6-quinolinecarbonitrile, 2-chloro-

6-Square light ether, a colorless and transparent liquid, has a special aromatic gas, is highly volatile, and its vapor is heavier than air. Its boiling point is about 34.6 ° C, the melting point is -116.3 ° C, the relative density (water = 1) is 0.7134, and the relative vapor density (air = 1) is 2.55.
This liquid is highly flammable, and its vapor can form an explosive mixture with air. In case of open flame or hot topic, it is very easy to burn and explode. It can react strongly with oxidants. After being left in the air for a long time, it can form explosive peroxide. Its vapor is heavier than air and can spread to a considerable distance at a lower place. In case of fire, it will catch fire and burn back. < Br >
Because of its volatility, when using and storing, it should be sealed and stored in a cool and ventilated place, and away from fire and heat sources. The storage temperature should not exceed 26 ° C. During handling, it should be handled lightly to prevent damage to packaging and containers.

6 - Fangguang ether, this material is unique and has several properties. It is volatile, and at room temperature, it is easy to turn into gas, like light smoke, and drifts in the air. Its taste is specific, pungent to the smell, uncomfortable to the nose, and this smell is easy to identify in the air.
Furthermore, it is flammable. In case of an open fire or hot topic, it will ignite in an instant, and the flame will rise up, like lightning, burning, dazzling fire, and when burning, or accompanied by an explosion, a crisis will occur.
6 - Fangguang ether can be miscible with many organic solvents, such as water, alcohols, ketones, etc., and can be mixed with it, just like water milk, regardless of each other. In chemical reactions, it is often used as a solvent to provide a suitable environment for the reaction, and also participates in some specific reactions, which affects the process and results of the reaction.
However, its toxicity cannot be underestimated. If the human body comes into contact with it, or inhales its gas, or is contaminated with the skin, it can be harmful. Light cases are dizziness, dizziness, nausea, vomiting, and severe cases are life-threatening, damaging internal organs, and causing human dysfunction. Therefore, when using and storing 6-square light ether, it is necessary to strictly abide by the procedures and be careful to prevent accidents. It must be placed in a cool and ventilated place, away from fire and heat sources, and protective equipment must be worn during operation to ensure safety.

The use of mercury has been quite important throughout the ages. The main use of mercury in the hexagonal light sand is not just one end.
Those who bear the brunt are in the realm of alchemy cultivation, and the status of mercury in the hexagonal light sand is respected. Ancient alchemists believed that based on mercury, combined with all kinds of gold and stone, they could obtain elixirs for longevity. "Baopuzi" has a saying: "Cinnabar is gold, and the sergeant who takes it to ascend to immortality is also a sergeant." Mercury in it, either as a medium for transforming gold and stone, or as a key ingredient for the formation of medicinal pills. Although this was a lot of false thinking, in the world where alchemy was prevalent at that time, mercury in hexagonal glossy sand was an indispensable material, which attracted countless alchemists to flock to it and devote their efforts to studying the art of mercury refining.
Furthermore, in the process of medical treatment, mercury has also shown its presence. Ancient physicians knew that mercury has the ability to disinfect and sterilize. Medicines made with hexagonal glossy mercury may be used for the disease of scabies. For example, the Compendium of Materia Medica states that mercury can "kill insects, disinfect, and remove sores." Although the toxicity of mercury is also known to physicians, it is still used in subtle ways to treat specific diseases and weigh the advantages and disadvantages.
In the metallurgical industry, hexagonal glossy mercury also has its uses. Mercury has special chemical properties and can form amalgam with many metals. In the extraction of precious metals such as gold and silver, mercury can be combined with the metals in the ore, and then distilled and other methods to evaporate the mercury, leaving pure metals. This technique was an important step in the ancient gold and silver smelting skills, helping craftsmen obtain pure gold and silver to make exquisite utensils.
The production of pigments also relies on hexagonal glossy mercury. The cinnabar pigments made from it are bright in color and will not fade for a long time. In ancient paintings, lacquer ware and other crafts, cinnabar was often used as paint to color, and the paintings and lacquers painted were gorgeous, and they were still dazzling after years. For example, the red of Dunhuang murals may have the power of pigments made of hexagonal gloss sand mercury, which still amazes viewers with the beauty of its colors after thousands of years.

If you want to make hexagonal photoacetyl, you need to do it in the ancient way. First take an appropriate amount of alcohol, put it in the clean kettle, slowly boil it over a slow fire, wait for it to boil slightly, and slowly add a specific agent. This agent needs to be prepared in proportion, and there must be no mistakes. In the meantime, the contents of the kettle should be stirred continuously to ensure uniformity.
Then, raise the heat, but not too much, causing it to boil. Looking at the change in color and texture, when the color turns light yellow and the texture is slightly thicker, the fire should be slightly reduced.
At this time, a specific gas is introduced and slowly passed into the kettle, and the flow rate of the gas needs to be precisely controlled. With the integration of the gas, the reaction in the kettle becomes more and more intense, so you need to pay close attention.
When the reaction is appropriate, cease fire to cool down, so that the contents of the kettle cool naturally. After that, purify it in a delicate way to remove impurities, and obtain pure hexagonal photoacetyl.
In this process, all the details are related to success or failure, and the heat, dosage, flow rate, time, etc. cannot be ignored. Only by proper handling can you get this good product. Although the ancient method is complicated, if you follow it, you will achieve success.

Hexagonal mercury sulfide, commonly known as cinnabar, is red and bright in color, and is often used by Dan's family. When storing and transporting both, pay attention to many accidents.
Mercury is active and volatile into mercury vapor, which is highly toxic. Therefore, although hexagonal mercury sulfide is more stable than mercury, it should not be ignored. When storing, the first weight should be sealed. It should be stored in a porcelain jar or glass bottle, and its mouth should be strictly sealed to prevent it from slowly decomposing due to excessive contact with air, and to avoid mercury escaping. Place in a cool and dry place away from heat and fire. Heat can promote its decomposition and increase the risk of mercury volatilization. And should not be co-stored with acids, alkalis and other substances to prevent chemical reactions from occurring, causing changes in composition and releasing mercury.
During transportation, the packaging must be solid and stable. Wrap the container with thick packaging material to prevent collision and damage. The person handling must wear protective equipment, such as gloves, masks, etc., to avoid direct contact. During transportation, drive carefully to avoid severe bumps and vibrations, and keep the packaging intact.
Although cinnabar is beautiful and has medicinal and other values, it contains mercury, which is related to life and health. Storage and transportation must be carried out in accordance with regulations, and no slack can be done to ensure people's safety and safety.
