2-Naphthalenethiol Chemical Properties,Uses,Production

Description

2-Naphthalenthiol has a disagreeable mercaptan-like odor. May be prepared by catalytic hydrogenation of a sulfonic acid derivative of naphthalene; by reduction of naphthalenesulfonyl chloride with zinc.

Chemical Properties

2-Naphthyl mercaptan has a disagreeable sulfurous, mushroom, meaty odor

Chemical Properties

Almost white to cream powder

Preparation

By catalytic hydrogenation of a sulfonic acid derivative of naphthalene; by reduction of naphthalenesulfonyl chloride with zinc.

Taste threshold values

Taste characteristics at 10 ppm: sulfurous, meaty, brown, roasted, chicken, eggy with a slight nutty nuance

Safety Profile

Poison by ingestion and intraperitoneal routes. A mosquito larvicide. When heated to decomposition it emits highly toxic fumes of SOx.

Purification Methods

It is steam volatile. It has to be distilled under Ar or N2, as it oxidises to the disulfide, and crystallises from EtOH. The S-methyl derivative has m 104-105o (from *C6H6/pet ether), and the S-ethyl derivative M 188.2, has m 16o and b 175-170.5o/15mm. The S-acetate has m 53.5o and b 191o/15mm, and the diethylamine salt forms yellow needles m 107o from dioxane. [Beilstein 6 H 657, 6 I 316, 6 II 610, 6 III 3006, 6 IV 4312.]
