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 ...
The z is equal to 0 for saturated, acyclic acids and increases to 2 in monocyclic naphthenic acids, to 4 in bicyclic naphthenic acids, to 6 in tricyclic acids, and to 8 in tetracyclic acids. [5] Crude oils with total acid number (TAN) as little as 0.5 mg KOH/g acid or petroleum fractions greater than about 1.0 mg KOH/g oil usually qualify as a ...

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 .
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 ...
