DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 75 Two new coordination polymers, [Zn(bpndc)(4,4'-bpy)1.5]n×0.5n(4,4'-bpy)×0.5nH2O (1) and [Zn(bpndc)(phen)(H2O)]n (2) (H2bpndc = benzophenone-4,4'-dicarboxylic acid; 4,4'-bpy = 4,4'-bipyridine; phen = 1,10-phenanthroline) were synthesized by the hydrothermal reactions and characterized by single crystal x-ray diffraction, elemental anal., IR spectrum and thermal anal. 964-68-1 and 820967-28-0 are also in the experiment. In 1, 4,4'-bpy mols. link Zn(II) ions into 1-dimensional ladders, and these ladders are bridged by bpndc2- ligands, resulting in an infinite two-dimensional rhombohedral network. Such rhombohedral grids interweave each other, forming a three-dimensional structure. In 2, Zn2O2 cores are interconnected by bpndc2- ligands to generate a 1-dimensional centripede-like double-chain structure, and further assembled by O-H×××O H bonds and p-p stacking interactions to form three-dimensional supramol. network with 1-dimensional channels. .

Synthesis of aromatic dicarboxylic acids and their use as corrosion inhibitors for zinc coatings

Synthesis of aromatic dicarboxylic acids and their use as corrosion inhibitors for zinc coatings. Dorofeev, V. T.; Volkov, I. V.; Fedorkova, O. P.; Shugurova, L. N.Some commonly used reagents like 964-68-1 and 83210-85-9 are used in this experiment. (USSR). Vopr. Khim. Khim. Tekhnol., 77, 90-3 (Russian) 1985. CODEN: VKKCAJ. ISSN: 0321-4095.

Co(OAc)2-KBr gave 90% R2CHCCl3 (I; R = 4-HO2CC6H4). Dehydrochlorinating I gave 97% R2C:CCl2 (II; same R). R2CH2, R2CO, and R2C:CH2 were prepd. from II in 92-95% yields. The 5 acids were effective corrosion inhibitors in Zn coatings formed by electrodeposition on steel. Stationary corrosion currents of 2.78-9.54 ′ 10-2 A/m2 were obsd. .
