Exchange reactions of hydrogen with deuterium oxide have been studied over metal films. The observed pattern of activity, which is Pt >2; Rh > Pd ⪢ Ni, is inversely related to the strength of adsorption of oxygen on the metals. Exchange reactions o

Three different samples of precipitated chromic oxide gel were prepared, and their surface and catalytic properties were studied. The techniques of DTA, TGA, X-ray diffraction, and electron microscopy, together with adsorption measurements, have been

E.p.r. spectra of a dehydrated copper-exchanged X-type zeolite have been obtained which suggest that the copper (II) ions are distributed in at least two magnetically non-equivalent environments. The copper (II) ions in one of these environments exhi

The isomerization of but-1-ene was observed to occur readily over SnO2 at temperatures ca. 300 K. A feature was the formation of large amounts of butadiene as well as cis- and trans-but-2-ene. The major role played in the reaction by the catalyst was

Exchange reactions of 3,3-dimethylbut-1-ene (I) with D2O have been studied over four X-type zeolites, silica-alumina and magnesium oxide, and with D2 over some of the catalysts. The isomerization of I, in the presence of D2O or D2, to form 2,3-dimeth

The kinetics of the isomerization of n-butenes was studied in a static reaction system over synthetic, crystalline, sodium silica-alumina, known as Na13X, and over a series of copper 13X zeolites prepared by partial exchange of the sodium. It was sho
