ABSTRACT:
A high yield method for the preparation of C.sub.1 -C.sub.20 alkyl or aryl-substituted alkyl, C.sub.8 -C.sub.16 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 C.sub.1 -C.sub.4 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 C.sub.8 -C.sub.12 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.
