What is Tetrabutylammonium Iodide?

Tetrabutylammonium iodide (TBAI) is a commonly used phase transfer catalyst that can increase the reaction rate or effectively promote a variety of chemical reactions. The reagent can be used as an iodine source to generate the iodide required for the reaction in situ, which can avoid the use of some unstable and expensive iodide. In addition, this reagent is also widely used in the dealkylation of esters and ethers.

Tetrabutylammonium Iodide Uses

  1. Tetrabutylammonium iodide (TBAI) was used as a polarographic analysis reagent.
  2. Tetrabutylammonium iodide (TBAI) is used as ion-pair chromatography reagent, phase transfer catalyst, polarographic analysis reagent, organic synthesis.

Production Method of Tetrabutylammonium Iodide

In a round-bottomed flask with a reflux condenser, 200 ml of tri-n-butylamine and 100 ml of iodo-n-butane were placed. After heating on a steam bath for 65 hours, the solids were filtered off, washed with a small amount of ethyl acetate, and dissolved in a minimal amount of cold ethanol. The resulting solution was mixed with an equal volume of 10% potassium hydroxide in ethanol and poured into water. Part of the ethanol was vaporized under lowered pressure to get tetra-n-butylene iodide crystals.It was recrystallized three times in anhydrous ethyl acetate to obtain 150 grams of product.
