1-Butylimidazole Usage And Synthesis

Chemical Properties

Clear Colorless Oil

Uses

1-(n-Butyl)imidazole is used in the synthesis of a heterocyclic mesomeric betaine and 1-(1-butyl-3-imidazolio)propane-3-sulfonate (BIm3S). It acts as an N-coordinated ligand. It is used in the chiral separation of amino acids and anionic pharmaceuticals by capillary electrophoresis. It is used for preparation of substituted phenyl-containing imidazolium ionic liquid.

Uses

1-Butylimidazole may be used in the synthesis of a heterocyclic mesomeric betaine. It was used in the synthesis of 1-(1-butyl-3-imidazolio)propane-3-sulfonate (BIm3S).

General Description

A colorless to light yellow colored liquid. Insoluble in water and more dense than water. Hence sinks in water. Contact may irritate skin, eyes or mucous membranes. Toxic by ingestion, inhalation or skin absorption.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

1-Butylimidazole 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

Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. 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. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
