精萘的理化性质有哪些?

樟脑丸有天然樟脑丸与合成樟脑丸之分。是一种有机化合物,含有萘的樟脑丸大多呈白色,气味刺鼻,且沉于水中;而天然樟脑丸则是光滑的呈无色或白色的晶体,气味清香,会浮于水中。用于防虫、防蛀、防霉的天然樟脑丸又被称为臭珠,原本是从樟树枝叶中提炼出的有芳香味的有机化合物。也用来制药、香料等,医药上用作强心药。而含有萘或者对二氯苯的合成樟脑丸则有刺鼻的味道,二氯苯有毒性,它能引起人体中毒症状,如倦怠、头晕、头痛、腹泻等。目前市面上出售的樟脑丸80%以上均不同程度地含有萘或者对二氯苯,印有“绝不含萘和对二氯苯,安全、高效、对人体无毒无害”的产品不到1/6。因此选购防蛀剂时一定要注意包装袋上标注的成分,切莫忽视。

Camphor balls can be divided into natural camphor balls and synthetic camphor balls. It is an organic compound, and camphor balls containing naphthalene are mostly white in color, have a pungent odor, and sink in water; Natural camphor balls, on the other hand, are smooth, colorless or white crystals with a fragrant odor that floats in water. Natural camphor balls, also known as stinky beads, used for insect, moth, and mold prevention, were originally aromatic organic compounds extracted from camphor tree branches and leaves. It is also used in pharmaceuticals, spices, etc., and is used as a cardiac stimulant in medicine. Synthetic camphor balls containing naphthalene or p-dichlorobenzene have a pungent taste, while dichlorobenzene is toxic and can cause symptoms of poisoning in the human body, such as fatigue, dizziness, headache, diarrhea, etc. At present, more than 80% of the camphor balls sold on the market contain varying degrees of naphthalene or p-dichlorobenzene, and less than 1/6 of the products are printed with "no naphthalene or p-dichlorobenzene, safe, efficient, non-toxic, and harmless to the human body". Therefore, when choosing mothproof agents, it is important to pay attention to the ingredients marked on the packaging bag and not ignore them.

樟脑是酮类, 分子式为C10H16O。它是从天然樟木得到的晶体。它特别的香味由晶体升华出来, 能够用于医药及预防昆虫蛀蚀等方面。正因为它无毒和对人体和衣服没有任何坏影响, 所以使用樟脑是安全的。

Camphor is a ketone with the molecular formula C10H16O. It is a crystal obtained from natural camphor wood. Its unique fragrance is sublimated from crystals and can be used in medicine and prevention of insect infestation. Because it is non-toxic and has no harmful effects on the human body and clothing, using camphor is safe.

臭丸是由萘制造而成,萘是从原油或煤焦油提取的一种稠环芳烃化合物。它升华出来的“臭”气有毒性, 尤其伤害肝脏。它也对丝绸和尼龙有化学反应, 所以在这些衣服上会出现一些孔洞。当我们使用臭丸时, 使用1——2个球已足够, 记紧要用布包着这些臭丸, 以避免臭丸与衣服的直接接触。

Stinky pills are made from naphthalene, which is a polycyclic aromatic compound extracted from crude oil or coal tar. The "odor" it sublimates is toxic, especially harmful to the liver. It also has a chemical reaction with silk and nylon, so some holes will appear on these clothes. When using stink balls, using 1-2 balls is sufficient. Remember to wrap these stink balls in a cloth to avoid direct contact between them and clothing.
