Significance dropping point

Scheme 13.3 reveals how much material is lost during the entire resolution process. The resolution has an overall yield of 39%. The number 39% might seem low, but remember that half of the material that enters a resolution is the undesired enantiomer. A 39% yield in a resolution corresponds to a recovery of 78% of the desired enantiomer. Note that the various transformations in Scheme 13.3 are typically very efficient. Based on the number of moles of material at each point in the process, only the resolution step has a significant drop. 

During the above described milling process a separate pile of approximately 4,000 kg. was used for our study. Temperatures in different points of the pile were measured periodically. A significant drop in this variable was the setting moment to further aerate the pile by mechanical means. 

The impact of the use of computing and software on the marks is not clear. In fact, the marks monitoring revealed a very significant drop of the marks from the first project to the second one (for SMI). Another important difference was the marks obtained in Project 4. Some reasons can be pointed out to explain these differences, namely (Pinho-Lopes et al., 2011) ... 

A continuous process for the production of high dropping point lithium complex greases has been developed (13). Here, the conventional dibasic acid salt or the dibasic ester component is no longer used. These conventional components are substituted with a borated additive fed into the reactor downstream of the thickener formation zone. This substitution and process modification results in a significantly less problematic process and a substantial increase in production throughput (13). 

Also, it can be seen that properties such as density and dynamic viscosity undergo a significant drop (near the critical point this drop is almost vertical) within a very narrow temperature range (see Figs. A3.5(b) and A3.7(b), respectively, for water, and Figs. A3.14 and A3.16 for carbon dioxide), while the kinematic viscosity and specific... 

Black oils are a common category of reservoir fluids, and are similar to volatile oils in behaviour, except that they contain a lower fraction of volatile components and therefore require a much larger pressure drop below the bubble point before significant volumes of gas are released from solution. This is reflected by the position of the iso-vol lines in the phase diagram, where the lines of low liquid percentage are grouped around the dew point line.
