G. J. M. van der Kerk, J. G. NOLTES, J. G. A. Luijten
AbstractThe 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
Influence of silica on the hydration of 3 CaO,SiO2Wiley - Tập 14 Số 8 - Trang 338-346 - 1964
H.N. Stein, J. M. Stevels
AbstractAmorphous silica accelerates the hydration rate of 3CaO,SiO2. This acceleration can be explained by assuming that the silica, by lowering calcium‐ and hydroxyl‐ion concentrations during the first minutes of the hydration, increases the conversion rate of a first protective hydrate layer into another less protective one....... hiện toàn bộ
Hydration of tricalcium silicateWiley - Tập 17 Số 9 - Trang 246-250 - 1967
J. G. M. de Jong, H.N. Stein, J. M. Stevels
AbstractResults of following the quantities of free Ca(OH)2 and of tricalcium silicate (C3S) during the hydration of C3S, and also the influence of the presence of free CaO on this reaction are in accordance with the hypothesis of Stein & Stevels with regard to the hydration of C3... hiện toàn bộ
Thermal stability of p‐phenylene sulphide polymersWiley - Tập 17 Số 10 - Trang 269-275 - 1967
Robin M. Black, C. F. List, RJ Wells
AbstractThe 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
Catalytic synthesis of ethyl propionate from diethyl ether and carbon monoxide at high pressureWiley - Tập 12 Số 4 - Trang 174-182 - 1962
S. K. Bhattacharyya, Sourav Palit
AbstractThe 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
The polyphosphates of calcium, strontium, barium and magnesium: Their complex character, composition and behaviourWiley - Tập 4 Số 8 - Trang 419-429 - 1954
M. Bobtelsky, S. Kertes
AbstractA study of pyro‐ and tripoly‐phosphates, by heterometric (photometric study of suspensions), pH and conductometric methods, was made on a quantitative basis. From the curves obtained, the composition and properties of the salts and complexes, which exist in solution or in the solid state, were deduced. All three methods gave results that were in complete ac...... hiện toàn bộ
The kinetics of the catalytic hydrogenation of benzene on supported nickel and nickel oxide catalystsWiley - Tập 7 Số 1 - Trang 1-14 - 1957
R. L. Motard, R. F. Burke, Lawrence N. Canjar, Robert B. Beckmann
AbstractIn 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 C6H6+ 3 H2... hiện toàn bộ
