Considering this equation, the increment in conductivity of the reaction mixture during the reaction indicates the silver ions were progressively exchanged for more mobile H+ ions. This supports this proposed mechanism (Pastoriza-Santos and Liz-Marzán, 1999). Like other methods of synthesis of silver...
A total of 17 ylides 361 were readily prepared by treating the corresponding phosphonium salts (R1 = Ph, Bun) with n-butyllithium followed by the appropriate acid chloride (0.5 equiv.) (Equation (54), Table 5) <1997JCS(P1)3107>. (54) Table 5. Preparation of benzotriazoyl ylides 361 36...
Chemoenzymatic cascade catalysis has emerged as a revolutionary tool for streamlining traditional retrosynthetic disconnections, creating new possibilities for the asymmetric synthesis of valuable chiral compounds. Here we construct a one-pot concurrent chemoenzymatic cascade by integrating organobismuth-catalyzed...
The velocity field in the reactor is described by the Hagen-Poiseuille equation for fully developed laminar flow. This is described by a parabolic expression with respect to the radius. Only a 2D cross section (light blue) of the reactor needs to be modeled due to axial symmetry. The ...
13C NMR chemical shifts for some α-heterosubstituted acetones were recorded. The carbonyl carbon shieldings are discussed in the light of the substituent electronic effects and were also empirically estimated by Tanaka et al.'s equation. An approximate linear relationship was observed between the ...
It is shown by the discussion of the wave equation for a diatomic molecule in a crystal that the motion of the molecule in its dependence on the polar angles 胃 and 蠁 may approach either one of two limiting cases, oscillation and rotati... Pauling,Linus - 《Physical Review》 被引量: ...
The crystallite size (CS) of the natural fiber were calculated through the following equation40; $${\text{CS}} = [0.89\lambda /\beta \cos \theta ]$$ (2) where, β is the full-width at half-maximum (FWHM) value of peaks; θ is the Bragg’s angle41. ...
a shortlist of 11 metabolites has been proposed as being suitable for providing the characteristics for detecting people with sufficient concentrations for current sensitive and selective analytical techniques, namely CO2, ammonia, acetone, 6-methyl-5-hepten-2-one, isoprene, n-propanal, n-hexanal, ...
Equation-Oriented Simulation and Optimization of Process Flowsheets Incorporating Detailed Spiral-Wound Multistream Heat Exchanger Models Multiple chemical processes rely on multistream heat exchangers (MHEXs) for heat integration, particularly at cryogenic temperatures. Owing to their geomet... C Tsay,RC...
