摘要:

A chronopotentiometric study of the reaction Pu(III) → Pu(IV) + e−in molten LiCl-KCl eutectic is reported. The diffusion coefficient DPu(III)increased from 4.8.10−6to 27.6.10−6cm2sec−1when the temperature was raised from 400 to 650°C.

摘要:

Direct potentiometry in cells without liquid junction was used to study solutions of six acids in tetramethylene sulfone. The hydrogen electrode was found to be reversible and gave reproducible potentials in this solventvs. a silver-silver chloride reference electrode. Titrations of the acids were accomplished with these same electrodes.

摘要:

The complexes MeY2Hn(3-n)-formed between trivalent lanthanides and HEDTA are studied with the idea of determining their stability constants and their degree of protonation.

摘要:

Highly hindered hydroxyl groups in steroids (17α-ol groups in steroids with a 17α, 20α, 21- or 17α,20β,21-triol structure) maybe converted to TMSi ether groups by reaction with N-trimethylsilylimidazole, alone or in combination withbis-trimethylsilylacetamide and with or without trimethylchlorosilane as a catalyst. At or above 150°C, the rates of catalyzed and non-catalyzed silylation reactions with these reagents are s imilar.

摘要:

A new extraction-photometric method is suggested for the determination of microgram amounts of some thiols. The method is based on the reaction of thiol with p-dimethyl- or p-diethylaminophenyl-mercuric acetate, followed by a subsequent photometric determination of the excess mercurorganic reagent after extraction by diphenyl-carbazone into benzene. Five 200 μg amounts of thiol are determinable with a relative error of 4–8%.
