Heterogeneous catalysis is catalysis where the phase of catalysts differs from that of the reactants or products. The process contrasts with homogeneous...

Aliquat 336 (Starks' catalyst) is a quaternary ammonium salt used as a phase transfer catalyst and metal extraction reagent. It contains a mixture of...

is a quaternary ammonium salt with a bromide commonly used as a phase transfer catalyst. It is used to prepare many other tetrabutylammonium salts by salt...

chemical formula: [CH3(CH2)7]4N Br. It is generally used as a phase transfer catalyst between an aqueous solution and an organic solution. Tetraoctylammonium...

from tert-butylamine in the presence of catalytic amount of the phase transfer catalyst benzyltriethylammonium chloride. Me3CNH2 + CHCl3 + 3 NaOH → Me3CNC...

'average' chemist is the use of a phase transfer catalyst. This is a charged species that transfers another ion to the organic phase. The ion reacts and then forms...
