Methyl Tributyl Ammonium Bromide

Quaternary ammonium salts are organic compounds that contain a positively charged nitrogen atom as a cation, along with four alkyl or aryl groups attached to the nitrogen atom. One type of quaternary ammonium salt is Methyl Tributyl Ammonium Bromide, also called N-methyl-N-tributylammonium bromide or MTBAB. With the chemical formula C₁₃H₃₀BrN, this colourless or pale yellow, water soluble liquid is used in the production of surfactants and as a corrosion inhibitor in the oil and gas industry. It is known to be an environmentally friendly alternative to other surfactants like alkylphenol ethoxylates.
