BASIC STUDY ON THE CHEMICAL REACTION BETWEEN OZONE AND SESQUI-TERPENES EMITTED FROM CEDARWOOD

摘要

Full-scale chamber of test house was used to investigate emission data of sesqui-terpenes from cedarwood. This experiment involved placing samples of cedarwood and an ozone generator in one room of the test house. The sesqui-terpenes were identified. The indoor sesqui -terpenes concentration with ozone emission was much lower than that without ozone emission. It was found that the higher the indoor ozone concentration, the lower the sesqui-terpenes concentration. The sesqui-terpenes might have been consumed by the reaction with ozone during the experiment. The concentrations of formaldehyde (HCHO) were not changed regardless of the change of ozone concentration.
