摘要

Abstract

Bipolar membrane electrodialysis (BMED) has already been described for the preparation of quaternary ammonium hydroxide. However

compared to quaternary ammonium hydroxide

di-quaternary ammonium hydroxide has raised great interest due to its high thermal stability and good oriented performance. In order to synthesize

-hexamethylenebis(trimethyl ammonium hydroxide) (HM(OH)

) by EDBM

experiments designed by response surface methodology were carried out on the basis of single-factor experiments. The factors include current density

feed concentration and flow ratio of each compartment (feed compartment:base compartment:acid compartment:buffer compartment). The relationship between current efficiency and the above-mentioned three factors was quantitatively described by a multivariate regression model. According to the results

the feed concentration was the most significant factor and the optimum conditions were as follows:the current efficiency was up to 76.2% (the hydroxide conversion was over 98.6%)

with a current density of 13.15 mA·cm
