A PROCESS FOR PREPARING ANTI-FUNGAL ANIT-WOOD BORER AND ANTI-TERMITE COMPOSITIONS FOR TREATING WOOD

摘要

1. A process for preparing anti-fungal anti-wood borer and anti-termite compositions for treating wood from by-products formed during nitration of toluene comprising the steps of acidification of the aqueous waste stream -"black liquor"- generated in the nitration of toluene with acid to recover the dissolved nitrocresols and structurally similar compounds in the form of total precipitated solids and redissolving the total precipitated solids either in water with caustic lye or in a suitable solvent to get water based and solvent based compositions respectively.
