Камфора, 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. Камфора is extracted from the trunk of камфора tree. The older the камфора tree, the more камфора is in it. The extraction method is to cut the tree trunk into small pieces and distill it with water. After the камфора oil is heated, it rises with water vapor, and it can form камфора 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 камфора forests, and many old камфораағаштар мың жылдан астам уақыт болған. Кейінірек Жапония үкіметі үлкен мөлшерде қысқарттыкамфора for export in Taiwan. Therefore, Taiwan's камфора 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.
