Quaternary ammonium salts USED AS PHASE TRANSITION ENABLERS

摘要

Quaternary ammonium salts of general formula (I) CHEM wherein: R is a saturated or unsaturated, linear or branched alkyl radical of C1 to C8. R' 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.
