摘要:
Quaternary ammonium salts of general formula (I) wherein: R is a saturated or unsaturated, linear or branched alkyl radical of C₁ to C₈. Rʹ is a saturated or unsaturated, linear or branched alkyl radical of C₁ to C₁₂, or a benzyl radical. n is a number equal to 2 or 3. X ⊖ is a halogenide anion, such as Cl ⊖ , Br ⊖ , I ⊖ , are used as phase transfer catalysts, in heterogeneous ionic reactions wherein the reagents are in different phase and have different polarity.
