Flue gas produced by biomass fuel combustion contains various chlorine-containing substances and is an important factor causing boiler corrosion. The corrosion processes of chlorine, hydrogen chloride water on iron covered with intact/damaged oxide film were investigated under the high temperature 1300 K through reactive molecular dynamics simulation. results show that diffusion oxygen chlorine...

a convenient, one-pot method for the synthesis of diazonium salt has been developed by the sequential diazotization of aromatic amines with nano2, polymer- supported periodic acid (ppia) and 2-naphthole under solvent-free conditions at room temperature. by using this method, several types of aromatic amine, containing electron-withdrawing and electron-donating groups, were rapidly converted to ...

In a heterogeneous electrolyte system of a strongly basic anion exchanger and solutions of NaBF4 or NaClC>4 we established the influence of the nature and concentration of the eluent in chromatographic experiments on chlorine isotope separation. Results show that when the electrolyte concentration is increased the degree of isotope separation decreases. With NaBF4 the separation factor is great...

Nucleophilic substitutions of the reactive chlorine atoms in either cyanuric or phosphonitrilic chloride by the bridging 4,4’-bipyridine, 1,4-phenylenediamine or benzidine units lead to the formation of two(2-D) or threedimensional (3-D) covalent networks, according to the spatial arrangement of the chlorine atoms in each particular triazine core. 1-2 The materials are electrochemically active ...

Hydrolytic lignin is a large-tonnage waste product of ethyl alcohol production and renewable resource. The structure characterized by the presence large number hydroxyl groups, which provides value as raw material for synthesis in polymer chemistry. But due to their low chemical stability dilute alkalis, acids solvents, lignins are little use wide practical use. introduction additional function...

We investigate the effect of various spherical nanoparticles on chain dimensions in polymer melts for high nanoparticle loading which is larger than the percolation threshold, using molecular dynamics simulations. We show that polymer chains are unperturbed by the presence of repulsive nanoparticles. In contrast polymer chains can be perturbed by the presence of attractive nanoparticles when th...

This project has the objective to investigate the economic and technical perspectives for the replacement of woody biomass with non-woody biomass in a biomass gasification process. Non-woody biomass fuels like straw, manure and sludge are cheap fuels with an increased chlorine, sulphur and ash content. A representative biomass composition for non-woody biomass is 13 wt% ash, 0.3 wt% chlorine an...

BACKGROUND AND OBJECTIVE Many clinicians will not treat patients presenting with bisphosphonate-related osteonecrosis of the jaw following long-term use of bisphosphonates because of the lack of predictable outcomes. MATERICAL AND METHODS: The patient presented with pain from a nonhealing lesion in the posterior maxilla following extraction of the maxillary right third molar. The lesion had n...

The organoindium subhalide [R(Cl)In-In(Cl)R]2 [R = C(SiMe3)3] 1 reacts with Na2[Fe2(CO)8] to form an iron-indium coordination compound which was isolated as the sodium choride adduct [Na(THF)4][Fe2(CO)6(μ-CO)(μ-InR)2Cl] 2. The iron atoms of 2 are bridged by a CO ligand and two InR groups, the indium atoms of which are further connected by the μ2-bridging chlorine atom. Four THF molecules and tw...
