| Research Abstract |
It is well known that organic acids such as formic and acetic acids in indoor air cause the deterioration of cultural artifacts made of metal and inorganic pigment. Thus, novel measurement method of organic acids such as formic and acetic acid emitted from wood and wood adhesives were developed. There were some wood adhesives emitted high concentrations of acetic acid from chemical structure of resin. Emissions of formic and acetic acids from wood were increased with the heat treatment of wood. Determination of emission mechanism of organic acids resulted that the thermal decomposition of α-cellulose in wood cause the acetic acid formation.
