17082-12-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17082-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,8 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17082-12:
(7*1)+(6*7)+(5*0)+(4*8)+(3*2)+(2*1)+(1*2)=91
91 % 10 = 1
So 17082-12-1 is a valid CAS Registry Number.

Evolution of Photooxidation Products upon Irradiation of Phenyl Azide in the Presence of Molecular Oxygen

Go, Celia Lee,Waddell, Walter H.

, p. 2897 - 2900 (1983)

The reaction of phenylnitrene with oxygen was reinvestigated by irradiating phenyl azide (1) in O2-saturated acetonitrile solutions.Quantum yields of the disappearance of 1 are calculated from absorption spectral changes, and primary photoproducts are determined by using high-pressure liquid chromatography.The photochemistry of the reaction products (azobenzene, azoxybenzene, nitrobenzene, and nitrosobenzene) are also examined, including measurements of quantum yields and determinations of primary photoproducts and product ratios.A reaction sequence is presented to account for the photooxidation products afforded upon irradiation of 1 in the presence of oxygen.The reaction of phenylnitrene with oxygen is an effective termination step in the autocatalytic chain decomposition of 1.

Carbon Dioxide-promoted Electrochemical Reduction of Aromatic Nitro Compounds to Azoxy Compounds in Acetonitrile

CO2 was found to promote electrochemical reduction of aromatic nitro compounds in acetonitrile even in the absence of a proton source to produce multi-electron reduction products, azoxy compounds as well as smaller amounts of azo and hydroxylamino compounds.

Dual behavior of ZSM-5 as bronsted acid and electron acceptor in the adsorption of N,N'-diphenylhydrazine

Marti, Vicente,Fornes, Vicente,Garcia, Hermenegildo,Roth, Heinz Dieter

, p. 473 - 477 (2000)

Incorporation of N,N'-diphenylhydrazine into HZSM-5 led to the formation of azobenzene and aniline (70-80 mol-% mass balance). The formation of azobenzene can be followed by the appearance in diffuse reflectance UV/Vis spectroscopy of a characteristic band (λmax = 420 nm). IR spectra of the extracted solids indicate that some aniline is retained in the zeolite, probably due to acid-base interaction with active sites. The products are rationalized by two competing mechanisms: the formation of azobenzene by electron transfer to an oxidizing site, the generation of aniline by proton transfer from a Bronsted acid site. A long-wavelength diffuse-reflectance band (λmax = 800 nm) in the initial stages of the reaction supports the intermediacy of a radical cation. These results show that acid zeolites can exhibit a dual behavior against basic substrates with low oxidation potential, serving simultaneously as electron acceptor and Bronsted acid.

Modification of photochemical reactivity by nafion. Photocyclization and photochemical cis-trans isomerization of azobenzene

Tung, Chen-Ho,Guan, Jing-Qu

, p. 9417 - 9421 (1996)

The photophysical and photochemical behavior of azobenzene (AB) incorporated into solvent-swollen acid form Nafion (Nafion-H+) membranes were examined. In water-swollen Nafion-H+ membrane AB exhibits strong fluorescence at room temperature, which has never been observed in isotropic solvents. Photolysis of AB adsorbed in water-swollen Nafion-H+ results in its cyclization to give benzo[c]cinnoline (BC) and benzidine (BZ) in quantitative yield. The product distribution is very dependent upon the number of AB molecules in each water cluster of the Nafion membrane (occupancy number). In the case of the occupancy number greater than 2, BC and BZ are formed equimolarly, while when only one AB molecule exists in each water cluster, BC is exclusively produced. The AB molecules incorporated into methanol-swollen Nafion-H+ membrane do not emit fluorescence and only undergo cis-trans isomerization when they are photoirradiated. These observations suggest that in water-swollen Nafion-H+ AB molecules are solublized in the fluorocarbon/water interface, and the protons of the Nafion-H+ participate in the photochemical and photophysical processes of AB. On the other hand, in methanol-swollen Nafion-H+ membrane AB molecules are located in the methanol pools, and their photochemical and photophysical behaviors are not intervened by the Nafion protons.

Mechanism of thermal isomerization of azobenzene in zeolite cavities

Kuriyama, Yasunao,Oishi, Shigero

The life time of cis-azobenzene in zeolite supercage is twenty times longer than that in benzene at room temperature. The kinetic studies indicate that the thermal isomerization proceeds through inversion mechanism. Activation parameters show that the zeo
