Special application of camphor wood

Cinnamomum camphora is a good talent in architecture and furniture, which is not deformed and insect-resistant. Folk use it to make furniture, sculpture, wood products and home decoration. The trunk and roots of mature camphor trees contain as much as 20-25% camphor and camphor oil.

China's camphor wood boxes are well-known at home and abroad, including suitcases, sleeping boxes (suitcases), top boxes and cabinets. Only tables and chairs are mostly in Beijing. In the old wood industry, camphor wood is divided into several types according to its shape, such as camphor, camphor tree, camphor tree, camphor tree, camphor tree, camphor tree and so on.

Folk carved Buddha statues with camphor wood. Camphor is a granular crystal distilled from the roots, stems, branches and leaves of camphor tree. Warm in nature and pungent in taste; It can clear the orifices, remove filth, warm the middle warmer, relieve pain, promote diuresis and kill insects. It is the most important raw material tree species for extracting chemical raw materials such as camphor (molecular formula C 10H 16O), camphor oil and linalool. China is the largest camphor wood producer and camphor exporter in the world. Camphor oil is mainly concentrated in the trunk and roots of Cinnamomum camphora, distilled in water. Camphor and camphor oil are distilled by steam, and the white crystals obtained by condensation are crude camphor, and the oily liquid is camphor oil. The chemical composition of natural camphor (molecular formula C 10H 16O) is the same as that of synthetic camphor, and there are two kinds: powder and block. Natural camphor has high purity and high specific rotation. Although it has the same composition as synthetic camphor, it is still difficult to completely replace synthetic camphor in special applications such as medicine.

Camphor oil is mainly composed of camphor and other essential oils (such as eucalyptus, linalool, turpentine and safrole) and by-products (such as white camphor oil, red camphor oil and blue camphor oil). A variety of terpenoids.

The chemical name of camphor is camphorone -[2], and its molecular formula is C 10H 16O. It is colorless to white translucent block or powder, and has the smell of camphor wood. Mainly used for manufacturing celluloid, chemical pigments, photographic films, explosives, spices, pesticides, medicines and so on. It can prevent insects, prevent corrosion and deodorize. With fragrant smell, it can also be used to make daily necessities: moth balls, moth balls, moth-proof incense tablets, mesh bag incense balls, protective articles for hanging sweet cake and other clothes, furs, books, specimens and files. (According to relevant national standards, such goods are marked with poisons. )

Natural camphor is a granular crystal made from camphor wood by steam distillation, extracted from the obtained camphor oil, and distilled from roots, branches, leaves and wastes. In addition to the spring equinox to the long summer, leaves can be picked at other times and camphor oil can be extracted by distillation. Roots contain the most camphor oil, followed by stems and leaves. Because camphor wood lacks extensive resources, it is scarce and expensive. Because of its safety and environmental protection, it is the most popular pesticide in the family. When choosing, we must be more careful about the use of the following two types of products. 1. Naphthalene pills (commonly known as sanitary balls and fake camphor) are toxic chemicals, which are very harmful to human health. The production and sales in 1993 are forbidden by the state, but they can still be seen occasionally in the market; The second category is "p-dichlorobenzene" products. This kind of insect repellent is very toxic, and its insecticidal effect is really good, but it will also kill people. The World Health Organization (W HO) environmental protection and health care standard (published in 199 1) points out that "p-dichlorobenzene" is carcinogenic to animals. The International Chemical Safety compiled by the European Commission and the International Agency for Chemical Safety points out that the substance may act on the liver, kidney and lung, form hemoglobin iron and discolor the skin. The wood aroma of Cinnamomum camphora is usually weak, while the bark of Cinnamomum camphora has a strong cinnamon aroma, and its bark is the raw material for spice utilization.
