Actual configuration

Reactor diluents and solvents. As pointed out in Sec. 2.5, an inert diluent such as steam is sometimes needed in the reactor to lower the partial pressure of reactants in the vapor phase. Diluents are normally recycled. An example is shown in Fig. 4.5. The actual configuration used depends on the order of volatilities. [Pg.100]

Whether an extraneous component, product, or feed is used as a heat carrier, the actual configuration, as before, depends on the order of the volatilities (again assuming distillation as the means of separation). [Pg.101]

Liquid-Liquid Extraction The actual configuration of mixers in multistage mixer-settlers and/or multistage columns is summarized in Section 15. A general handbook on this subject is Handbook of Solvent Extraction by Lowe, Beard, and Hanson. This handbook gives a comprehensive review of this entire operation as well. [Pg.1640]

Whether an extraneous component, product, feed, byproduct or feed impurity is used as heat carrier, as before, the actual configuration of the separation configuration will change between different processes as the properties on which the separation is based change the order of separation. [Pg.262]

Simple spectrometers that cover the region from 350 to 1000 nm are available for modest cost and are useful for routine analysis. These spectrometers are usually single beam instruments that are set up according to the block diagram in Fig. 5.15, and Fig. 5.16 illustrates the actual configuration of a commercial instrument. [Pg.146]

The actual configuration of the reactor may take various forms depending on the precise requirements of the process. For example, for a high-temperature homogeneous gas-phase reaction such as naphtha cracking, the reactor may be simply a long tube in a furnace [Fig. 6(a)]. In other cases, the single tube is replaced by a number of tubes in parallel as shown in Fig. 6(b). [Pg.62]

Our opinion is that the actual configuration of oximes 37 should be inverted. Nitrosation of 36 in the presence of an alcoholate should result in the two E and Z oximes the Z isomer will suffer a spontaneous base-induced rearrangement into the furazan 39 and will not be isolated. Furthermore, the reported spectroscopic data agree with the inverted configuration. The intermediacy of open-chain species in the rearrangement... [Pg.59]

This section presents computational results of the models and the sampling scheme proposed in this chapter. The refinery examples considered represent industrial-scale size refineries and an actual configuration that can be found in many industrial sites around the world. In the presentation of the results, we focus on demonstrating the sample average approximation computational results as we vary the sample sizes and compare their solution accuracy and the CPU time required for solving the models. [Pg.148]

Because shifting a single electron from 4s to the energetically similar 3d level half-fills the 3d set, the actual configuration of chromium is... [Pg.290]

However, the optical activity does not tell us the actual configuration of an enantiomer. It only gives us the information whether an enantiomer rotates the plane-polarized light clockwise or anti-clockwise. [Pg.46]

FIGURE 7-2 Three ways to represent the two stereoisomers of glyc-eraldehyde. The stereoisomers are mirror images of each other. Ball-and-stick models show the actual configuration of molecules. By convention, in Fischer projection formulas, horizontal bonds project out of the plane of the paper, toward the reader vertical bonds project behind the plane of the paper, away from the reader. Recall (see Fig. 1-17) that in perspective formulas, solid wedge-shaped bonds point toward the reader, dashed wedges point away. [Pg.240]

Even when a successful resolution is achieved, some significant problems remain. For instance, the resolution itself does not provide information on the actual configuration of the (+) or (—) enantiomer. This must be determined by other means (see Section 19-5). Also, it is not possible to tell the enantiomeric purity (optical purity) of the resolved enantiomers without additional information. This point is discussed further in the next section. [Pg.870]

The configuration of Cr differs from that derived by the Aufbau procedure. Deduce the actual configuration and explain the anomaly. [Pg.127]

Ans. Cr [Ar] 3d5 4s1. Aufbau would give 3d44s2, so an s shifts to d to gain the stability of the half-filled subshell. Note that the actual configuration has complete spherical symmetry. [Pg.127]

These results may be analyzed as follows without knowledge of actual configurations. The two citrate samples must, from the mode of synthesis, be labeled at the same methylene (either pro-R or pro-S) one of them must contain 2H as Hr, the other as Hs of this methylene. They can be represented as follows ... [Pg.94]
