The thermal decomposition of Al2(SO4)3.-nH2O and Hf(SO4)2.4H23 was studied in air by thermogravimetry and in vacuum by simultaneous thermogravimetry and evolved-gas analysis. No SO2 was detected by the mass spectrometer. The primary products of decomposition appear to be SO and O2 for both sulfates. For the Al salt, the Arrhenius relationship shows 2 activation energies, whereas for the Hf salt there is only 1 activation energy in vacuum and 2 activation energies in air. X-ray data show the solid products of the reactions to be η-Al2O3 and HfO2. The diffraction pattern for Hf(SO4)2.4H2O is presented.

Product Details of 17927-65-0. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about Deuterium/hydrogen fractionation in sulfate hydrate-water systems. Author is Pradhananga, Trinetra M.; Matsuo, Sadao.

The D/H fractionation factors (α) of some of the sulfate hydrate-H2O systems were measured. A dependence of α on cationic parameters and M-H2O distance was found. The D/H fractionation factors of various hydrate-water systems were divided into 2 groups with respect to their α values: one having α < 1 and the other α > 1. There is almost no change in α for crystal-H2O systems having SO42- as the anion of the 1st transition metal ion series from Fe2+ to Zn2+, except for Cu2+. This is related to the common structure of the hydration sphere of cations and the common distance of M-H2O. The exceptional case for Cu2+ is attributed to the distorted structure of octahedra surrounding Cu2+. A similar type of behavior of protons leading to the residual entropy was found in some of the crystal-H2O systems having α > 1.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you 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, mainly applied to silica molten salt mullite nanowhisker, SDS of cas: 17927-65-0.

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.

Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about Decolorization of molasses effluents by coagulation-flocculation process. Author is Gonzalez Benito, Gerado; Pena Miranda, M.; Garcia Cubero, M. T.; Uruena Alonso, M. A..

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.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Yang, Li; Han, Xin Yu; Tang, Xue Jiao; Han, Chang Xiu; Zhou, Yi Xiao; Zhang, Bao Gui researched the compound: Aluminum(III) sulfate xhydrate( cas:17927-65-0 ).Safety of Aluminum(III) sulfate xhydrate.They published the article 《A novel photoinitiated approach for preparing aluminum diethylphosphinate under atmospheric pressure》 about this compound( cas:17927-65-0 ) in Chinese Chemical Letters. Keywords: aluminum diethylphosphinate preparation photoinitiated radical addition hypophosphite anion ethylene. We’ll tell you more about this compound (cas:17927-65-0).

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.

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 Synthesis of hydrated aluminum sulfate from kaolin using microwave energy, published in 1998-08-31, which mentions a compound: 17927-65-0, Name is Aluminum(III) sulfate xhydrate, Molecular Al2H8O13S3, Category: isothiazole.

Hydrated aluminum sulfate, an inorganic polymer, was synthesized from kaolin in H2SO4 solution using microwave energy. The maximum rates of alumina extracted from calcined kaolin were 72.8% in a conventional process (80°, 1M, and 180 min) and 99.9% in a microwave process (90°, 1M, and 60 min). Compared with the conventional one, the hydrated aluminum sulfate synthesized under the microwave process had layer structure consisting of plate-shaped large grains. After synthesis and then calcination at 1100°, both products in conventional and microwave processes were γ-Al2O3 with agglomerated powders of spherical shape. The specific area of the products in conventional and microwave processes were 113.5 and 106.6 m2/g, and their average grain sizes were 46.5 and 26.3 μm, resp.
