Actinic light polymerizable coating compositions

Actinic light polymerizable coating compositions. Gruber, Gerald W. (PPG Industries, Inc., USA). U.S. US 4024297 17 May 1977, 12 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: B05D003-06. NCL: 427054000. APPLICATION: US 76-654500 2 Feb 1976. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) A photopolymerizable coating compn. comprised an ethylenically unsatd. org. compd. and an arom. ketone photocataylst. Thus, acrylic acid 275, N,N-dimethylcyclohexylamine 4, 2,6-di-tert-butyl-p-cresol 1.6, and hydroquinone 0.015 part were heated to 100.degree., 500 parts 1,4-butanediol diglycidyl ether was added dropwise over 6 h, and the mixt. was heated 2 h at 100.degree. and cooled to give epoxy diacrylate (I) [63363-87-1]. I (106 parts) and 74 parts TiO2 were ground to form a paste, and 155 parts paste was mixed with 5 parts tributylphosphine. The mixt. (25 parts) and 0.75 part ethyl phenylglyoxylate [1603-79-8] were mixed to give a coating compn. which was applied at 0.008 mm thickness to an Al substrate and passed under 4 UV lamps to give a wrinkle-free dry coating with fair adhesion to the substrate.

Electrochemical investigation on the catalytic effects of metal ions on the redox reactions of a NADH-model compound

Electrochemical investigation on the catalytic effects of metal ions on the redox reactions of a NADH-model compound. Kitani, Akira; Hashimoto, Noboru; Sasaki, Kazuo (Fac. Eng., Hiroshima Univ., Hiroshima, Japan). Nippon Kagaku Kaishi, (8), 1103-8 (Japanese) 1977. CODEN: NKAKB8. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 22, 67 The catalytic effects of Mg2+ and Li+ ions on the reactions of a NADH-model compd. with ketone were studied electrochem. Et benzoylformate (I) [1603-79-8] was used as a model substrate, and 1-benzyl-1,4-dihydronicotinamide (II) [952-92-1] as a NADH-model compd. I exhibits 2 well defined, 1-electron redn. waves in MeCN. In the presence of Mg2+ or Li+, the potentials of these waves shifted towards more pos. values owing to the ion-pair formation between the metal cations and the anionic species produced at the electrode. The anodic peak potential of II shifted towards more pos. values by the addn. of the metal ions. The charge-transfer process involved in the homogeneous redox reactions of II proceeds via a complex like II metal ion-I. The effect of ion-pairing is the main factor in catalytic actions of metal ions.
