oil has the advantage that the three-phase interval of the ternary system A-B-C is raised above the melting point so that the phase behavior of the system can be studied from = e = 0 into the quinary system at ambient temperatures.Acknowledgment. We are indebted to Mrs.

The anionic hydride HFe3(CO)11− species grafted in the zeolite by ionic interaction with an Al3+ ion showed high catalytic activity for the water gas shift reaction, which was comparable to that of iron carbonyl in homogeneous phase. Kinetic and spectroscopic measurements indicated a reaction of HFe3(CO)11− with H2O as a rate determining step.

Bei Sublimation von (I) auf hydratisiertes Na‐Y Zeolith deuten Farbänderung und IR‐Spektren auf schwache Wechselwirkung zwischen Carbonylliganden und Zeolithgerüst.
