Reactions of Chromyl Chloride with Monocarboxylic Acids
ثبت نشده
چکیده
Chromyl chloride was prepared by the literature method 3. A solution of formic acid in carbon tetra chloride was added dropwise to chromyl chloride diluted in the same solvent so that the reaction product was always in excess of formic acid. Since the reaction was violently exothermic, the reaction vessel was maintained at 0 °C throughout the addition. After a few minutes, the colour of the solution changed from red to green with brisk evolution of HC1 gas. On heating under reflux for several hours, a green solid separated out. Different attempts to prepare the same product always gave

Relationship between topological indices and thermodynamic properties and of the monocarboxylic acids applications in QSPR
Topological indices are the numerical value associated with chemical constitution purporting for correlation of chemical structure with various physical properties, chemical reactivity or biological activity. Graph theory is a delightful playground for the exploration of proof techniques in Discrete Mathematics and its results have applications in many areas of sciences. One of the useful indic...
متن کاملApplication of Graph Theory: Relationship of Topological Indices with the Partition Coefficient (logP) of the Monocarboxylic Acids
It is well known that the chemical behavior of a compound is dependent upon the structure of itsmolecules. Quantitative structure – activity relationship (QSAR) studies and quantitative structure –property relationship (QSPR) studies are active areas of chemical research that focus on the nature ofthis dependency. Topological indices are the numerical value associated with chemical constitution...

متن کاملHighly spin-polarized chromium dioxide thin films prepared by chemical vapor deposition from chromyl chloride
Highly spin-polarized chromium dioxide (CrO2) thin films were deposited on ~100! TiO2 substrates by chemical vapor deposition using chromyl chloride as a precursor. The spin polarization, as measured by the point contact Andreev reflection technique, was 8163%. X-ray diffraction u/2u scans indicated the films grew completely ~100! oriented, in registry with the ~100! oriented TiO2 substrate. X-...
متن کاملBranched Chain Amino Acid Aminotransferase
The kinetics of transamination reactions catalyzed by pig heart “branched chain amino acid” aminotransferase was investigated. The activation of aged preparations by 2mercaptoethanol, previously noted, was associated with increases in both the maximum velocity and enzyme-substrate affinities. This implies a protein conformational change. The sharp pH optimum observed with standard assay conditi...
