Conversion tables temperature conversions

NOTE An extensive table of temperature conversions may be found in the sixth edition of the Handbook (Table 1-12). 

Table 7-10 pre.sents a temperature conversion table for various metals from one manufacturer for conventional pre-bulged, ten-sion-loaded disks with pressure on concave side (not prescored) as an illustration of the effect of lower or elevated temperatures referenced to 72°F on the burst pressure of a stamped disk. For other types of disk designs and from other manufacturers, the specific data for the style disk must be used to make the appropriate temperature correction.

Referring to each amine shown in Table 11.5, as the temperature increases so the dissociation constant Kb decreases (although ratios between amines may change). Conversely, as temperature decreases, so Kb increases. Generally, because we are concerned with relatively high temperatures, the Kb value is likely to be lower than shown in some published tables, and so more product will be required than possibly anticipated. 

We can see from Table 9.2 that the equilibrium constant depends on the temperature. For an exothermic reaction, the formation of products is found experimentally to be favored by lowering the temperature. Conversely, for an endothermic reaction, the products are favored by an increase in temperature.

Figure 4 shows the evolution of the initial conversion versus temperature at a space velocity of 0.03 h l. The equilibrium conversion of isobutane to isobutene is 100% in our conditions. An increase of the conversion with temperature up to 773-823 K is observed. When metals were added, we also noted a large increase in isobutane dehydrogenation. Table 2 gives initial isobutane conversions, isobutene selectivities and yields of the reaction at 823 K for the three tested samples. 

Due to some stability concerns with the N-Cbz group of 8 at high temperatures, compound 25 was used as a model substrate for the reaction. Substrate 25 was irradiated for 2 min (internal temperature reached 185 °C) in a variety of solvents and all thermal reactions reached >95% conversion (Table 6.1). Both aprotic polar solvents (entries 6 and 9) and protic polar solvent (entry 7) gave poor assay yields of product 26. With nonpolar solvents (entry 10) such as o-xylene and xylenes, the rearrangement reaction provided the highest assay yield and proved to be the best solvent choice [9e],... 

Table VIII demonstrates the inverse relationship of conversion to S02 concentration in the feed that is a consequence of applying flow reversal to S02 oxidation using a single reactor. As the S02 concentration in the table moves from 0.8 to over 8 vol%, the conversion drops from 96-97% down to 85%. At the same time, the maximum bed temperature changes from 450 to 610°C. For an equilibrium-limited, exothermic reaction, this behavior is explained by variation of the equilibrium conversion with temperature.

Here, one may employ a higher temperature for the second-stage feed and still achieve the desired conversion level. The conversion and temperature profiles as calculated from equations A and B are given in Table 12.1.2.
