Über die Bildungsenthalpie des Calciumcarbids

Abstract: InhaltsiibersichtMittels eines empfindlichen anisothermen Fliissigkeitscalorimeters wurde bei 18 "C in 0,5 n HCI die Zersetzungswiirme 94 bis 98proz. Calciumcarbids zu -G0,3 j , 0,2 kcal/Mol und die Losungswiirme 99,6proz. Calciums zu -128,7 i 0,2 kcal/Mol bestinimt. Unter Verwendung der von ROSSINI ermittelten Bildungsenthalpie des Acetylens errechnet sich fur die Bildungsenthalpie des Calciumcarbids ein Wert von -14,2 + 0,4 kcal/MoI.

“…The dialkyl phosphonates (28-36) were obtained in 94-98% yields after flash column chromatography. Compounds 28-36 known from the literature [20][21][22][23][24][25][26] were identified on the basis of 31 P NMR and HRMS. Two species (34 and 36) lacking 31 P NMR chemical shifts were analyzed also by 1 H and 13 C NMR spectral data.…”

“…A few systems containing X-heterocyclic ring systems have been studied, among these are pyrimidine (303) and pyrazine (304) in the liquid and solid states, including deuterated species, and also molten pyridine X-oxide (236) and piperidine for which a chair conformation is indicated (207). Several polycrystalline trihalogenated anilines have been examined (188, 342), the series of nitro compounds CHs-(CH2)n-XO2 (71 = 0.1----9) (106). There has been extensive work on nitriles, acetonitrile has been studied in the liquid state (245), and complexed with ZnCl2 (94), where the Zn attaches to the lone pair electrons of the nitrogen atom and the C=N force constant increases.…”
