|Section2= |Section3= }} Benzyltrimethylammonium hydroxide, also known as Triton B or trimethylbenzylammonium hydroxide, is a quaternary ammonium salt that functions as an organic base. It is usually handled as a solution in water or methanol. The compound is colourless, although the solutions often appear yellowish.〔Mary Ellen Bos "Benzyltrimethylammonium Hydroxide" in Encyclopedia of Reagents for Organic Synthesis, 2001 John Wiley & Sons. 〕 Commercial samples often have a distinctive fish-like odour, presumably due to the presence of trimethylamine via hydrolysis. ==Uses== Together with benzyltriethylammonium salt, benzyltrimethylammonium hydroxide is a popular phase-transfer catalyst.〔Marc Halpern "Phase-Transfer Catalysis" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. 〕 It is used in aldol condensation reactions and base-catalyzed dehydration reactions. It is also used as a base in Ando's Z-selective variant of Horner-Wadsworth-Emmons Olefination reactions.〔Chaturvedi, D., & Ray, S. (2006).
