An equation-of-state (EoS) scheme to correlate the solubility of solids in supercritical fluids is presented. The solute fugacity coefficient obtained using pure-solvent compressibility factor, and empirical solute-to-solvent parameter ratios cohesion factors covolumes. proposed method simpler than conventional EoS calculations since no iteration required. We retain link classical cubic mixing ...

Invertase inhibitors have been isolated and partially purified from red beets, sugar beets, and sweet potatoes. These inhibitors are thermolabile proteins with molecular weights of 18,000 to 23,000. They do not inhibit yeast and Neurospora invertases, but they are reactive with potato tuber invertase and other plant invertases with pH optima near 4.5. There are differences in reactivity of the ...
