If the desorption rate is second-order, as is often the case for hydrogen on a metal surface, so that appears in Eq. XVIII-1, an equation analogous to Eq. XVIII-3 can be derived by the Redhead procedure. Derive this equation. In a particular case, H2 on Cu3Pt(III) surface, A was taken to be 1 x 10 cm /atom, the maximum desorption rate was at 225 K, 6 at the maximum was 0.5. Monolayer coverage was 4.2 x 10 atoms/cm, and = 5.5 K/sec. Calculate the desorption enthalpy (from Ref. 110). 

Preparation of 4,5,6,7-tetrabromobenzotriazole and its tetrachloro analog by direct bromination or chlorination of benzotriazole is described in Section 5.01.7. However, other tetra-substituted benzotriazoles have to be constmcted from a suitably substituted benzene ring. Thus, treatment of pentamethylbenzene 1293 with fuming nitric acid in concentrated sulfuric acid provides 3,4,5,6-tetramethyl-l,2-dinitrobenzene 1294 in 66% yield. Using routine procedures, derivative 1294 is reduced with SnCl2 in aqueous HC1, and the obtained diamine 1295 is subsequently treated with NaNOz (in aq. HC1) to provide 4,5,6,7-tetramcthyl-l //-benzotriazole 1296 (Scheme 216) <2004BMC2617>. 

Grain legumes have also been processed into refined starch (10,11) and protein isolates (12,13,14) by procedures derived from the traditional corn starch and soybean protein industries (15). However, comparative data on product yields, composition and losses have not been published. A commercial plant for the wet processing of field pea into refined starch, protein isolate and refined fiber has been established in Western Canada. Little is known about the characteristics of the protein isolate or refined fiber product. Water-washed starch prepared from the air-classified starch fractions of field pea (16,17) and fababean (6) have been investigated for certain physico-chemical and pasting properties. Reichert (18) isolated the cell wall material from soaked field pea cotyledons and determined its fiber composition and water absorption capacity. In addition, the effects of drying techniques on the characteristics of pea protein Isolates have been determined (14).

The value of d is calculated by averaging step-scan observations at ends of the scan, and is not varied during the least-squares procedure. Derivatives are calculated analytically using expressions obtained by differentiating equation 1. Up to 10 iterations are allowed 3 to 5 are usually required. 

A related approach is to synthesize a polyphosphazene with an amino-drug linked directly to phosphorus through a side-group phosphorus-nitrogen bond. The procaine derivative shown in 3.91 is a typical example designed to release the local anesthetic as an adjunct to dental or minor surgical procedures. Derivatives that contain benzocaine,... 

Of various homocoupling procedures derived from the original Glaser process that are still used today, Hay s procedure [4] using catalytic amounts of the biden-tate complexing base TMEDA in polar solvents (e.g. acetone, dichloromethane or o-dichlorobenzene) is most utilized and is the method favored for preparing linear oligo- and polyacetylenes, as outlined in Scheme 2 [5]. 

The Hindeleh-Johnson procedure derives the amorphous component of the diffraction profile in a natural way as described in Section 2.2.1. An alternative technique is to determine the positions, amplitudes and widths of diffraction lines with a peak-finding algorithm (e.g. based on the second differential) and to subtract lines so found from the... 

The wave and pulse patterns of nonreactive separation processes, as well as the integrated reaction separation processes illustrated above, can be easily predicted with some simple graphical procedures derived from Eqs. (4) and (5). The behavior crucially depends on the equilibrium function y(x) in the nonreactive case, and on the transformed equilibrium function Y(X) in the reactive case. In addition to phase equilibrium, the latter also includes chemical equilibrium. An explicit calculation of the transformed equilibrium function and its derivatives is only possible in special cases. However, in Ref. [13] a numerical calculation procedure is given, which applies to any number of components, any number of reactions, and any type of phase and reaction equilibrium. 

Close up, when separation Z R and Z R2, the interaction is dominated by interactions of the closest parts of the two spheres. Using the remarkable procedure derived by Derjaguin, we can express the force FSS(Z Ri, R2) between two spheres in terms of the energy of interaction Gpp(Z) between two parallel planes whose separation is also Z [see the Prelude and Level 2, Subsection L2.3.C on the Derjaguin transform see also Eq. (L2.106) and Table S.l.a in Level 2] ... 

By using the King-Altman procedure, derive the steady-state rate equation for the following enzyme mechanism ... 

Resulting fragments are clustered and reclassified into sets of monomers for subsequent library design. The RECAP procedure derives not only suitable chemotypes but also appropriate building blocks for scaffold decoration. Since the monomers are extracted from biologically active compounds, there is a high likelihood that new molecules derived from them will contain biologically important motifs. 

More or less as a spin-off result of the foregoing analysis determining the transport coefficients, a rigorous procedure deriving the governing equations of fluid dynamics from first principles was established. It is stressed that in classical fluid dynamics the continuum hypothesis is used so that the governing... 

A series of computer-simulated chromatograms has been generated to test the validity of a procedure derived from the statistical model for calculating the number of randomly distributed components when many of them are obscured by overlap. Plots of the logarithm of the peak count versus reciprocal peak capacity are used for this purposTI TRese plots are shown to provide reasonable estimates of the total number of components In the synthetic chromatograms. 

In a second procedure, derived by Goto and co-workers, "- ELAs form from a water-in-oil emulsion. This method applies to a wider variety of proteins than the first method. 

The principle of derivative spectrometry consists of calculating, by a mathematical procedure, derivative graphs of the spectra to improve the precision of certain measurements. This procedure is applied when the analyte spectrum does not appear clearly within the spectrum representing the whole mixture in which it is present. This can result when compounds with very similar spectra are mixed together. 

Physical/chemical methods among these methods the ethanol fractionation procedures derived from the Cohn method are the most widely used, at least for albumin and immunoglobulins. They commonly incorporate several steps, in each of which compliance with specific requirements is decisive for products quality under proper conditions, some of these steps may also contribute to the effective reduction of potential viral contaminants. Therefore, there should be clear instructions for ethanol and protein concentration, with data on acceptable tolerances as well as the means of controlling them.
