THE EFFECT OF SOLVENT EXCHANGE ON THE PIT ASPIRATION IN ORIENTAL SPRUCE (Picea orientalis (L.) Link.) WOOD
Abstract
This study investigated the effect of solvent Exchange drying utilizing low surface tension force of organic solvents on pit aspiration in Oriental spruce wood. All trees used for experiments were obtained from Maçka-Karahava region. Investigations for pit aspiration was carried out on electron microscope. Prior to the experiments, samples dried with solvent Exchange method. The principle of this method was the replacement of free water in wood with an organic solvent, low in surface tension. The applied organic solvents were acetone, benzene and pentane. For comparison purposes, pit aspiration experiment also were conducted on oven-dried and air-dried wood samples. Result inticated that solvent Exchange drying was observed to be effective on pit aspiration, and the best result was obtained by acetone treatment.
