The special application of iron-manganese oxide nanocatalysts has been investigated in decomposition of hydrogen peroxide. In this research, iron-manganese oxide nanocomposites were synthesized by co-precipitation, sol-gel and mechanochemical methods using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared on the variou...

In this research, we have developed cheap recyclable and task-specific acidic ionic liquids (AILs) 1-hydrogen-3-methylimidazolium hydrogen sulfate [Hmim]HSO4, 1-hydrogen-3-methylimidazolium chloride [Hmim]Cl, 2-pyrrolidonium hydrogensulfate [Hnhp]HSO4 and applied them in acid catalyzed synthesis of quinoxaline derivatives from 1,2-phenylendiamines and 1,2-dicarbonyl compounds. The products coul...

The crystal structure of the title salt, C(5)H(6)NO(+)·HSO(4) (-), consists of planar(r.m.s. deviation = 0.001 Å) 4-hydroxy-pyridinium cations and hydrogen sulfate anions which are hydrogen bonded into a layer motif. In the anion, the S-O bond [1.551 (2) Å] involving the O atom bearing the acid H atom is longer than the other three S-O bonds, which range from 1.437 (1) to 1.454 (1) Å.

The term ‘conjugated estrogens’ refers to mixtures of at least eight compounds, including sodium estrone sulfate and sodium equilin sulfate, derived wholly or in part from equine urine or synthetically from estrone and equilin. Conjugated estrogens contain as concomitant components the sodium sulfate conjugates of 17α-dihydroequilin, 17β-dihydroequilin, and 17α-estradiol (United States Pharmaco...

Desulfovitio d&dfUTiCam is an obligately anaerobic organism that can bc grown heterotrophically with sulfate and an organic electron donor or autotrophically with sulfate, hydrogen, and CO* (1). The presence of sulfate is obligatory for growth both with hydrogen and organic electron donors, except in the case of pyruvate (2). During growth, large amounts of sulfide are produced from the sulfate...
