This study was initiated at the request of and in cooperation with the naval ship engineering center of the U.S. Department of the Navy. Their interest stemmed from the fact that naturally durable white oak, which has been used for many years in the construction of minesweepers, has become increasingly difficult to procure. A somewhat leach-resistant preservative is considered necessary if a substitute species of lower natural durability is to be used. The substitute species selected by the Navy was red oak, which is not high in natural decay resistance, but does possess the necessary strength properties. When preservatives were being considered, effects on strength and gluability were prime factors, but cost, human toxicity, and efficacy were also important. Based on these considerations, it was decided that a pressure treatment with pentachlorophenol (PCP) in liquefied petroleum gas would be the most satisfactory, provided the preservative was sufficiently permanent. The purpose of this investigation was to obtain information on the permanence of PCP in red oak when leached in artificial seawater.
