Tetrapropylammonium hydroxide synthesis

Yield:-

Reaction Conditions:

with potassium hydroxide in ethanol at 40; for 12 h;Inert atmosphere;

Steps:

4.1
1) Synthesis of Tetrapropyl Ammonium Hydroxide Ethanol Solution:Tetrapropylammonium bromide (2.7 g, 10 mmol) was placed50 mL of the reaction flask,The reaction flask was evacuated through nitrogen three times,Was added under nitrogenThe distilled ethanolic solution (10 mL),40oC conditions for 10min,KOH solid (0.62 g, 11 mmol) was added,Reaction 12h, the exchange completely filtered,The filtrate was allowed to stand at low temperature for 6 hours under nitrogen atmosphere,And then precipitated solid filter, so repeated 3 times, Can be obtainedTetrapropylammonium hydroxide in ethanol.
