2-Naphthalenethiol is an organosulfur compound with the formula C 10 H 7 SH. It is a white solid. It is a white solid. It is one of two mono thiols of naphthalene , the other being 1-naphthalenethiol .
[1] 1-Naphthalenethiol can also be prepared from 1-bromonaphthalene by Pd-catalyzed reaction with the silylthiolate i Pr 3 SiSK followed by hydrolysis of the silathioether. [2] It was first prepared from the Grignard reagent generated from 1-bromonaphthalene. Treatment of that reagent with elemental sulfur followed by acidification gave the ...
It gets 4.7 stars at Walmart, Target and Amazon. ... At Walmart, where it earned a 4.4-star rating, it’s on sale for $99, down from $110, for 10% savings. The same printer sells for $171 at Amazon.
Traditionally, 2-naphthol is produced by a two-step process that begins with the sulfonation of naphthalene in sulfuric acid: [2] C 10 H 8 + H 2 SO 4 → C 10 H 7 SO 3 H + H 2 O. The sulfonic acid group is then cleaved in molten sodium hydroxide: C 10 H 7 (SO 3 H) + 3 NaOH → C 10 H 7 ONa + Na 2 SO 3 + 2 H 2 O. Neutralization of the product ...
Aminonaphthalenesulfonic acids are compounds with the composition C 10 H 6 (NH 2)(SO 3 H), being derived from naphthalene (C 10 H 8) substituted by an amino and sulfonic acid groups. These compounds are colorless solids.
It was first prepared by Robert Evert and Victor Merz in 1876 by hydrolysis of 2,6-dicyanonaphthalene. [2] [3] 1,8-Naphthalenedicarboxylic acid can be isomerized to 2,6-naphthalenedicarboxylic acid via the intermediacy of the dipotassium dicarboxylates. [2] It is also produced by oxidation of 2,6-diisopropylnaphthalene. [4]
1-Naphthol, or α-naphthol, is an organic compound with the formula C 10 H 7 OH.It is a fluorescent white solid. 1-Naphthol differs from its isomer 2-naphthol by the location of the hydroxyl group on the naphthalene ring.
2-Naphthylamine or 2-aminonaphthalene is one of two isomeric aminonaphthalenes, compounds with the formula C 10 H 7 NH 2. It is a colorless solid, but samples take on a reddish color in air because of oxidation. It was formerly used to make azo dyes, but it is a known carcinogen and has largely been replaced by less toxic compounds. [2]
