This work provides evidence that though NH3 instrumentation have greatly progressed in measurement precision, there is still further work required to quantify the accuracy of these systems under field conditions. It is the recommendation of this study that the use of instruments...
The increased number of Lewis acid sites and weak acid sites and the optimal ratio of Re 4+ /Re 7+ of Re-H3PW12O40/TiO2 were favorable for the formation of DMM2 from DME oxidation. The possible reaction pathway of DME oxidation to DMM2 was proposed.Qingde...
The results reveal that the K-free Ir/Al2O3 catalyst consists mainly of the IrO2 phase, exhibiting also significant Lewis acidity, which is gradually eliminated by the addition of K. Catalytic performance results showed that the deN2O performance in the absence of O2 in the feed mixture is ...
The Lewis bases B involved are N2, CO, PH3, C2H2, C2H4, H2S, HCN, H2O and NH3. Plots of De versus NB, where the NB are the nucleophilicities assigned to the Lewis bases previously, are good straight lines through the origin, as are those for the corresponding set of complexes B·...
Photolysis of 6 in liquid ammonia gives [Cb*Co(NH3)3]PF6 (9). Compound 8 is substitution-labile and reacts with a wide variety of Lewis bases to produce substitution products [Cb*CoL3]PF6 with L = P(OMe)3 (10), py (11), CNtBu (12), and the related compound (NEt4)2[Cb*...
