Mathur, J. N. published the artcileThermodynamics of americium(3+)-substituted pyrazolone-crown ether adducts<\/i><\/b>, COA of Formula: C12H9F3N2O2<\/a>, the main research area is americium pyrazolone crown ether adduct.<\/p>\n

The thermodn. parameters for the extraction of Am3+ with pyrazolones (HA = HPMBP or HPMTFP) alone as well as their mixtures with one of the crown ethers B15C5 or DCH18C6 were calculated in chloroform at 30\u00b0 by using the temperature coefficient method. The self-adduct species Am(A)3.HA is enthalpy stabilized. The adduct species Am(A)3.HA.DCH18C6 are stabilized by entropy and opposed by enthalpy. The adduct species Am(A)3.HA.B15C5 (HA = HPMBP) and Am(A)3.B15C5 or Am(A)3.2B15C5 (HA = HPMTFP) are stabilized by enthalpy. These data were correlated with the difference in the nature of binding of the two crown ethers with Am3+.<\/p>\n

Solvent Extraction and Ion Exchange published new progress about Complexation enthalpy. 1691-93-6 belongs to class pyrazoles-derivatives, name is 5-Methyl-2-phenyl-4-(2,2,2-trifluoroacetyl)-1H-pyrazol-3(2H)-one, and the molecular formula is C12H9F3N2O2, COA of Formula: C12H9F3N2O2<\/a>.<\/p>\n
