Camphre, whose IUPAC name is 1,7,7-trimethylbicyclo[2.2.1]heptan-2-one, is a terpenoid organic compound with a chemical formula of C10H16O. It is a white or transparent waxy solid at room temperature and can be used to repel insects. Camphre is extracted from the trunk of camphre tree. The older the camphre tree, the more camphre is in it. The extraction method is to cut the tree trunk into small pieces and distill it with water. After the camphre oil is heated, it rises with water vapor, and it can form camphre when it comes into contact with the pottery jar placed above to cool it. In the early days of northern Taiwan, the mountain forests were mostly primitive camphre forests, and many old camphreles arbres avaient plus de mille ans. Plus tard, le gouvernement japonais a réduit une grande quantité decamphre for export in Taiwan. Therefore, Taiwan's camphre export once reached the first place in the world. Most of the mothballs used in the world are synthesized chemically.This substance may be harmful to the environment, and special attention should be paid to water bodies.Store in a sealed, ventilated, dry place, avoid contact with other oxides.
