    Description

    Applications
    Phase transfer catalyst Tetra-n-butylammonium bromide is used as a phase transfer catalyst for the preparation of lactones by cyclization of potassium salt of µ-bromocarboxylic acids and beta-lactones from beta-bromoacid by cyclization. It is also involved in the Curtius rearrangement, N-alkylation of aromatic carboxamides. It plays an important role as an ionic liquid in the regioselective O-alkylation reactions. It is also used in the preparation of polymer solar cells and single component green-light emitting electrochemical cells.

    Solubility
    Soluble in water and ethanol.

    Notes
    Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.
