摘要:

AbstractThe data ofBuchner and Kleijnon the flocculation of agar have been employed to calculate the lyotropic numbers of the formate and acetate ions. Hydration heats of the ions, comparable to those ofLatimer, Pitzer and Slansky, have been derived from the lyotropic numbers. Other magnitudes, which have been obtained, include lattice energies and standard enthalpies of formation of formates and acetates.Estimates of the standard enthalpies of formation of the formate and acetate radicals are quoted, and values for the electron affinities of the radicals are given.

摘要:

AbstractThe reaction of PSCl3, with alkylmagnesium halides has been studied. In the case of methyl‐, ethyl‐, propyl‐, butyl‐ andisobutyl‐magnesium halides compounds with formula (R2PS)2, were formed. Their infrared spectra were recorded from 400 cm−1to 3000 cm−1. From these spectra it was concluded that bi(dialkylphosphinothioyl) compounds were formed.In most cases a number of by‐products were isolated and some of these

AbstractMeasurements are described on the e.m.f. of cells with electrodes of paraffin and polystyrene membranes of different composition in a number of solutions containing uni‐ or higher valenced cations. From these researches it follows that uni‐ and higher valenced cations behave antagonistica

摘要:

AbstractPhenanthrene reacts quickly with one mole of ozone at the 9,10‐double bond. In chloroform a polymeric mono‐ozonide (II) is obtained, which can be converted into diphenic acid. In methanol the reaction takes a different course resulting in the formation of a cyclic methoxy‐hydroxy‐peroxide (V) and a cyclic dimethoxy‐pero

摘要:

AbstractThe infra‐red absorption spectra of a number of phosphorus acid esters have been measured. The assignment of a number of frequencies is discussed. A shift in the phosphoryl stretching vibration to higher frequency is observed in “energy‐rich” phosphorus acid

摘要:

AbstractMolecular‐orbital calculations of structural static parameters (bond orders, π‐electron densities and free valences) and dynamic indices (atom,ortho‐ andpara‐localization energies) are presented for a number of naphthindoles. The results are used to predict the chemical properties of the molecules. We have made a comparison of the carcinogenic inactivity and the static and dynamic complex indices used to characterize the K region in some benzindoles and these napht
