Agreement with United States

The protonation constants of ligand 24 and 25 were determined by Arena and coll. [34], who reevaluated the literature pKa values of compound 24 [35] because they were not in agreement with solid state evidences [33]. Only two titrable protons were found in the pH region 2.5-11.0 and the proton formation constants determined (Log K = 3.34 and 11.5) rule out the existence of a "super acidic proton" (pKa < 1) for compound 24 [35]. However, this proton is much more acidic (5.3 log units) than the monomeric... 

Illinois Power and Waste Recovery, Inc. (WRI), the largest producer of IDE in the United States, entered into an agreement under which WRI will supply I DE to Illinois Power s Baldwin station. Beginning in late 1994, about 3% of the coal was replaced with tires. This requires 70,000 tons of I DE per year, or the equivalent of seven million passenger tires, and represents - 60% of the scrap tires generated in Illinois each year. 

The preceding orbital phase predictions of some topological units (like 1, 4-6) can be easily extended to more complex cychc diradicals [29], as shown in Fig. 12. On the basis of TMM sub-structure (1), diradicals 8-11 are predicted to be phase continuous in their triplet states. Such a triplet preference in their ground states is in agreement with calculation results and available experiments, as listed in Table...
