What is Octadecanamide?
Chemical properties
Octadecanamide is a white or light yellow granules. After recrystallization in ethanol, it is colorless leafy crystal. Soluble in hot ethanol, chloroform, ether, insoluble in cold ethanol, insoluble in water. Lubricity is lower than grease right, and the continuity is shorter. Thermal stability is poor, with initial coloring. With a small amount of advanced alcohol (C16 ~ 18) can overcome the above shortcomings.
The Uses of Octadecanamide
Corrosion inhibitor in oil wells.
Definition
ChEBI: Octadecanamide is a fatty amide of stearic acid. It has a role as a metabolite. It derives from an octadecanoic acid.
Flammability and Explosibility
Non flammable
Safety Profile
Questionable carcinogen withexperimental tumorigenic data. When heated todecomposition it emits toxic fumes of NOx.
