N-HEXADECYLSULFURIC ACID SODIUM SALT Structural

What is N-HEXADECYLSULFURIC ACID SODIUM SALT?

Chemical properties

white solid

The Uses of N-HEXADECYLSULFURIC ACID SODIUM SALT

Sodium Hexadecyl Sulfate is used in preparation of black antibacterial PET film.

General Description

White paste or liquid with a mild odor. May float or sink in water.

Reactivity Profile

Salts, basic, such as N-HEXADECYLSULFURIC ACID SODIUM SALT, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

Health Hazard

Contact with eyes causes mild irritation. May cause skin to dry out and become irritated.

Purification Methods

Recrystallise it from absolute EtOH or MeOH and dry it in vacuum [Abu Hamdiyyah & Rahman J Phys Chem 91 1531 1987].
