Field testing of alkylammonium wood preservatives

IRG/WP 3248

J N R Ruddick

The field test performance of five alkylammonium wood preservatives is described. The relative effectiveness of three unmodified formulations was determined by calculation of a Performance Index. Of the three, didecyldimethylammonium chloride was found to be superior to octyldecyldimethylammonium chloride, and both were more effective than alkyltrimethylammonium chloride. However, none were considered to have potential for use as wood preservatives. The addition of cupric chloride to octyldecyldimethylammonium chloride did not improve its effectiveness. Initial results for alkyldimethylbenzylammonium chloride modified by the addition of tributyltin chloride indicated that the preservative performance may be significantly improved.
