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 .
The UOP characterisation factor (K w) (UOP 375-07 [2]), is based on the observation that the specific gravities of the hydrocarbons are related to their H/C ratio (and thus to their chemical character) and that their boiling points are linked to their number of carbon atoms in their molecules. High values of Kw (13-12.5) indicate a ...
[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 ...
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 ...
Naphtha (/ ˈ n æ f θ ə /, recorded as less common or nonstandard [1] in all dictionaries: / ˈ n æ p θ ə /) is a flammable liquid hydrocarbon mixture.Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat.

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 It was formerly used to make azo dyes, but it is a known carcinogen and has largely been replaced by less toxic compounds.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]
2-Naphthoic acid is an organic compound of the formula C 10 H 7 CO 2 H. It is one of two isomeric carboxylic acid derivatives of naphthalene , the other one being 1-naphthoic acid . It can be prepared by carboxylation of 1-chloronaphthalene .
