Granulates containing metal chelate complexes

Granulates containing metal chelate complexes. Jungbauer, Anton; Raubenheimer, Hans Juergen; Leutner, Bernd; Perner, Johannes (BASF A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3325059 A1 24 Jan 1985, 13 pp. (German). (Germany). CODEN: GWXXBX. CLASS: ICM: C09K003-00. ICS: B01J002-04; B01J002-28; A01N037-44; A61L009-01; C05D009-02; C11D003-33. APPLICATION: DE 83-3325059 12 Jul 1983. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Section cross-reference(s): 45 An EDTA complex contg. alkali metal, ammonium, or Mg ions and Zn2+, Cu2+, Mn2+, Fe3+, or Co3+ is granulated with a binder comprising solid polyethylene glycol [25322-68-3], a paraffin, ethoxylated fatty alcs., or a fatty acid. The granules have low hygroscopicity, are dust free, and are useful in detergent compns., etc. Thus, 100 kg spray-dried EDTA di-Na Cu salt [14025-15-1] (as the dihydrate) was added to 100 kg ethoxylated (d.p. 50) fatty alcs. (m. 50°) at 100°, and the mixt. was granulated. The powd. mixt. had good resistance to agglomeration, absorbed 1.2% H2O during 24 h at 65% relative humidity, and had good soly. in water.

Chemical defoliation of nursery stock using chelated forms of copper and iron

Chemical defoliation of nursery stock using chelated forms of copper and iron. Knight, J. N. (East Malling Res. Stn.Chemicals with cas numbers 32991-48-3 and 7758-98-7 also play role., Maidstone/Kent ME19 6BJ, UK). J. Hortic. Sci., 58(4), 471-6 (English) 1983. CODEN: JHSCA8. ISSN: 0022-1589. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Shoots of maiden cv Cox's Orange Pippin apple trees, M.9 and MM.106 apple rootstocks, cv Pixy plum and Colt cherry rootstocks were effectively defoliated by CuEDTA [14025-15-1], whereas Quince A rootstock responded slowly. Tips of M.9 were slightly damaged by Cu treatment. A possible mode of action and interaction with endogenous factors are discussed. Treatment with WK [54992-17-5] surfactant, ethephon [16672-87-0] or phenylthiadiazolyl thioacetate (NC9634) [32991-48-3] in combination with CuEDTA generally failed to enhance the effect of CuEDTA alone. .
