일반 설명
Tetrabutylammonium tetrafluoroborate (TBATFB) is a phase transfer catalyst. It can be synthesized by the reaction between 30% aqueous solution of tetrafluoroboric acid and 40% aqueous solution of tetrabutylamonium hydroxide. Tetrabutylammonium tetrafluoroborate acts as an electrolyte and inhibits the self-assembly of alkylthiosulfate on gold.
Purification Methods
Recrystallise it from H2O, aqueous EtOH or from EtOAc by cooling in Dry-ice. Also recrystallise it from ethyl acetate/pentane or dry acetonitrile. Dry it at 80o under vacuum. [Detty & Jones J Am Chem Soc 109 5666 1987, Hartley & Faulkner J Am Chem Soc 107 3436 1985.] The acetate has m 118±2o (from BuCl), the bromide has m 118o (from EtOAc) and the nitrate has m 120o (from *C6H6).
