As early as 1957, the Metropolitan Life Insurance Company published a chart showing that as blood pressure levels rose, life expectancy fell. Conversely, the lower the levels, the longer the life. And who doesn t want a long, healthy life ... 

Both at 70 and 80 °C, selectivity starts to decrease above 60% conversion, but more rapidly at 80 °C (product yield at 95% conversion <60% at 80 C >75% yield at 70 °C). Selectivity loss at higher conversions can be explained by competing addition of coproduced water instead of methanol to the 3-methoxyacrylate intermediate. In contrast to the stable 3,3-dimethoxy methyl propionate acetal product formed by methanol addition, the hemiacetal 3-methoxy-3-hydroxy methyl propionate generated by addition of water is prone to overoxidation, especially at higher reaction temperatures. Consequently, 3,3-dimethoxy methyl propionate selectivity benefits from increasing the methanol/methyl acrylate ratio. The results of variation of methanol/methyl acrylate ratio on activity and selectivity are depicted in Chart 11.2c,d, respectively (Pd/Cu/Fe/methyl acrylate 1/500/500/25000 oxygen pressure 0.2 MPa). Whereas conversion rates are equal at different methanol/methyl acrylate ratios, 3,3-dimethoxy methyl propionate selectivity erodes to 50% above 90% conversion at a low methanol/methyl acrylate... 

Chart 11.3 compares experimental with simulated substrate conversion and product formation using a Pd/Cu/Fe/methyl acrylate ratio of 1/500/500/25000 at 70 °C and oxygen pressure of 0.2 MPa at a methanol/methyl acrylate ratio of... 

Convert the 14.7 psia EFV curves to the pressures which have been set for the furnace outlet and the entrance to the fla zone. This latter value is, for all practical purposes, equal to the flash zone pressure. The vapor pressure charts and nomographs in Section 4 of Maxwell are useful for these conversions. 

The equilibrium vapor pressure of water over a solution containing the equivalent of 20% potassium carbonate as a function of conversion to bicarbonate is shown in Figure 5 10. This chart is also based on data obtained by Tosh et al. (1959). Here, again, there is not much difference in the vapor pressure of water for 20 and 30% equivalent potassium carbonate concentrations. 

We see that in this case the nonideal gas behavior increases the fractional conversion, because the product behaves less like an ideal gas than do the reactants. The effect is small, but significant (34.5 vs. 31.6 mol% NH3 in the equilibrium gas). This same calculation has been carried out for a variety of temperatures and pressures the results are summarized in Figure 12.10. The reader may verify that (within chart-...
