N,N-Dimethylaminobutane Chemical Properties,Usage,Production

Chemical Properties

colourless liquid

Uses

Dimethylbutylamine is used as a chemical intermediate.

Uses

N,N-Dimethylbutylamine (cas# 927-62-8) is in preparation of high-density rigid flame-retardant polyimide foam material.

Uses

N,N-Dimethylbutylamine is suitable for use in the fabrication of polystyrene-based nano-LC monolithic columns for the separation of protein molecules. It may be used as ion-pairing reagent in a study involving comparison of performance of six ion-pairing reagents as mobile phase modifiers for oligonucleotide LC/MS.

Definition

ChEBI: A tertiary amine consisting of n-butane having a dimethylamino substituent at the 1-position.

General Description

A clear liquid with an ammonia-like odor. Flash point 20°F. Boiling point 201°F. Density 0.72 g / cm3. Ingestion may irritate or burn the mouth, throat, esophagus and stomach. May cause nausea, vomiting and diarrhea. Inhalation of vapors may irritate the respiratory system and cause pulmonary edema. Contact with the skin may cause burns. Eye contact may cause corrosion to the eyes and contact with the vapor may temporarily blur vision. Vapors heavier than air and may travel considerable distance to a source of ignition and flash back.

Air & Water Reactions

Highly flammable. Partially soluble in water.

Reactivity Profile

N,N-DIMETHYL-N-BUTYLAMINE 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.

Hazard

Moderately toxic by ingestion. Low toxic- ity by inhalation and skin contact. A moderate eye irritant.

Health Hazard

May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Flammability and Explosibility

Non flammable
