Tetrabutylammonium bromide Usage

(1) Used as a polarographic analysis reagent and also for organic synthesis.

(2) Tetrabutylammonium bromide is also an effective phase transfer catalyst.

A phase transfer catalyst, abbreviated as PTC, is a catalyst capable of transferring a reactant of an aqueous phase (or an organic phase) to an organic phase (or an aqueous phase), that is, a catalyst capable of reacting between an aqueous phase and an organic phase. The PTC has properties such as changing the degree of solvation of ions, increasing ion reactivity, and speeding up the reaction. It solves the problem that the reactants in the past two phases are difficult to react.

Commonly used quaternary ammonium salt phase transfer catalysts are: benzyltriethylammonium chloride, trioctylmethylammonium chloride, tetramethylammonium bromide, tetrapropylammonium chloride, tetrabutylammonium bromide , tetrabutylammonium iodide, triethylbenzylammonium bromide, triethylhexylammonium bromide, triethyloctyl ammonium bromide.

The phase transfer catalyst is widely used in organic synthesis: for preparing R2C type compound (carbene type compound), and further preparing corresponding nitrile, isonitrile, halogenated alkane, dichlorocyclopropane derivative, hydroxycarboxylic acid and diazomethane; Used in alkylation reaction, it can avoid harsh conditions such as anhydrous operation and high product yield compared with traditional methods; it can also be used for redox reaction, ester hydrolysis, cyanide halide displacement reaction, condensation reaction, addition Reaction, polymerization, carbene ring addition reaction, elimination reaction, and the like.
