Purification Methods
Fractionally distil 1-nitronaphthalene under reduced pressure, then crystallise it from EtOH, aqueous EtOH or heptane. Chromatograph it on alumina with *benzene/pet ether as eluent. It sublimes in vacuo. The 1:1 picrate complex has m 72o (from EtOH). [Beilstein 5 H 553, 5 III 1593, 5 IV 1673.]
Check Digit Verification of cas no
The CAS Registry Mumber 86-57-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 86-57:
(4*8)+(3*6)+(2*5)+(1*7)=67
67 % 10 = 7
So 86-57-7 is a valid CAS Registry Number.

Microwave-induced surface-mediated highly efficient regioselective nitration of aromatic compounds: Effects of penetration depth
BANIK, BIMAL K.,DAS, APARNA,YADAV, RAM NARESH
, p. 2203 - 2206 (2021/08/24)
Surface mediated highly regioselective nitration of aromatic compounds under diverse microwave-induced conditions was investigated in this work. The effects of the penetration depth of the surfaces were found to be more crucial than other dielectric parameters. Despite significant progress of microwave-induced reactions, no reports have examined the penetration depth of the surfaces used in these processes.

The ipso nitration of aryl boronic acid derivatives has been developed using fuming nitric acid as the nitrating agent. This facile procedure provides efficient and chemoselective access to a variety of aromatic nitro compounds. While several activating agents and nitro sources have been reported in the literature for this synthetically useful transformation, this report demonstrates that these processes likely generate a common active reagent, anhydrous HNO3. Kinetic and mechanistic studies have revealed that the reaction order in HNO3 is >2 and indicate that the ?NO2 radical is the active species.
