Benz[a]acephenanthrylene, also known as 1,2-dihydro-1,2,3,4,7,8,9,10-octahydrobenzo[a]acenaphthylene, is a polycyclic aromatic hydrocarbon (PAH) consisting of a benzene ring fused to an acenaphthene core. It is a colorless solid with a molecular formula of C20H14 and a molecular weight of 254.32 g/mol. Benz[a]acephenanthrylene is formed during the incomplete combustion of organic materials, such as coal, oil, and tobacco, and is considered a potential environmental pollutant due to its toxic and carcinogenic properties. Benz[a]acephenanthrylene is also found in various industrial processes and has been identified as a component of some coal tar pitches and petroleum products. Due to its persistence in the environment and potential health risks, it is important to monitor and control the release of this chemical into the environment.

192-28-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 192-28-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,9 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 192-28:
(5*1)+(4*9)+(3*2)+(2*2)+(1*8)=59
59 % 10 = 9
So 192-28-9 is a valid CAS Registry Number.

Probing mechanisms of aryl-aryl bond cleavages under flash vacuum pyrolysis conditions

Jackson, Edward A.,Xue, Xiang,Cho, Hee Yeon,Scott, Lawrence T.

, p. 1279 - 1287 (2014/11/08)

Several biaryls have been subjected to flash vacuum pyrolysis (FVP) at 1100°C and 0.8-0.9hPa. Product compositions are reported for the FVP of 9-phenylanthracene (1), 2-bromobiphenyl (5), biphenyl (8), 1,10- diphenylanthracene (12), 9-(2-naphthyl)anthracene (17), and 9,9′- bianthracenyl (20). The experimental results have been used to evaluate four possible mechanistic pathways for the cleavage of aryl-aryl bonds under these conditions: (1) the 'explosion' of substituted phenyl radicals; (2) hydrogen atom attachment to an ipso-carbon atom of the biaryl followed by C-C bond cleavage; (3) direct homolysis; and (4) loss of a fragment as an aryne. None of these mechanisms by itself successfully accommodates all of the experimental facts. The data suggest that aryl-aryl bond cleavages under FVP conditions involve at least two different mechanistic pathways and that the relative contributions of the competing pathways probably vary from one biaryl to the next.
