1-Nonanethiol Chemical Properties,Usage,Production

Chemical Properties

CLEAR YELLOW LIQUID

Uses

1-Nonanethiol is a germination stimulator. It stimulates the germination of uredospores of Puccinia graminis tritici.

Uses

1-Nonanethiol is mainly used to form self-organized monolayers on gold, mercury, silver and platinum surfaces. These monolayers functionalize the surface atoms and improve the surface property of the composite.

General Description

Colorless liquid with a bad smell. Mp: -21°C; bp: 220°C. Density: 0.840 g cm-3 at 25°C. Combustible liquid.

Reactivity Profile

1-Nonanethiol is incompatible with oxidizing agents, strong acids and strong bases, alkali metals, and nitric acid. Can react with water, steam or acids to produce toxic and flammable vapors. Reacts violently with powerful oxidizing agents such as calcium hypochlorite (Ca(OCl)2) to generate SOx. React with hydrides to form flammable H2 gas; reacts with halogenated hydrocarbons to yield HX. Reacts exothermically with aldehydes. Emits toxic compounds of sulfur when when heated to decomposition.
