Nucleophilic substitution reactions on 3-bromo- and 3-nitrobenzanthrones: Nucleophilic substitution reactions on 3-bromo- and 3-nitrobenzanthrones. Vaidyanathan, T.; Seshadri, S. (Dyes Res. Lab., Univ. Dep. Chem. Technol., Bombay 400019, India). Dyes Pigm., 5(6), 431-6 (English) 1984. CODEN: DYPIDX. ISSN: 0143-7208. DOCUMENT TYPE: Journal CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 25 Reaction of 3-bromobenzanthrone [81-96-9] with different arylamines gave rise to 6-(arylamino)-3-bromobenzanthrones. Anomalous behavior was obsd. with 2-aminobenzothiazole [136-95-8], when the Br atom underwent displacement, and with thiourea [62-56-6], when 3-mercaptobenzanthrone [6409-45-6] was obtained. Reactions of 3-nitrobenzanthrone [17117-34-9], on the other hand, gave rise to 4-substituted amino derivs.

Benzothiazole derivatives as inhibitors of corrosion of steel St3 in hydrochloric acid: Benzothiazole derivatives as inhibitors of corrosion of steel St3 in hydrochloric acid. Makovei, G. L.; Ushakov, V. G.; Aleinik, R. L.; Pushkareva, V. V.; Koroleva, V. R.; Tolmachev, A. A. (Kiev. Politekh. Inst., Kiev, USSR). Zashch. Met., 23(1), 142-7 (Russian) 1987. CODEN: ZAMEA9. ISSN: 0044-1856. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 71 As part of an on-going study, the inhibiting effects on steel St3 in HCl of 2-aminobenzothiazole (I) [136-95-8], 2-methylbenzothiazole (II) [120-75-2], and 2-methyl-5-aminobenzothiazole (III) [13382-43-9], as well as the effect on the protective properties of I of g-rays from 60Co in the absorbed dose range up to 10 MGy were studied. Tests were made to relate the mechanism of H evolution and anodic ionization of Fe to the distribution of p-electron d. on reaction centers of the mols. The following characteristics of the inhibiting action of the above compds. were studied: corrosion rate, protective effect, polarization resistance, characteristics of cathodic H evolution and anodic Fe ionization, and the effective activation energy of the corrosion process.
