Product Introduction:

Tetrabutylammonium Bromide is an important organic salt in chemical form (C₄H₉) ₄N + + Br⁻. It is a white crystalline solid, deliquing, stable at room temperature, and has a special odor. Tetrabutylammonium Bromide soluble in water, alcohol, ether and acetone and other solvents, slightly soluble in benzene, its molecular weight of 322.368, melting point between 102℃-118℃, refractive index of 1.422, density of 1.039 g/mL (25℃).

As a quaternary ammonium compound, Tetrabutylammonium Bromide has unique chemical properties. It can be completely dissociated into tetrabutylammonium cation and bromine ion in aqueous solution with A cationic radius of 4.94 A. Its ionic conductance in water is 1.953×10⁻³ m²/Ω·mol and 7.814×10⁻³ m²/Ω·mol (25℃).
Its synthesis reaction is usually regarded as a second-order reaction, which may be carried out through the SN2 reaction mechanism, and the activated intermediate will be produced during the reaction process, which will affect the order degree and entropy change of the reaction.

Tetrabutylammonium Bromide has a wide range of applications in many fields. It is an efficient phase transfer catalyst, often used in two phase reaction systems, such as water-organic phase, can promote the transfer and reaction of reactants at the interface, thereby improving the reaction efficiency and selectivity.
In organic synthesis, it can be used in processes such as alkylation, acylation and polymerization reactions, as an intermediate or catalyst. In addition, it is used as an electrolyte additive in electrochemical synthesis, and as a raw material for the preparation of surfactants and emulsifiers.

In industrial applications, Tetrabutylammonium Bromide is mainly used in pharmaceutical, chemical and electrochemical fields. In the pharmaceutical industry, it can be used to catalyze key steps in drug synthesis, such as the formation of carbon-nitrogen bonds and carbon-oxygen bonds. In chemical production, it is used to synthesize fine chemicals such as dyes, fragrances and polymer materials.
Due to its toxicity, it is necessary to pay attention to safety protection when using, avoid contact with the skin and inhalation of dust, while storage should keep the container sealed, placed in a cool, dry place, to avoid contact with oxides and moisture.
