General description

Trimethylamine is a tertiary amine used as a versatile building block in organic synthesis to produce choline chloride, surfactants and solvents, rubber chemicals, tetramethylammonium hydroxide, cationic starches, phase transfer catalysts, ion-exchange resins, and some basic dyes.

Application

Trimethylamine can be used as:
  • A base in dehydrochlorinations, nucleophilic substitutions, 1,4-additions, and aldol-type condensation reactions.
  • A reactant for the preparation of trimethylamine-based dicationic ionic liquids for the extraction of phenolic compounds from oil mixtures.

Packaging

500ml high pressure aluminum cylinder equipped with a stainless steel valve according to DIN 477-1.

Other Notes

For 744379-280G-EU and 744379-280G packaging: 500 mL of aluminium cylinder equipped with stainless steel valve.

Recommended products

For 744379-280G-EU and 744379-280G: outlet fitting: DIN 477-1 no. 1, Z742162 or Z742164 are the recommended regulators.
