N,N-Dimethyloctadecylamine Chemical Properties,Usage,Production

Chemical Properties

N,N-Dimethyloctadecylamine is Solid

Uses

N,N-Dimethyloctadecylamine is used as chemical intermediates for the manufacture of quaternary ammonium compounds, amine oxide and betaine surfactants

Uses

N,N-Dimethyloctadecan-1-amine is a useful reagent for the preparation of cationic gelatin cross-linked with Tannic Acid (T006560(P)).

Definition

ChEBI: Dimantine is a tertiary amino compound.

General Description

N,N-Dimethyloctadecylamine is a clear yellow liquid with a fishlike 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

N,N-Dimethyloctadecylamine 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

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
