Synthesis and mildew resistance of vinyl acetate and ethyl acrylate films containing chemically anchored fungicides

Synthesis and mildew resistance of vinyl acetate and ethyl acrylate films containing chemically anchored fungicides. Pittman, Charles U., Jr.; Stahl, G. Allan; Winters, Harvey (Dep. Chem., Univ. Alabama, University, Ala., USA). J. Coat. Technol., 50(636), 49-56 (English) 1978. CODEN: JCTEDL. ISSN: 0361-8773. DOCUMENT TYPE: Journal CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 27, 28 Vinyl acetate and Et acrylate polymers contg. 0-5 mol% fungicidal groups I-II gave coatings which resist Aspergillus sp., Alternaria sp., Aureobasidium pullulans, and Pseudomonus sp. The fungicidal coatings were prepd. by copolymg. vinyl acetate or Et acrylate with pentachlorophenyl acrylate (V) [4513-43-3], 8-quinolyl acrylate (VI) [34493-87-3], 2-(phenylaminocarbonyl)phenyl acrylate (VII) [56525-45-2], or 2-(4-thiazolyl)-1-benzimidazolyl acrylate (VIII) [65993-01-3] in bulk with (Me2CCN)2N2 or tert-Bu peroxypivalate as the initiator. The attempted introduction of I-IV groups into vinyl acetate and Et acrylate polymers by treating them with SOCl2 and then with pentachlorophenol (IX) [87-86-5], 8-hydroxyquinoline (X) [148-24-3], salicylanilide (XI) [87-17-2], or 2-(4-thiazolyl)benzimidazole Na salt (XII) [51672-23-2] was unsuccessful because of the extensive hydrolytic polymer degrdn. The fungicidal monomers were prepd. by reacting acryloyl chloride [814-68-6] with IX, X,XI, or XII. Blending IX-XII with vinyl acetate or Et acrylate polymers increased their fungal resistance only temporarily since these biocides were easily leached out.

High-performance liquid chromatographic determination of halogen-substituted salicylanilides

High-performance liquid chromatographic determination of halogen-substituted salicylanilides. Cukor, P.; Persiani, C.; Woehler, M.; Bischak, N. (GTE Lab., Inc., Waltham, Mass., USA). J. Chromatogr., 147, 496-500 (English) 1978. CODEN: JOCRAM. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Brominated salicylanilides were detd. by high-performance liq. chromatog. on Partisil 10-ODS using 254 nm UV detector. The detection limit was 0.005 mg/mL. Irradn. of 3,4',5-tribromosalicylanilide (I) [87-10-5] in alc. with 360 nm light yielded only 4',5-dibromosalicylanilide (II) [87-12-7]. This was contrary to the earlier reports where II in an alc. soln. of higher pH produced 4'-bromosalicylanilide (III) [2627-77-2] upon irradn. However, in alc.-buffer soln. of pH 7.5, all possible degrdn. products, i.e., II, III, and salicylanilide (IV) [87-17-2] were formed.
