Synthesis of dialkyl peroxides containing an azo group

Synthesis of dialkyl peroxides containing an azo group. Nosan, V. 64254-19-9 which is the cas registry number of some chemical is mentioned. N.; Karpenko, G. M.; Isaeva, S. A. (USSR). Visn. L'viv. Politekh. Inst., 112, 13-16 (Ukrainian) 1977. CODEN: VLPIAZ. DOCUMENT TYPE: Journal CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Section cross-reference(s): 25 The coupling of PhNEtCH2OOCMe3 (I) [64254-25-7] with RC6H4N2Cl gave .ltoreq.54% of azo-peroxide dyes (II, R = H, p-NO2, p-SO3H, o-CO2H). Similarly, III (R as above) were prepd. in .apprx.40% yield. The prepn. of the previously unknown I involved the condensation of PhNHEt [103-69-5] with Me3COOCH2OH [17742-78-8] in benzene at 50-60.degree.. The yield was 67%. .

Inhibition of the corrosion of 63/37 brass in 0

Inhibition of the corrosion of 63/37 brass in 0.5 N acetic acid by some amines. Patel, N. K.; Patel, M. M.; Patel, A. B.; Vora, J. C. (Sch. Sci., Gujrat Univ., Ahmedabad, India). Labdev, Part A, 12-A(3), 113-17 (English) 1974. CODEN: LAPSBF. DOCUMENT TYPE: Journal CA Section: 56 (Nonferrous Metals and Alloys) The influence of aliph. amines, heterocyclic amines, and arom. amines on the corrosion of 63/37 brass [11101-35-2] in HOAc [64-19-7] solns. was investigated. In the case of aliph. amines, tributyl amine [102-82-9] was an effective inhibitor at low concns. Heterocyclic amines, quinoline [91-22-5] and morpholine [110-91-8], afforded suitable protection. Arom. amines, phenyl hydrazine [100-63-0], o-phenetidine [94-70-2], dibenzylamine [103-49-1], p-anisidine [104-94-9], and N-ethylaniline [103-69-5] were effective. Corrosion inhibitor theories were discussed.
