发明名称 METHOD FOR THE SYNTHESIS OF QUATERNARY AMMONIUM COMPOUNDS AND COMPOSITIONS THEREOF
摘要 A method of converting a tetraalkylammonium salt of a first anion to a tetraalkylammonium salt of a second anion is described which involves forming a solution comprising the tetraalkylammonium salt of the first anion in a solvent which includes water and a polar organic co-solvent, contacting the solution with an ion exchange resin in the form of the second anion and forming a tetraalkylammonium salt of the second anion in solution and an ion exchange resin complexed with the first anion. The solution containing the tetraalkylammonium salt of the second anion can be recovered.
