I don't want to, but I can't tolerate nonsense.
Phenol: Colorless crystals, pink color due to oxidation in the air.
Smelling a smell cannot be considered volatile. Being volatile does not mean being volatile. Phenol is volatile, but not very volatile.
-
Yes. You know when you smell it. It has a peculiar smell.
If it doesn't volatile, it won't smell.
-
It is very volatile.
Get it in your hands. And the skin became pale and pale.
Just use alcohol.

After all these years, phenol is now a nationally recognized volatile organic compound.

Benzene usually evaporates after 6 months to 3 years. In addition to the concentration, the evaporation rate of benzene also depends on the temperature of the environment and the degree of air circulation. Regarding the specifics of "how long does benzene take to volatilize", if you are interested, you can continue to read and understand.
1. The circulation of air can dilute the benzene in the air, if you want the benzene to volatilize quickly, you can open the indoor windows, doors, exhaust fans, fans, etc., so that the air can circulate quickly.
2. The adsorption capacity of activated carbon is very strong, and the use of activated carbon can also adsorb benzene in the air, and activated carbon is placed in various corners of the room, which can accelerate the volatilization of benzene.
3. Some common green plants have the effect of purifying the air and can adsorb benzene in the air to a certain extent, but the volatilization of benzene by plants can only play an auxiliary role, and it is necessary to combine other methods to make benzene volatilize quickly.
4. High temperature can also speed up the volatilization of benzene, when there is no one at home, you can turn on the heating function of the air conditioner, and volatilize the benzene through the morning shed beam to raise the indoor temperature.
<> benzene is toxic, benzene is an organic compound, which will have a certain impact on the human body, if the human body is exposed to too much, it will produce symptoms such as dizziness, nausea, and headache.

Xylene is volatile, but not easily volatile.
Xylene is a colorless transparent liquid with a relative density of about. The flash point is closed cup). The melting point is -48, the boiling point is 137, the vapor density is times that of air, the vapor pressure (20) is about 700pa, flammable, and the explosion limit of vapor and air mixture is .
The surface tension is about. Soluble in ethanol and ether, insoluble in water.
The boiling points of the three isomers are: o-xylene, m-xylene, and p-xylene. Paraxylene is a colorless monoclinic crystal with a relative density of 13 and a boiling point of 138.
In the quality index of petroleum mixed xylene products (GB T 3407-2010), the relative density of 5 mixed xylene (20) is 137 143; 3 The distillation range of mixed xylene is.
-
Summary. Pro, phenol, cresol and xylenol are all volatile phenols, and diphenols and polyphenols are non-volatile phenols.
Pro, phenol, cresol and xylenol are all volatile phenols, and diphenols and polyphenols are non-volatile phenols.
So the volatile phenol may be phenol, but not necessarily or cadaveric cresol xylenol.

Benzene is a common organic compound, which is easy to volatilize at room temperature. This is because the benzene molecule is highly volatile, and its molecular collision structure makes it easy to convert from a liquid to a gaseous state. In addition, the boiling point of benzene is relatively low, which is only, so it can be quickly steamed at room temperature.
The volatility of benzene makes it widely used in many industrial fields. For example, benzene is used as a solvent, stain remover, pigment, fragrance, and many more. At the same time, there are dangers.
Due to the strong toxicity of benzene molecules, inhaling excessive amounts of benzene gas is harmful to health. Long-term exposure to benzene gas can also lead to the occurrence of diseases such as leukemia.
Therefore, it is important to take the necessary safety measures during the use of benzene, such as using it in a well-ventilated area, following correct operating procedures and using personal protective equipment. In addition, we should also try to avoid exposure to benzene-containing products, such as excessive tobacco and alcohol, air pollution, etc. These measures can effectively reduce the health risks posed by benzene.
In short, the volatility of benzene is determined by its molecular structure and physical properties. In the process of using benzene, it is necessary to pay attention to safety and minimize the harm to the human body.
Mercury can evaporate at room temperature, and its vapors and compounds are often highly toxic (chronic). On October 27, 2017, the World Health Organization's International Agency for Research on Cancer (IARC) published a preliminary list of carcinogens, and mercury and inorganic mercury compounds were included in the list of three types of carcinogens. [2] On July 23, 2019, mercury and mercury compounds were included in the list of toxic and harmful water pollutants (the first batch).
Medicated soap is made by adding an appropriate amount of phenol and cresol mixture (preservative, sterilization) or boric acid to soap. Other soaps are non-phenol-free.
