Question 1: What is the main chemical composition of mothballs? Hygiene balls are also called mothballs. In daily life, many people in the storage of clothes, books, suitcases, closets, drawers, bookcases, the use of mothballs to kill moths, so as not to bite the clothes and books, there is a certain role in killing, but this is not good for human health, especially for children more harmful. Because, sanitary ball is not real camphor, but from petroleum or coal tar refined from a by-product, its main chemical composition is naphthalene and naphthalene phenol derivatives, with a certain degree of toxicity. If people inhale the air containing naphthalene vapor for a long time, it can cause weakness, headache, loss of appetite, nausea and other reactions. In severe cases, it may also affect vision and damage the kidneys. In children, there is a genetic defect that causes hemolytic anemia: a lack of the enzyme glucose-6-phosphate dehydrogenase in the red blood cells of the child's blood. This disease usually does not show any symptoms, but when exposed to naphthol and other substances, the redox process in the red blood cells will be impeded, so that the cell membrane of the red blood cells will be damaged, and acute hemolytic anemia occurs. At the same time, according to domestic and foreign data in recent years, coal tar is also the first group of carcinogenic substances. Many countries have banned its use in daily life. In addition, sanitary ball will make white fabrics yellowing, chemical fiber fastness and strength decline. Therefore, sanitary balls should not be used frequently in daily life. If the clothes have been stored for a long time, they must be fully air-dried before wearing, so that when it is heated, the naphthol substances turn into gas and evaporate. Camphor essence block is also called refined camphor block is the real camphor. It not only does not affect the quality of chemical synthetic fiber, but also has no toxic effect on human body. Therefore, the camphor essence block is currently used to collect clothes, books, the ideal standing products.

Question 2: What is the composition of natural camphor pills Natural camphor: its systematic naming: (1R,4R)-1,7,7-trimethylbicyclo[2.2.1]heptane-2-ketone

Note: In the past, "naphthalene" as a camphor substitute may be possible (in the last century, China is still poor and penniless), naphthalene is a poisonous substance. Naphthalene is a toxic substance, naphthalene and natural camphor are not the same substance

Naphthalene:

Question 3: The main ingredient of camphor balls is Camphor The main ingredient of camphor balls is camphor.

The chemical structure is a bicyclic ketone, chemical name: 1,7,7-trimethylbicyclo[2.2.1]heptan-2-one. It has a special aromatic *** flavor.
