Note on the kinetics of the catalytic hydrogenation of benzene on a supported nickel catalyst
Wiley - Tập 12 Số 2 - Trang 73-75 - 1962
The kinetics of the catalytic hydrogenation of benzene on supported nickel and nickel oxide catalystsAbstract In the development of a pilot unit for studying reactions involving heterogeneous catalysis a nickel catalyst was selected for the initial study, and the hydrogenation of benzene in a fluidized reactor using nickel and nickel oxide supported on silica gel was investigated for the reaction C6 H6 + 3 H2... hiện toàn bộ

Electrical measurements in the study of immersed paint coatings on metal. I. Comparison between capacitance and gravimetric methods of estimating water‐uptakeAbstract An electrical capacitance method of estimating the water‐uptake of paint films on metal immersed in sea‐water has given, for many paint formulations, values agreeing with those obtained by a gravimetric method. For a few paints, however, pronounced disagreement was shown between values obtained by the two methods. Theoretical considerations ... ... hiện toàn bộ

Catalytic synthesis of ethyl propionate from diethyl ether and carbon monoxide at high pressureAbstract The catalytic synthesis of ethyl propionate from diethyl ether and carbon monoxide has been studied in the presence of nickel, cobalt and iron catalysts at a pressure range of 175–375 atm., and temperature range of 200–300°. Of the various catalysts tested, the iodides of iron, cobalt and nickel, supported on silica gel, exhibit the maximum catalytic activi... ... hiện toàn bộ

An improved method for the calculation of pore size distribution from adsorption dataAbstract A method for calculating the pore size distribution from adsorption isotherms on porous solids is described, which is more exact and less tedious to use than some previously described methods. The method of compiling tables for calculation is shown and an example of such a calculation is given.

The surface properties of precipitated alumina. I. Preparation of active samples and determination of nitrogen adsorption isothermsAbstract Alumina precipitates have been prepared by treating sodium hydroxide with either aluminium chloride, or sulphate, at pH 5. Adsorption isotherms of nitrogen, determined at −196°on the outgassed products, were all of reversible S‐type, characteristic of physical adsorption on non‐porous solids. Surface areas have been calculated by the usual Brunauer, Emmett ... ... hiện toàn bộ

Investigations on organo‐tin compounds. VIII. preparation of some organo‐tin hydridesAbstract The preparation, according to the slightly modified procedure of Finholt et al. , of the following organo‐tin hydrides is described: triethyltin hydride, tri‐n ‐propyltin hydride, tri‐n ‐butyltin hydride, triphenyltin hydride, di‐n ‐propyltin dihydride, d... ... hiện toàn bộ

Thermal stability of p‐phenylene sulphide polymersAbstract The thermal stability of a series of linear and branched p ‐phenylene sulphide polymers at 350° has been evaluated by differential thermal analysis, thermogravimetric analysis and weight‐loss studies. It has been concluded that there is some indication that the thermal stability increases with the degree of branching present in the... ... hiện toàn bộ

Three methods for the determination of the degree of substitution at protein‐amino groups with special reference to substituted gelatinsAbstract Three methods for the determination of the degree of substitution at protein‐amino groups are examined and compared. The procedures are applied to benzenesulphonyl derivatives of gelatin. The formol titration and ninhydrin colorimetric procedures are generally applicable to soluble proteins and their soluble derivatives. The spectrophotometric method is als... ... hiện toàn bộ

Synthesis and properties of some gelatin derivatives with substituents at the amino groupAbstract Gelatin has been interacted with benzenesulphonyl chloride and with other sulphonyl chlorides to give sulphonyl‐gelatin derivatives. With dichloro‐s ‐triazines, gelatin afforded crosslinked products or monofunctionally substituted soluble products according to the reactivity of the dichloro‐s ‐triazine sel... ... hiện toàn bộ
