Über die Reduktion von Eisenchloriden mit Wasserstoff

Abstract: Inhaltsiibersicht Es werden die Zersetzungsgleichgewichte des festen Eisen(II1)-chlorids und seines dimeren Dampfes in Eisen(II).chlorid und Chlor untersucht und berechnet. Der Zedall dee festen Sakes nimmt mit steigender Temperatur zu, derjenige des dimeren Dampfes dagegen ab. Die &hnungen ergeben fur die Standartentropie des festen Eisen(m)chlorids 36,9 cl, fur diejenige des dimeren Dampfes 142,2 cl. Auf Grund diesex Ergebnisse werden die von STIRNEMANH. gemessenen Dampfdrucke des Eisen(II1)-chlorids neu ber… Show more

“…To derive Fe2CI6 partial pressures from manometric measurements of the total pressure, one must also consider the decomposition reaction 4. Reaction 4 at lower temperatures Fe2CI8(g) = 2FeCI2(s) + Cl2(g) (4) is slow to equilibrate (10,24), and equilibrium constants derived by various investigators are not in close agreement (10,14,25,26). We have used eq 5, based on thermodynamic con-Ko, = Pcl2/PD = exp(31157"1 -8.369) (5) stants at 500 K given in the JANAF tables (2,27), to predict the contribution of chlorine when both FeCI2(s) and FeCI3(s) are present.…”

“…Sublimation vapour pressures of FeCl 3 (cr) have been made using manometric [4][5][6][7], transpiration [6,9,10], Knudseneffusion [11,12], and spectrophotometric [13,14] techniques. Dynamic studies of FeCl 3 (cr) [6,10,11,15] and Fe 2 Cl 6 (g) [6,15,16] decomposition indicate that equilibration is slow. These studies, suggest that a direct study of the sublimation of FeCl 3 (cr) to the dimeric vapour should be possible using the Knudsen-effusion method without the complication of a concomitant chlorine partial pressure.…”

“…Anhydrous manganese halides are available upon reaction of the corresponding acetyl halide with manganese acetate . Because of the inertness of Fe 2 O 3 , anhydrous iron(II) halides are also prepared from the metal. , The microwave-assisted synthesis of FeCl 2 under modified conditions is also described . Cobalt(II) halides are produced starting from CoCO 3 , and the acetyl halide or alternatively CoCl 2 ·6H 2 O is subsequently dehydrated with SOCl 2 .…”
