Thermodynamic properties of silicides. II. Heat capacity at temperatures T from 5.9 K to 341 K and derived thermodynamic properties to T = 1200 K of tungsten disilicide: WSi2.06
(Elsevier, 1993-11)
The heat capacity of tungsten disilicide WSi2.06 was measured over the temperature range 5.9T/K)-2[middle dot]mol-1. For the lattice, the Debye characteristic temperature [Theta]CD = (317.8+/-3.3) K. From our results, the ...
Thermodynamics of alkali alkanoates IX. Heat capacity and thermodynamic functions of lithium 2-methylpropanoate at temperatures from 7 K to 535 K
(Elsevier, 1993-10)
The heat capacity of lithium 2-methylpropanoate was measured by equilibrium adiabatic calorimetry at temperatures, T from 7 K up to 350 K and by d.s.c. from 330 K through melting to 535 K. A small diffuse hump was observed ...
The synthesis of DL-3,3-Difluoroglutamic acid from a 3-oxoprolinol derivative
(Elsevier, 1993-07-30)
DL-3,3-Difluoroglutamic acid was synthesized from a masked 3-hydroxyprolinol, 6-hydroxy-1-aza-3-oxabicyclo[3.3.0]octan-2-one, in eight steps. The described synthetic route expands the utility of fluoroproline derivatives ...
Thermodynamics of divalent-metal fluorides VI. Heat capacity and thermodynamic properties of the fast-ion conductor CaSn2F6 at temperatures from 6 K to 310 K
(Elsevier, 1993-02)
The molar heat capacity Cp. m of calcium hexafluorostannate CaSn2F6 was measured at temperatures T from 6 K to 310 K by adiabatic calorimetry. Reproducible heat capacities were obtained only after cooling the sample twice ...
Diimide formation on the Ni(100) surface
(Elsevier, 1993-06-10)
Diimide (N2H2), an extremely reactive species, is observed as a gas phase product from the Ni(100) surface in the 200 to 450 K range during hydrazine thermal decomposition and during thermal desorption of predissociated ...
Adsorption and thermal decomposition of CH3SH on the Pt(111) surface
(Elsevier, 1993-12-01)
Adsorption, desorption and thermal decomposition of methanethiol (CH3SH) on a clean and on a (2 x 2)-S covered Pt(111) surface have been studied using temperature programmed desorption, high resolution electron energy ...
Axial selectivity of 1,2-nucleophilic additions to 2-(Alkylidene)cyclohexanones: Is it higher than that of 2-cyclohexenones?
(Elsevier, 1993-04-23)
2-(Alkylidene)cyclohexanones embedded in steroid systems underwent 1,2-addition of both small and sterically demanding nucleophiles to yield exclusively the axial adducts, supporting the suggestion that 2-(alkylidene)cyc ...
The preparation of (Z)-2-lithio-ortho-styryllithium via an ortho-directed lithiation
(Elsevier, 1993-11-30)
Lithiation of (Z)-2-lithiostyrene with t-butyllithium/TMEDA pentane led directly to (Z)-2-lithio-ortho-styryllithium. Subsequent treatment of this dilithio compound with difunctional electrophiles allowed the preparation ...
