorption capacity. In t...

Sodium ion capacitors (SICs) are increasingly being focused, due to the feature of high energy/power densities derived from the integrated energy storage mechanisms, as well as the ubiquitous sodium sources. Practical anodes with exceptional rate capability can circumvent the kinetic mismatch wi...

Titanate-based materials are attractive inorganic adsorbents for wastewater treatment. In this study, hierarchical hollow sodium titanate microspheres (HHSTMs) were successfully synthesized via a template-assisted method. Silica microspheres were selected as hard templates, with a uniformly smoo...

To obtain more efficient photocatalyst for photocatalytic reduction of CO2 with H2O and figure out the reason for nonstoichiometric O2 evolution, silver-loaded sodium titanate photocatalysts were further studied in the improved reaction conditions. After preliminary tests for two kinds of sodium...

Optical characteristics of a doped material depend on the site wherein the dopant resides. In mixed A-site perovskites, the dopant has several possibilities. This, in turn, correlates with the emission spectrum of the doped material. Here we choose Eu3+ as the dopant since it is a well-known and...

Sodium titanate nanopowder (nominal formula Na1.5H0.5Ti3O7) was directly synthesized using a continuous hydrothermal flow synthesis process using a relatively low base concentration (4 M NaOH) in process. The as-made titanate nanomaterials were characterised using powder X-ray diffraction, X-ray...

An amorphous sodium titanate (ST) nano-particle was prepared via the facile hydrolytic process with the addition of sodium hydroxide and firstly used for ammonia nitrogen (NH3-N) removal from wastewater. ST exhibited satisfactory adsorption efficiency for NH3-N simulative wastewater (20 mg·L−1)...

In this paper, nanotubes and nanoribbons of sodium titanate structures were synthesized via hydrothermal methods in alkaline solution. CdS decorated titanate nanotubes and nanoribbons were therefore constructed for exploring the performance of hydrogen evolution and synergistic effect of CdS bas...

Thermal rearrangement of 1,3-dichloro-6-ethoxycarbonyl-2-thiabicyclo[3, 1, 0]hex-3-ene does not follow the anticipated course, but leads instead to ethyl-2,4-dichloro-5-hydroxy-6-methylbenzoate, whose structure has been confirmed by an X-ray crystal structure determination.

Tropinone reductases (TRs) are small proteins belonging to the SDR (short chain dehydrogenase/reductase) family of enzymes. TR-I and TR-II catalyze the conversion of tropinone into tropane alcohols (tropine and pseudotropine, respectively). The steps are intermediary enroute to biosynthesis of t...

Tropine-type chiral ionic liquid with proline anion was immobilized on silica gel by chemical modification method for the first time, which was proved by elemental, infrared spectrum and thermogravimetric analysis. Secondly, the performance of this kind of ionic liquid-modified silica gel was in...

Phase diagrams for the binary systems ethanol or water + tropine-type ionic liquids including N-benzyl-tropine hexafluorophosphate, N-(3-methoxybenzyl)-tropine hexafluorophosphate, N-(4-nitrobenzyl)-tropine hexafluorophosphate and related ternary systems (ethanol + water + ionic liquid) were mea...

Brugmansia arborea is a woody plant species that produces tropane alkaloids (TAs). The gene encoding tropine-forming reductase or tropinone reductase I (BaTRI) in this plant species was functionally characterised. The full-length cDNA of BaTRI encoded a 272-amino-acid polypeptide that was highly...
