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 Effects of milling of starting hydrated aluminum sulfate on η → α phase transformation and sinterability of alumina, published in 1986-02-01, which mentions a compound: 17927-65-0, mainly applied to aluminum sulfate hydrate milling alumina; sintering alumina precursor milling; dehydration alumina precursor milling, HPLC of Formula: 17927-65-0.

The effects of milling of the precursor, Al2(SO4)3 (14-18)H2O, on η → α phase transformation and sinterability of α-Al2O3 were studied. Milling of the hydrated sulfate lowered the temperatures of dehydration, desulfation, and η → α phase transformation by about 30°, 20°, and 100°, resp. Dehydration of hydrated sulfate produced broken-eggshell-like anhydrous sulfate particles through melting of the hydrate in its water of crystallization On heating, the milled hydrated sulfate converted to anhydrous particles composed of finer sulfate particles. The anhydrous sulfate desulfated into aggregate grains of η-Al2O3 with an irregular pore size distribution. This η-Al2O3, finally formed skeletal grains of α-Al2O3 in which many cracks were produced. The optimum calcination temperature to prepare α-Al2O3 powder for sintering was lowered and the sinterability was improved by the milling treatment. The slope of Avrami-plots for η → α phase transformation indicated a 2-dimensional growth of α-Al2O3. The apparent activation energy for the transformation was 110 kcal/mol, which remained unchanged with milling. The enhancement of η → α phase transformation was due to accelerated nucleation in η-Al2O3 grains, and the sinterability of the α-Al2O3 was improved by an increase in the d. of green compacts, resulting from the occurrence of many cracks in the skeletal grains of α-Al2O3.

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.

Name: Aluminum(III) sulfate xhydrate. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about Tribochemistry and kinetics of Al2(SO4)3.xH2O decomposition. Author is Pelovski, Y.; Petkova, V..

The thermal decomposition of tribochem. activated Al2(SO4)3.xH2O was studied by TG, DTA and EMF methods. For some of the intermediate solids, x-ray diffraction and IR-spectroscopy were applied to learn more about the reaction mechanism. Thermal and EMF studies confirmed that, even after mech. activation of Al2(SO4)3.xH2O, Al2O(SO4)2 is formed as an intermediate. Isothermal kinetic experiments demonstrated that the thermochem. sulfurization of inactivated Al2(SO4)3.xH2O has an activation energy of 102.2 kJ.mol-1 in the temperature range 850-890 K. The activation energy for activated Al2(SO4)3.xH2O in the range 850-900 K is 55.0 kJ.mol-1. The time of thermal decomposition is almost halved when Al2(SO4)3.xH2O is activated mech. The results permit conclusions concerning the efficiency of the tribochem. activation of Al2(SO4)3.xH2O and the chem. and kinetic mechanisms of the desulfurization process.
