Phenol 4 Chloro 3 Iodo

This is a question about the chemical properties of an article (the product 4-hydrogen-3-terpene pinone). This terpene pinone substance has unique chemical characteristics. Its molecular structure contains a specific combination of carbon, hydrogen and oxygen atoms, resulting in its corresponding chemical activity.
In terms of reactivity, the carbonyl group of terpene pinone is electrophilic and can react with nucleophiles. In the case of nucleophiles containing active hydrogen, such as alcohols, under appropriate conditions, the carbonyl carbon can combine with the oxygen atom of the alcohol to produce hemiketal or ketal products. This reaction is often used in organic synthesis to protect the carbonyl group, which can be protected from being affected during a specific reaction step, and its activity can be restored at an appropriate time.
And because it contains unsaturated bonds, it can participate in the addition reaction. Such as with halogen elementals, such as bromine, under suitable conditions, unsaturated bonds can be added to bromine, and bromine atoms are added to both ends of the unsaturated bond to cause molecular structure changes. This reaction can be used to detect the existence of unsaturated bonds in molecules, and it is also a means of introducing bromine atoms in organic synthesis.
In terms of solubility, because the molecule contains polar carbonyl and non-polar hydrocarbon skeletons, it has a certain solubility in polar organic solvents such as ethanol and acetone, and also has a certain solubility in non-polar solvents such as n-hexane. This property makes it a specific consideration in separation, purification and solvent selection.
In addition, terpene pinone has a specific performance in redox reactions. In case of suitable oxidants, the carbonyl group can be further oxidized to higher oxidation products such as carboxyl groups; in case of reducing agents, the carbonyl group can be reduced to alcohol hydroxyl groups. This redox reaction can be used to construct different functional groups and enrich the variety of compounds in organic synthesis.

Borax, also known as moonstone, has a wide range of uses. In the art of alchemy, borax is an essential medicine. Ancient alchemists, alchemy to seek medicine for longevity, borax because of its characteristics, can help the combination of various medicines, so that the color of the pill is better, in the control of fire, coagulation of medicinal pills are wonderful.
In metallurgy, borax has a significant effect. It can be used as a flux, which can remove impurities in metal ores and make metal refining more pure. When casting, cast borax in the furnace, which can reduce the melting point of the metal, make it flow better, the shape of the cast is more complete, and the texture is denser.
In the way of medicinal use, borax also has a place. Its cold nature, sweet and salty taste, has the effect of clearing heat and detoxifying. Borax is often used as medicine for swelling and pain in the throat and sores in the mouth. Or as a detergent, blow on the affected area; or fry water and gargle, it can relieve pain, clear away heat and reduce swelling, and treat various diseases of the mouth and throat.
In the matter of preserving food, borax was also used as a method. In the past, there was no method of refrigeration today. People put a little borax into food, which can slow down its decay. However, eating more borax is harmful to the body. Today, this method is no longer used for food.
In the art of ceramic glazing, borax is indispensable. Adding borax to ceramic glaze can increase the luster of the glaze, make it more colorful, and can reduce the melting point of the glaze. It is easier to apply the glaze. When firing, the glaze surface is uniform and there are fewer defects. Glass production, borax also helps it melt, increasing its transparency, making the glass crystal clear and radiant.

The method of combining saltpeter and sulfur to make gunpowder recorded in "Tiangong Kaiwu" includes many kinds.
One method is to take saltpeter and sulfur, and match them with charcoal. Saltpeter is yang and dry, sulfur is yin and fierce, and charcoal is mixed in between. First study saltpeter very fine, then study sulfur and charcoal, all of which are like powder. Then in an appropriate proportion, mix the three evenly. The amount of saltpeter is usually seven or eight times ten, sulfur is about one or two times ten, and charcoal is also one or two times ten. When mixing, be careful and stir it slowly, so as not to let dust fly, so as to prevent unexpected explosions.
The second method is to dissolve saltpeter in water first, remove its impurities, then boil it to dry, and then re-grind it to the end. Sulfur is also refined to remove its residue and grind it to a very fine level. Charcoal is selected from strong wood, fired into charcoal, and then ground into powder. The three are prepared, mixed in proportion, and stirred evenly.
The third method, or when dispensing medicine, add a little other things. If a little arsenic is added, it can increase the fierceness of gunpowder; or add a little oil to make the medicine bond, which is conducive to forming and ignition. However, arsenic is highly toxic, so use it with caution.
All these methods of synthesis are the crystallization of the wisdom of the ancients. When making gunpowder, strictly abide by the rules and operate carefully, in order to obtain the medicine that can be used to defend against the enemy, open mountains and other things. However, the power of gunpowder is huge, and when handling it, if you are not careful, it will cause disaster, so you can't ignore it.

Mercury is a highly toxic substance. During storage and transportation, the following things must be paid attention to:
First, the need for sealing. Mercury is volatile and its vapor is highly toxic. Therefore, it must be stored in a tightly sealed container to prevent the volatilization of mercury from escaping. If it is packed in a thick-walled glass container or a metal container, make sure that the lid of the container is well sealed and there is no risk of leakage.
Second, the environment is suitable. The storage place should be cool, dry and well ventilated. Avoid direct sunlight, because the temperature will cause mercury volatilization to accelerate. At the same time, the humidity should not be too high to prevent the container from rusting and causing mercury leakage. Good ventilation can disperse the mercury vapor that may evaporate in time and reduce the concentration of mercury in the air.
Third, keep away from fire and heat sources. Although mercury is not flammable, it may evaporate faster in case of hot topics, and high temperature may affect the container, increasing the risk of rupture and leakage.
Fourth, store separately. Mercury must not be mixed with other chemicals to prevent chemical reactions and generate more dangerous substances. And mercury of different purity and use should also be stored separately for easy management and access.
Fifth, caution in transportation. When transporting mercury, use stable and shockproof packaging materials to ensure that the container will not be damaged due to bumps and collisions during transportation. Transportation vehicles also need to be equipped with necessary emergency treatment equipment and protective equipment. If there is a leak, they can be dealt with in time.
Sixth, the logo is clear. Whether it is a storage container or a transportation package, the words "highly toxic" and "mercury" should be clearly marked so that the contact person can see it at a glance, and be vigilant to avoid accidental contact and misuse.
Only in this way can we ensure that mercury is safe during storage and transportation and avoid disasters.

Mercury, commonly known as mercury, is the only metal element that is liquid at room temperature and pressure. It plays an important role in alchemy, but it is very harmful to the environment and human health.
Mercury is highly volatile and easily forms mercury vapor in the air. If inhaled, it can cause damage to the nervous system, kidneys and respiratory system. Light headaches, dizziness, fatigue, insomnia, dreams, forgetfulness, etc., severe tremors, ataxia, mental disorders, etc., or even life-threatening. And mercury vapor is colorless and odorless, difficult to detect, making it difficult to prevent.
Mercury also has a profound impact on the environment. With industrial activities, mercury is released into the environment, and after complex transformation, it can be changed into methylmercury. Methylmercury is highly neurotoxic and accumulates in organisms and is transmitted and amplified through the food chain. If fish are enriched with methylmercury, humans will ingest a large amount of methylmercury if they eat contaminated fish.
Mercury also pollutes soil and water bodies. In soil, it inhibits plant growth and development, resulting in reduced crop yield and quality; in water bodies, it affects the survival and reproduction of aquatic organisms and destroys the aquatic ecological balance.
Therefore, although mercury is used for special purposes in alchemy, in view of its great harm to the environment and human health, the use and discharge of mercury are strictly controlled at present, aiming to reduce mercury pollution and protect the ecological environment and human health.
