A high yield method for the preparation of C1-C20 alkyl or aryl-substituted alkyl, C8-C16 alkyl quaternary ammonium-hydroxide is provided whereby two reactants, a corresponding quaternary ammonium chloride and a metal hydroxide, are reacted in a solvent comprising a C1-C4 normal alcohol. The amount of metal hydroxide reactant is that amount sufficient to yield the quaternary ammonium hydroxide and a metal chloride. Also provided are wood preservative systems which include (a) a biocidal effective amount of at least one di C8-C12 alkyl quaternary ammonium hydroxide and (b) a solvent, as well as a method for preserving a wood substrate whereby the substrate is treated with the preservative system.
