Using electrodeposition from a bath of molten fluorides, single crystals of tetragonal beta-tantalum have been obtained for the first time at normal pressure. The unit-cell parameters are a = 10.211 (3), c = 5.3064 (10) Angstrom, space group P (4) over bar ...
Industry requires continuously new chemical processes to convert raw materials to valuable products limiting the formation of by-products. Since a few years, an increasing interest has been given to the intensification of chemical processes. This represent ...
The alcoholate-promoted dehydrohalogenation of 5-nonyl fluoride and cyclododecyl fluoride, typical straight-chain and, resp., medium-size cyclic substrates, leads to cis- and trans-alkenes in an approx. ratio of 1:3. With bulky bases such as lithium diisop ...
Low temp. 31P NMR indicated that the reaction of Ph3P+C-RR1 (I, R = R1 = H, Me) with R2COR3 (R2 = R3 = H; R2 = Ph, R3 = H) under salt free conditions gave the corresponding oxaphosphetane (II); in the presence of Li salts, esp. in Et2O, Ph3P+CRR1CR2R3OLi X ...
We have performed an ab initio mol. dynamics (MD) simulation of the structure of liq. hydrogen fluoride. Our results exhibit a strong contraction of the hydrogen bond in going from the gas to the liq. phase. The local structure of the liq. resembles that o ...
Results concerning the coupling of the steam reforming and total oxidn. of methanol in a two-passage reactor are presented. A com. available copper-based catalyst is used for the steam reforming. For the total oxidn., a highly active cobalt oxide catalyst ...
A new cubic Ta-bronze (1) KTa1+z+(5-delta)O3 [z similar or equal to 0.107 (3)] was obtained on a cathode by molten salt electrolysis of the system K2TaOF5-K3TaO2F4-(KF + NaF + LiF)(cutectic). Black, metallic cubic crystals of (1) are formed together with t ...
Hydrogen for fuel cell application can be produced autothermally by the combination of endothermic steam-reforming and exothermic oxidn. of methanol, called oxidative steam-reforming of methanol (OSRM). To enhance this reaction, the novel of a microstructu ...
The aim of this work is to develop a microstructured reactor based on filamentous catalysts for the Oxidative Steam-Reforming of Methanol (OSRM), to produce hydrogen as feed for a fuel cell, in an autothermal way. Hydrogen is produced by the methanol Steam ...
The aim of this work was to operate the steam reforming of methanol and the total oxidation of methanol in a microstructured two-passage reactor. The steam reforming enables the production of hydrogen at relatively low temperatures (250 °C) with only a sma ...
