Markov, P.; Rumyan, K.; Chorbadzhiev, S. (Dep. Org. Chem., Univ. Sofia, Sofia, Bulg.). God. Sofii. Univ., Khim. Fak., Volume Date 1975-1976, 70, Pt. 1, 51-8 (English) 1978. CODEN: GSKFAL. ISSN: 0584-0317. DOCUMENT TYPE: Journal CA Section: 55 (Ferrous Metals and Alloys) The corrosion of Fe was studied by 2.529 N H2SO4, 0.532 N HCl, or 1.94 N H3BO3 solns. at 20, 40, and 60° for 6 and 8 h and the inhibition efficiencies of some arom. and arylaliph. sulfides were detd. by gravimetry. The org. sulfides studied showed less inhibition than the aliph. sulfides and mercaptans with ~60-80% inhibition. With increasing temp. the inhibition efficiency of org. sulfides decreased except for H3BO3 solns. dibenzyl monosulfide [538-74-9], bis(o-nitrophenyl)disulfide [1155-00-6], and bis(p-nitrophenyl)monosulfide (I) [1223-31-0] had good inhibition in H2SO4, I and bis(p-nitrophenyl)disulfide [100-32-3] were good inhibitors in HCl solns. whereas the addn. of org. sulfide increased the Fe corrosion in H3BO3 soln.

CODEN: JKXXAF.There are some reagents with their cas registry numbers 1223-31-0 and 86317-68-2 are used in this study. CLASS: IC: C07C113-04; C07C135-00; C07C149-433; C07C161-00. ICA: C09K003-34. APPLICATION: JP 82-83773 18 May 1982. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Nineteen azoxy and azo compds. Z[N(O):NQR]2 [Z = phenylene, C6H4Z1C6H4 (Z1 = O, S, CH2); Q = phenylene; R = alkyl, alkoxy], RQN:N(O)ZN:NQR, Z(N:NQR)2, and RQN:N(0)QCHO were prepd. by, e.g., reaction of Z(NO2)2 with RQN(MgX)2 (X = halo). Thus, addn. of 4-MeC6H4NH2 in THF to EtMgBr in THF with ice cooling under N and stirring 30 min at 50° formed 4-MeC6H4N(MgBr)2 (in THF). To this (15.9 mmol) was added 3 mmol 4-O2NC6H4SC6H4NO2-4 with ice cooling and reaction 3 h at 55° gave I 29, II 30, and III 3%. .
