On the Electrolytic Rectification Effect in Ion-exchange Membranes
Bulletin of the Chemical Society of Japan - Tập 37 Số 5 - Trang 668-671 - 1964
Manabu Sen o, Takeo Yamabe
Abstract The electrolytic rectification effect has been observed in a double-membrane system. The static and dynamic current-voltage characteristics have been measured, and it has been demonstrated that the mechanism of the rectification similar to that of the p-n semiconductor junction holds true for this system. Reasonable values have been estimate...... hiện toàn bộ
Hydrogen Bonding Effect on the Fluorescence of π-Electron System. III. Fluorescence Quenching of Some Nitrogen Heterocycles Caused by Hydrogen Bond Formation
Bulletin of the Chemical Society of Japan - Tập 30 Số 7 - Trang 711-715 - 1957
Noboru Mataga, Shizuyo Tsuno
Abstract 1. Hydrogen bonding effect on the fluorescence of acridine, 3,6-diaminoacridine and 3,6-bisdimethylaminoacridine was studied in non-polar solvent added with proton donors such as phenol, naphthols, aniline and pyrrole. 2. Their fluorescence yields are decreased when hydrogen bonded with these proton donors, in...... hiện toàn bộ
Aggregation Effects on Electrochemical and Spectroelectrochemical Properties of [2,3,9,10,16,17,23,24-Octa(3,3-dimethyl-1-butynyl)phthalocyaninato]cobalt(II) Complex
Bulletin of the Chemical Society of Japan - Tập 71 Số 5 - Trang 1039-1047 - 1998
Hiroaki Isago, Clifford C. Leznoff, Matthew F. Ryan, Robert A. Metcalfe, Rifka Davids, A. B. P. Lever
Abstract The title complex, [Co(odmbpc)], which is a single isomer and is highly soluble in common organic solvents, has been prepared and investigated electrochemically and spectroelectrochemically in dichloromethane solutions. The cyclic voltammograms of this complex at a concentration of ca. 6 × 10−5 mol dm−3 exhibited two reversible reduction wav...... hiện toàn bộ
Oxidation of Propylene over the Tin-Antimony Oxide Catalysts. I. Dependency of Acrolein Formation on the Composition of Catalyst and Calcination Conditions
Bulletin of the Chemical Society of Japan - Tập 40 Số 9 - Trang 2172-2176 - 1967
Katsuhiko Wakabayashi, Yoshio Kamiya, Nobuto Ohta
Abstract For the purpose of elucidating the catalysis of the binary system consisting of Sn and Sb oxides, recommended in the patent for the oxidation of propylene to acrolein, the oxidation of propylene has been studied; in addition, the X-ray patterns of the system have been investigated. The mixtures of this binary system after sintering were diff...... hiện toàn bộ
Oxidation of Propylene over the Tin-Antimony Oxide Catalysts. II. Investigations of Physicochemical Properties of the Catalysts
Bulletin of the Chemical Society of Japan - Tập 41 Số 11 - Trang 2776-2781 - 1968
Katsuhiko Wakabayashi, Yoshio Kamiya, Nobuto Ohta
Abstract The physicochemical properties of the binary system composed of Sn and Sb oxides have been investigated. The electrical conductivity increased rapidly up to 3 atom% Sb, and subsequently decreased, little by little, as the Sb oxide content in the binary system increased. The surface area also increased rapidly up to 3 atom% Sb, and in the reg...... hiện toàn bộ
A Priori Assessment of the Maximum Possible Entrainment Effect Attainable during Preferential Crystallization. The Case of the Simultaneous Resolution of (±)-Ephedrine and (±)-Mandelic Acid
Bulletin of the Chemical Society of Japan - Tập 77 Số 1 - Trang 79-86 - 2004
Fabrice Dufour, Guy Perez, Gérard Coquerel
Abstract The strong link observed between the detection of unstable or metastable racemic compounds in the systems studied and the maximum entrainment effect attainable during preferential crystallization (PC) (assessed by the maximum value of the enantiomeric excess of the mother solution at the end of PC (eefmax)) is confirmed by the results obtain...... hiện toàn bộ
Syntheses and Properties of Some Thio Derivatives of Acetylacetonato-nickel(II)
Bulletin of the Chemical Society of Japan - Tập 40 Số 12 - Trang 2819-2822 - 1967
Akira Ouchi, Mitsutoshi Hyodo, Yoshiaki Takahashi
Abstract Derivatives of acetylacetonato-nickel(II) in which the coordinating oxygen is replaced by sulfur to various extents have been isolated by the reaction between nickel(II) acetylacetonate and hydrogen sulfide in an ethanolic solution, using hydrogen chloride as the catalyst. These compounds are soluble in organic solvents, such as benzene, ace...... hiện toàn bộ
Polarized Absorption and Reflection Spectra of the Single Crystals of Benzidine–7,7,8,8-Tetracyano-p-quinodimethane Molecular Complexes
Bulletin of the Chemical Society of Japan - Tập 52 Số 11 - Trang 3180-3191 - 1979
Kyuya Yakushi, Masaaki Iguchi, Haruo Kuroda
Abstract Polarized absorption and reflection spectra were observed on the single crystals of the solventfree and solvent containing modifications of benzidine (BD)–7,7,8,8-tetracyano-p-quinodimethane (TCNQ) molecular complex, by using the microspectrophotometers of transmission and reflection types. The absorption spectra obtained by the dispersion a...... hiện toàn bộ
A Semi-empirical MO Study of Radical-induced Decomposition of Dibenzoyl Peroxide. The Charge-transfer Character and Reaction Mechanism
Bulletin of the Chemical Society of Japan - Tập 52 Số 4 - Trang 1086-1090 - 1979
Osamu Kikuchi, Keizô Suzuki, Katsumi Tokumaru
Abstract Radical-induced decomposition reactions of diacyl peroxides were investigated on the basis of the electronic structure of the peroxide-radical systems which were calculated using an approximate restricted open-shell SCF MO method in the MINDO/3 approximation, and on the basis of configuration analysis of the transition state of the reaction....... hiện toàn bộ
