The Uses of Tetraheptylammonium bromide
Tetraheptylammonium Bromide is a catalyst in organic polymer synthesis involving redox-active crystals of polymetalate. Reagent used in the preparation of ionic liquids as novel quartz collectors.
General Description
Tetraheptylammonium bromide is a quaternary ammonium compound (QAC) mainly used as a phase-transfer agent.
Purification Methods
Crystallise the bromide from n-hexane, then dry it in a vacuum oven at 70o. [Goodrich et al. J Am Chem Soc 72 4412 1950, Beilstein 4 IV 736.]
