Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 17927-65-0, is researched, SMILESS is O=S(O)(O)=O.O=S(O)(O)=O.O=S(O)(O)=O.[H]O[H].[Al].[Al], Molecular Al2H8O13S3Journal, Cement and Concrete Research called Solid solution between Al-ettringite and Fe-ettringite (Ca6[Al1-xFex(OH)6]2(SO4)3·26H2O), Author is Moschner, Goril; Lothenbach, Barbara; Winnefeld, Frank; Ulrich, Andrea; Figi, Renato; Kretzschmar, Ruben, the main research direction is solid solution aluminum iron ettringite phase composition.Category: isothiazole.

The solid solution between Al- and Fe-ettringite Ca6[Al1-xFex(OH)6]2(SO4)3·26H2O was investigated. Ettringite phases were synthesized at different Al/(Al + Fe)-ratios (= XAl,total), so that XAl increased from 0.0 to 1.0 in 0.1 unit steps. After 8 mo of equilibration, the solid phases were analyzed by X-ray diffraction (XRD) and thermogravimetric anal. (TGA), while the aqueous solutions were analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). XRD analyses of the solid phases indicated the existence of a miscibility gap between XAl,total = 0.3-0.6. Some of the XRD reflections showed two overlapping peaks at these molar ratios. The composition of the aqueous solutions, however, would have been in agreement with both, the existence of a miscibility gap or a continuous solid solution between Al- and Fe-ettringite, based on thermodn. modeling, simulating the exptl. conditions.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Aluminum(III) sulfate xhydrate(SMILESS: O=S(O)(O)=O.O=S(O)(O)=O.O=S(O)(O)=O.[H]O[H].[Al].[Al],cas:17927-65-0) is researched.Formula: C5H7N3S. The article 《Application of high rate ballasted flocculation technology in wet weather flow treatment》 in relation to this compound, is published in WEFTEC ’99, Annual Conference & Exposition, 72nd, New Orleans, Oct. 9-13, 1999. Let’s take a look at the latest research on this compound (cas:17927-65-0).

An innovative treatment technol. to address wet weather events is the ballasted flocculation process (e.g. Actiflo/Microsep from USFilter). The principal benefits of a ballasted flocculation treatment system for wet weather flows include vastly reduced space requirements, rapid start-up and response times, relative insensitivity to fluctuations in raw water quality, and removal rates greater than conventional systems. The key behind the ballasted flocculation process is the use of continuously recycled ballast or fine sand, which attaches to a flocculated particle through a polymer bridge. The addition of ballast provides 2 benefits: the high sp. gr. sand weights flocculated particles leading to much faster solids settling, and the increase in collision frequencies between sand and flocculated particles dramatically increases flocculation kinetics, resulting in very short mixing times. With rapid particulate settling and flocculation kinetics in ballasted flocculation systems, process design must focus on several fundamental parameters within the clarifier to maximize removal efficiencies and minimize plant footprint. This design approach was adopted in pilot testing of the USFilter ballasted flocculation process during wet weather flows at a variety of sites from 1997 through 1999. High quality, consistent effluent characteristics were achieved despite varying influent conditions. High quality effluent was produced within minutes of start-up, ideal for addressing transient wet weather or peaking events. Removal efficiencies through the ballasted flocculation process of over 85% for total suspended solids and over 60% for BOD were demonstrated. Even with a total hydraulic retention time of 6 min, sufficient residence time for mixing and flocculation was available, resulting in a very small footprint approach for wet weather treatment. With high levels of solids removal in a compact footprint, ballasted flocculation provides a cost competitive alternative to conventional clarification and biol. systems for treating wet weather flows.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Molten salt synthesis of mullite nanowhiskers using different silica sources, published in 2015-08-31, which mentions a compound: 17927-65-0, Name is Aluminum(III) sulfate xhydrate, Molecular Al2H8O13S3, Category: isothiazole.

Mullite nanowhiskers with Al-rich structure were prepared by molten salt synthesis at 1000°C for 3 h in air using silica, amorphous silica, and ultrafine silica as the silica sources. The phase and morphol. of the synthesized products were investigated by X-ray diffraction, SEM, energy dispersive spectroscopy, and transmission electron microscopy. A thermogravimetric and DTA was carried out to determine the reaction mechanism. The results reveal that the silica sources play an important role in determining the morphol. of the obtained mullite nanowhiskers. Clusters and disordered arrangements are obtained using common silica and amorphous silica, resp., whereas the use of ultrafine silica leads to highly ordered mullite nanowhiskers that are 80-120 nm in diameter and 20-30 μm in length. Considering the growth mechanisms, mullite nanowhiskers in the forms of clusters and highly ordered arrangements can be attributed to heterogeneous nucleation, whereas disordered mullite nanowhiskers are obtained by homogenous nucleation.

Decolorizing the molasses effluent of yeast and alc. fermentation processes was studied using inorganic salts and com. (organic and inorg) polymers. The effluents were decolorized either untreated or after an anaerobic/aerobic treatment. The color elimination attained was 86% with the anaerobic/aerobic effluent when adding 60 mg/L of Al3+ as Al2(SO4)3·18 H2O at pH=5.0. Removal of color to the same extent was also obtained when the inorganic polymer (500 mg/L from Flocusol-PA/18.B) or the organic polymer (2500 mg/L Nalcofloc plus 3 mg/L N677-SC) were added to the effluent at its original pH value of 8.0-8.5. Under these conditions, a 55% COD removal was also achieved. For the raw effluent, color and COD removal were <3% and 2%, resp. for all the reagents tested.

A novel preparation of aluminum diethylphosphinate (AlPi) was carried out with free-radical addition reaction by means of UV-irradiation under atm. pressure. A solution of sodium hypophosphite was treated with ethylene and irradiated with UV light in the presence of an amount of photoinitiator effective to initiate the free-radical reaction between the hypophosphite anion and the double bond of the ethylene mol. The ethylene was micro-bubbled into the reaction mixture with the addition of the photoinitiator, and the gas-liquid contact surface and the photoinitiator concentration in the gas-liquid interface were increased largely. The yield of the final product could be improved to about 96%. The contents of P, Al in samples were detected by ICP, and the mol. structure of the samples was confirmed by 31P NMR, 1H NMR and FTIR spectroscopic anal. Thermal stability of the final products was investigated in detail by TG-DTA.

Al was injected (i.p.) as aluminum sulfate (4, 40, and 100 mg/kg body weight, n = 5 per group) daily into day-old White Leghorn male chickens for 7, 15 and 30 days. Al treatment (100 mg dose) to chickens over 7 and 30 days resulted in a decrease in activities of cytosolic total and CN–sensitive superoxide dismutase (SOD) in the cerebral hemisphere (CH). In the 15-day treated group, activities of cytosolic total, CN–sensitive and CN–insensitive SOD of CH were decreased in response to all Al doses. In the liver, activities of cytosolic total and CN–sensitive SOD were decreased in response to all doses of Al treatment for 7 and 15 days. But 40 and 100 mg doses were effective in decreasing activities of the enzymes in the 30-day treated group. The catalase (CAT) activity of CH of chicks was inhibited by all doses of Al under treatment for 7 days, but was inhibited only in the case of the 100 mg dose when the duration of treatment was increased to 15 days. The inhibition was again observed in chickens treated for 30 days in response to 40 and 100 mg doses . CAT activity of liver was decreased in response to all Al doses in the 7-day treated group and in response to 40 and 100 mg doses in the 15- and 30-day treated groups. Al treatment did not affect lipid peroxide levels of CH and liver of chickens.
