General Description

Praseodymium dioxide, also known as praseodymia, is a chemical compound consisting of the rare earth element praseodymium and oxygen. It is a light yellow-green solid with high thermal stability. Praseodymium dioxide is commonly used as a pigment in ceramics, glass, and enamel, due to its ability to produce vibrant yellow and green colors. It is also used as a catalyst in the production of ammonia and in the manufacturing of specialty glasses and optical fibers. Additionally, praseodymium dioxide has potential applications in fuel cells, catalytic converters, and other advanced technological devices. Despite its limited commercial use, praseodymium dioxide plays an important role in various high-tech industries, contributing to the development of innovative materials and technologies.

Check Digit Verification of cas no

The CAS Registry Mumber 12036-05-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,3 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12036-05:
(7*1)+(6*2)+(5*0)+(4*3)+(3*6)+(2*0)+(1*5)=54
54 % 10 = 4
So 12036-05-4 is a valid CAS Registry Number.

Chlorination of Pr2O3 and Pr6O11. Crystal structure, magnetic and spectroscopic properties of praseodymium oxychloride

Pomiro, Federico J.,Gaviría, Juan P.,Fouga, Gastón G.,Vega, Leonardo D.,Bohé, Ana E.

, p. 919 - 926 (2019)

The reactions of Pr2O3 and Pr6O11 with Cl2(g) were studied thermodynamically and experimentally, and proposed in the systems Pr2O3/Cl2(g) and Pr6O11/Cl2(g). A kinetic analysis was performed on Pr6O11 chlorination, which differs from with other light rare earth oxide chlorinations. The praseodymium oxychlorides obtained by full chlorination of Pr6O11 at 425 °C and 800 °C are different, being well characterized by X-ray diffraction, scanning electron microscopy, magnetic susceptibility measurements and X-ray photoelectron spectroscopy. The crystal structures of the oxychlorides were refined with the Rietveld method. The comparison between the theoretical magnetic moment of Pr3+ and the estimated magnetic moment in the praseodymium oxychloride obtained at 425 °C revealed the presence of Pr3+ and Pr4+, whereas no significant difference was observed between the theoretical and the experimental values of Pr3+ obtained for the praseodymium oxychloride prepared at 800 °C. These observations are consistent with the analyses in the X-ray photoelectron spectra for both oxychlorides. Finally, a general formula of PrO1+xCl is proposed for the oxychlorides synthesized at T 800 °C.

Carboxylato-bridged 3D polymeric networks of Pr(III): Synthesis, crystal structure, magnetic property and thermal behavior

Zhao, Lang,Xu, Gong-Feng,Tang, Jinkui

, p. 160 - 164 (2010)

A novel polymeric carboxylato-bridged praseodymium(III) complex of fumarate, [Pr2(fum)3(H2O)4] ·5H2O (fum, fumarate dianion) has been synthesized and characterized by single-crystal X-ray diffraction studies, magnetic measurements and thermal studies. Single crystal X-ray structural determination reveals that it is a new porous three dimensional pillared layer framework with 1D channel for the accommodation of tetrameric water clusters. A preliminary treatment of the variable-temperature magnetic susceptibility using an expression including the ligand field effects and molecular field approximation leads to zJ′ = -1.60 cm-1, Δ = 0.5 cm-1 and g = 0.84, suggesting the existence of a weak antiferromagnetic coupling between the praseodymium ions.
