Three kinds of aliphatic alcohols（1-dodecanol,1-tetradecanol,and their mixtures）were selected as solvents to prepare a coloring agent for making thermochromic wood.The colorimetric parameters of the thermochromic wood and the relationship between the solvents melting point and thermochromic properties of the wood were analyzed.The results showed thermochromic property differences existed among the thermochromic wood made with different solvents.The color-change temperature depended on the melting point of solvent.The wood made with solvent with lower melting point,such as 1-dodecanol or mixture of 1-dodecanol with 1-tetradecanol,could have color change at lower temperature.
