An Unexpected Controlled New Oxidant: SO4(·-).
A controlled new oxidant sulfate radical anion (SO4(·-)) was found and it can be easily prepared by mixing Na2S2O4 and TBHP with stirring. In this new metal-free oxidation system (Na2S2O4/TBHP), SO4(·-) can be used as a controllable oxidant to oxidize various aromatic alcohols to the corresponding aldehydes in good yields without any acid formation at room temperature. SO4(·-) was determined by...
متن کاملRedetermination of tamarugite, NaAl(SO4)2·6H2O
The crystal structure of tamarugite [sodium aluminium bis-(sulfate) hexa-hydrate] was redetermined from a single crystal from Mina Alcaparossa, near Cerritos Bayos, southwest of Calama, Chile. In contrast to the previous work [Robinson & Fang (1969 ▶). Am. Mineral. 54, 19-30], all non-H atoms were refined with anisotropic displacement parameters and H-atoms were located by difference Fourier me...
متن کاملSchaurteite, Ca3Ge(SO4)2(OH)6·3H2O
This report presents the first crystal structure determination of the mineral schaurteite, ideally Ca(3)Ge(SO(4))(2)(OH)(6)·3H(2)O, tricalcium germanium bis-(sulfate) hexa-hydroxide trihydrate. This single-crystal X-ray diffraction study investigated a natural sample from the type locality at Tsumeb, Namibia. Schaurteite is a member of the fleischerite group of minerals, which also includes fle...
متن کاملPraseodymium(III) sulfate hydroxide, Pr(SO4)(OH)
The title compound, Pr(SO(4))(OH), obtained under hydro-thermal conditions, consists of Pr(III) ions coordinated by nine O atoms from six sulfate groups and three hydroxide anions. The bridging mode of the O atoms results in the formation of a three-dimensional framework, stabilized by two O-H⋯O hydrogen-bonding inter-actions.
متن کاملAdsorption of nitrate from aqueous solution using activated carbon-supported Fe0, Fe2 (SO4)3, and FeSO4
In this laboratory scale study, impregnated almond shell activated carbon was used as adsorbent to investigate its feasibility for nitrate adsorption from aqueous medium. The effects of activated carbon dosage and contact time have been examined in batch experiments. Experimental data show that impregnated activated carbons by Fe0, Fe2 (SO4)3, and FeSO4 were more effective than virgin almond ac...
