Summary:A method for the synthesis of anhydrous quaternary ammonium hydroxides having the formula (NR1R2R3R4)OH, wherein R1, R2, R3 and R4 are the same as or different from one another and are each individually selected from H, C1-C10 alkyls including linear or cyclo alkyls, and C6-C12 aryls by reacting an alkylene oxide with a tertiary amine having the formula R1R2R3N wherein R1, R2, and R3 are the same or different and are each individually selected from C1-C10 alkyls including linear and cyclo alkyls, C1-C10 hydroxyalkyls, C6-C12 aryls, and formulations having anhydrous quaternary ammonium hydroxides. L'invention concerne un procédé de synthèse d'hydroxydes d'ammonium quaternaire anhydres ayant la formule (NR1R2R3R4)OH, dans laquelle R1, R2, R3 et R4 sont identiques ou différents les uns des autres et sont chacun individuellement choisis parmi H, les alkyles en C1-C10 comprenant des alkyles linéaires ou cycliques, et les aryles en C6-C12 par réaction d'un oxyde d'alkylène avec une amine tertiaire de formule R1R2R3N dans laquelle R1, R2 et R3 sont identiques ou différents et sont chacun individuellement choisis parmi les alkyles en C1-C10 comprenant des alkyles linéaires et cycliques, les hydroxyalkyles en C1-C10, les aryles en C6-C12 et des formulations ayant des hydroxydes d'ammonium quaternaire anhydres.
