| Abstract: | The electronic tetrabutylammonium hydroxide (TBAH) using tetrabutyl amonium bromide(TBAB) as raw material was prepared.At first, the elimination of the metal ions in tetrabutyl amonium bromide (TBAB) solution by the cation exchange resins was systematically studied.The WU-64 cation exchange resin was the most efficient for the elimination of metal ions in tetrabutylamonium bromide solution among the four investigated resins.Then, the preparation of tetrabutylammonium hydroxide was carried out in an electrolyser with tri-chambers and sec-membranes, the current efficiency reached the maximum when the current density was 1000 A·m-2 and concentration of the raw material was 0.7 mol·L-1. Finally, the purification of the product was conducted in a divided cell separated by cation exchange membrane.The contents of Br- and Cl- residued in 15%(mass) TBAH solution after purification were 0.138 mg·kg-1 and 0.784 mg·kg-1 respectively.The results of the experiment can be references for microelectronics industry. |
