1-Hexadecylamine Usage And Synthesis

Chemical Properties

white low melting crystalline mass or chunks

Uses

Dental caries prophylactic.

Uses

1-Hexadecylamine is used for producing resin, senior detergent, anti-caking agent.

General Description

A white waxy solid with an ammonia-like odor. Insoluble in water and less dense than water. Hence floats on water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation or skin absorption. Used to make other chemicals.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

HEXADECANAMINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Flammability and Explosibility

Notclassified

Purification Methods

Crystallise the base from thiophene-free *benzene and dry under vacuum over P2O5. Store away from CO2 [Beilstein 4 IV 818.]
