1,6-Diethyl ether acetone, what is it called in ancient times, and what is its use? This is an organic compound. Looking at "Tiangong Kaiwu", although it is not described directly, it can be deduced from the principles of its chemical industry.
In ancient chemical industry, it is involved in pottery, smelting, brewing, and dyeing. 1,6-Diethyl ether acetone has unique chemical properties, or can be used for the dissolution of specific materials. In the art of dyeing, fabric coloring requires an auxiliary agent to make the pigment uniform and fixed. If this material has good solubility, the pigment can be dissolved into a uniform liquid, which helps the pigment penetrate the fabric fibers, so that the dyeing is uniform and firm.
It is also like the ancient fragrance preparation. Fragrances may be solid and require solvent to dissolve into a liquid, which is easy to prepare and use. If 1,6-diethyl ether acetone has a suitable odor and stable chemical properties, it can be a fragrance solvent to help flavors fuse, showing a unique fragrance.
Re-talk the ancient medicine. In the process of pharmacy, extracting the active ingredients of medicinal materials may require solvents. If this substance has good solubility to some ingredients and is not harmful, it can be used for extraction to make pill powder and paste pills. However, the ancients were cautious in their medication and must carefully observe its properties before they dare to use it.
Although "Tiangong Kaiwu" did not specify 1,6-diethyl ether acetone, according to its chemical wisdom, this substance may be available in dyeing, fragrance, medicine and other industries, adding color to the lives of the ancients.

1% 2C6-dibromoethane is a colorless and transparent heavy liquid with many physical properties. Its appearance is clear and transparent, often stored in a liquid state under room temperature and pressure, and the smell is slightly sweet. However, behind the sweet fragrance, there is a hidden danger of toxicity.
Looking at its density, it is heavier than water, about 2.17g/cm ³. If it is co-located with water, it will sink to the bottom of the water. Its boiling point is 131.4 ° C, and it needs a higher temperature to boil into a gaseous state; its melting point is 9.3 ° C, and it condenses into a solid state at a slightly lower temperature.
1% 2C6-dibromoethane is insoluble in water, but it is easily soluble in organic solvents such as ethanol, ether, and chloroform. This solubility makes it a good solvent or reaction intermediate in organic synthesis and other fields. However, due to its high toxicity, extreme caution is required when using it. Its vapor is heavier than air and can diffuse to a considerable distance at a lower place. In case of open flame and high heat energy, it can cause combustion and explosion, which poses a great safety hazard.
This substance is highly toxic and seriously harmful to the environment and human body. In the past, it was used as an additive for fumigants and gasoline shock-resistant agents. Later, due to the deepening awareness of toxicity, many applications have been restricted or abandoned. In industrial production and experimental operations, exposure to 1% 2C6-dibromoethane must follow strict safety procedures to prevent poisoning and accidents.

The chemical properties of 1,6-dibromoethane are still stable. This compound contains bromine atom di, and the reaction with many common reagents requires specific conditions to occur.
In terms of thermal stability, 1,6-dibromoethane is not easily decomposed in a general heating environment without catalysts or special reactants. Although the carbon-bromine bond has a certain polarity, its bond energy is sufficient to maintain the stability of the molecule at room temperature and under moderate heating.
In the redox reaction, 1,6-dibromoethane is not easily oxidized or reduced spontaneously. It is neither a strong oxidizing agent nor a strong reducing agent, and it is difficult to change significantly in ordinary redox systems.
When encountering a nucleophilic reagent, 1,6-dibromoethane can perform a nucleophilic substitution reaction. However, this reaction requires a certain activity of the nucleophilic reagent and is mostly carried out under suitable solvent and temperature conditions. For example, with sodium alcohol in an alcohol solution, ether compounds can be formed; with sodium cyanide in an appropriate solvent, nitriles can be converted.
Under the action of light or a free radical initiator, 1,6-dibromoethane can participate in free radical reactions. However, under normal circumstances, free radical reactions are difficult to occur spontaneously without such special initiation conditions.
In summary, the chemical properties of 1,6-dibromoethane are relatively stable, and specific conditions are required to cause significant chemical reactions. In general environments and common chemical reaction scenarios, it can maintain a relatively stable state.

The preparation method of 1,6-dibromoethane is made of ethanol and hydrogen bromide as raw materials through specific reaction steps.
The method is as follows: First take an appropriate amount of ethanol and place it in a clean flask. Ethanol, as an organic compound, also has special chemical properties. Next, slowly inject hydrogen bromide gas. Hydrogen bromide is also an important chemical reagent. When the two meet, a substitution reaction occurs.
In this reaction, the hydroxyl group of ethanol (-OH) interacts with the bromine atom (Br) of hydrogen bromide, the hydroxyl group leaves, and the bromine atom replaces it to generate 1,6-dibromoethane. This reaction needs to be carried out under suitable temperature and catalyst conditions to ensure the smooth and efficient reaction.
Temperature control is crucial. Excessive temperature, or side reactions occur, affect the purity of the product; too low temperature, the reaction rate is slow and takes a long time. Therefore, the reaction temperature is often precisely regulated by means of water bath heating.
The choice of catalyst cannot be ignored. A suitable catalyst can reduce the activation energy of the reaction and accelerate the process of the reaction. Common catalysts include sulfuric acid. Sulfuric acid in the reaction can promote the ionization of ethanol and hydrogen bromide, making the two more prone to react. < Br >
After the reaction is completed, the product is often mixed with unreacted raw materials and by-products. At this time, it needs to be separated and purified by distillation, extraction, etc., to obtain pure 1,6-dibromoethane. The distillation method uses the difference in the boiling point of each substance to separate 1,6-dibromoethane from other substances; the extraction method is based on the different solubility of 1,6-dibromoethane in different solvents. In this way, a good method for making 1,6-dibromoethane is obtained.

When storing and transporting 1,6-dibromoethane, it is necessary to pay attention to many key matters.
First, when storing, choose a cool and well-ventilated warehouse. This is because 1,6-dibromoethane is volatile to a certain extent. High temperature or poor ventilation can easily cause it to evaporate and accumulate, or risk safety. The temperature of the warehouse should be strictly controlled, not too high, to prevent the substance from accelerating volatilization due to rising temperature, or even triggering other chemical reactions. At the same time, it is necessary to keep away from fire and heat sources, both of which may cause the combustion of 1,6-dibromoethane. Because it is an organic compound, it is flammable.
Second, it should be stored separately from oxidants and alkalis, and should not be stored together. The chemical properties of 1,6-dibromoethane are relatively active. When it comes into contact with oxidants, it is easy to trigger oxidation reactions, or cause violent combustion or even explosion; when it encounters alkali substances, chemical reactions may also occur, affecting its stability and quality.
Third, when transporting, the transport vehicle must have good ventilation equipment. This can effectively disperse the volatile gas of 1,6-dibromoethane during transportation, avoid excessive gas concentration in the car, and reduce safety risks. And the vehicle should be driven according to the specified route, do not stop in densely populated areas and downtown areas. This is to avoid unexpected situations such as leakage, which will cause serious harm to many people.
Fourth, the handling process needs to be handled lightly, and it must not be operated brutally. Most of the containers stored in 1,6-dibromoethane are made of glass or metal. Brutal handling can easily cause damage to the container, resulting in leakage. Once leaked, it will not only cause damage to the substance, but also cause pollution to the surrounding environment. If not handled properly, it may also endanger personal safety.
