As knowledge in chemical kinetics has advanced from the first study of reaction rates by Wilhelmy (1) in 1850, it has become increasingly clear that many reactions take place by a sequence of simple steps, or elementary reactions. This implies…

Native starch has many industrial applications but its use is limited by certain technical difficulties. For example, in paper sizing it is almost impossible to apply the desired amount without making the drying process too slow, because ao much water…

During the past ten years, the importance of the phenomenon of enzymtic adaptation has beoome more and more apparent. Besides being in itself of considerable interest, it possesses implications for general cellular physiology extending outside of the area in which…

The aim of this work was to synthesize the 2,3-dibromo-inden-2-one-1 by the method of Roser; and to study the reaction of this compound with pyridine and with the three methyl-pyridines. Since it was known that the bromine atom in the…
