General description

Tetrabutylammonium hydroxide is a quaternary ammonium salt mainly used as a strong base and phase-transfer catalyst.[1]
Tetrabutylammonium hydroxide solution serves as a phase-transfer catalyst in the transesterification of soybean oil.[2]


We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is highly effcient and enhance catalytic efficiency. Click here for more information.

Application

Tetrabutylammonium hydroxide solution (1M in methanol) may be used as a base to synthesize ring methyl and methylene deuteriated porphyrins and metalloporphyrins.[3] It may also be used as an initiator of graft polymerization between pivalolactone and poly(ethylene-co-vinyl acetate-co-methacrylic acid).[4]
