a method of producing a tetraalkylammonium quaternary salt of a second anion; and a method of converting a tetraalkylammonium hydroxide quaternary salt to a tetraalkylammonium carbonate / bicarbonate quaternary salt

摘要

A METHOD OF PRODUCING A SECOND NATIONAL TETRAALKYLAMMONY QUARTERNARY SALT AND A METHOD OF CONVERTING A TETRAALKYLAMMONIUM HYDROXIDE SALT TO A CARBONATE / BICARNARAMETH BALARNETARY QUARTERNARY SALT. A novel production process is described for producing quaternary ammonium compounds having a selected anion in which it can be used in wood preservative formulations. The process involves reacting a trialkylamine with an alkyl bromide to form a quaternary tetraalkylammonium bromide salt, converting the quaternary tetraalkylammonium bromide salt to a quaternary tetraalkylammonium hydroxide salt by using an ion exchange resin and converting the tetraalkylammonium hydroxide salt quaternary to a quaternary tetraalkylammonium salt of a selected anion.
