What are the main uses of sodium 1-pentane sulfonate?
Poison wine, soaked in poisonous feathers, contains highly toxic. Its main use in ancient times was to give death or assassinate.
In the court, emperors wanted to get rid of people who were a threat to the regime, and often gave poisoned wine. If the power of some powerful ministers grew and posed a challenge to the imperial power, the emperor would use this method to stabilize his rule. According to "The Biography of Huo Guang in Hanshu", when Emperor Xuanji of the Han Dynasty, Huo Guang's wife apparently made his daughter an empress. While Empress Xu was weak in childbirth, she bribed the female doctor Chunyu Yan to poison her medicine and kill Empress Xu. This is for the purpose of competing for favor in the harem and continuing the family power.
In political struggles, poisoned wine was also frequently used by all parties in order to compete for power and profit. During the Northern and Southern Dynasties, the regime changed frequently, and the forces of all parties were contentious. Some members of the royal family or politicians would secretly use poisoned wine to murder their opponents in order to eliminate dissidents. If a prince covets the throne, he may send someone to send poisoned wine to other brothers who are eligible to inherit the throne to prevent future troubles and remove obstacles to the throne.
Although it is rare among the people, there are occasional people who use poisoned wine due to deep hatred or financial murder. If a rich household is coveted by others, the bad guys try to put poisoned wine in their diet to seize the property. However, due to the rarity of poisoned birds and the control of the court, it is not easy for the people to obtain poisoned wine. Such situations are relatively rare compared with the court and political struggles.
What are the precautions for storing sodium 1-pentane sulfonate?
First, it is necessary to keep an eye on the things that need to be hidden. This kind of treasure needs to be dry and good. If the tide in the ground is not good, the acid of the tiger will be easily rotten, and it will cause it to be damaged. And if the communication is not good, the taste will gather, or other troubles will occur. Like those who hid treasures in ancient times, they must be highly dry and clear. The same is true.
Second, be careful to isolate them. Tiger acid and other things, especially those that are flammable and explosive, must not be mixed. Because of its special nature, it is difficult to hide or attract things that are not suitable. Those who were accidentally mixed in in the past will cause an explosion and lose weight.
The third is to hide it. The sour nature of the tiger should not be known to others. The place where it is hidden should be kept secret. Those who are not in charge should not be easy to explore. Because it is either secret or dangerous, if it is not obtained by others, it may cause trouble.
Fourth, it is difficult to find. Regularly check the acid of the hidden tiger, and check it. There are signs of damage and damage. If there is a problem, quickly set it up. Such as those who are good, often check the color of their fur and food to know their health. The same is true.
Fifth, the hidden treasure. The hidden treasure, the amount, date, and so on. It depends on whether it is taken or checked in the future. Such as the history of the historian, the beginning and end of the Ming Dynasty, and there is no distortion.
Tibetan tiger is sour, pay attention to the situation, so as to ensure its safety and use it.
What are the physical and chemical properties of sodium 1-pentane sulfonate?
For those who are sour, the nature is special and special. Its color is often in the shape of the water, just like the autumn water contains light, and there is a clear flow, which is comparable to the uncommon things. In addition, it feels like the ground is smooth, as smooth as grease, but there is no lack of the nature of the water, just like the beauty of softness.
Smell it, the breath is light and quiet, like the fragrance of the empty valley,, refreshing, making people's hearts and minds. And under the light, it can be shimmering, like the stars, Color, amazing.
Furthermore, its transformation is special. When encountering the melting of water, it is as if there is a glow in the water, and the color of the water also melts slightly. If it does not melt, it will increase the clarity of the water. If it is burned with fire, it will rise up, and it will be a pale purple color, and it will rise up, and the fragrance will be diffuse. And this thing will not melt without fire, and its form will exist, which can be reduced to its nature.
It is also placed in the ordinary material, which can be more integrated, and the harmony will make the force more mellow and peaceful, and increase its effectiveness. In the path of alchemy, it is also wonderful, which can help the color of alchemy to be correct, and the quality is high, so it is important to the family of alchemy. Its unique characteristics are the wonder of the creation of heaven and earth, and cannot be known without careful investigation.
What is the synthesis method of sodium 1-pentane sulfonate?
To prepare 1-bromobutyric anhydride, it can be obtained by co-heating the acyl halide with the carboxylate according to the ancient method.
First take 1-bromobutyric acid, add sulfite chloride, heat, and combine the two phases. In this reaction, sulfite chloride interacts with the hydroxyl group of 1-bromobutyric acid to form 1-bromobutyric chloride with a chlorohydroxy group, and at the same time escapes sulfur dioxide and hydrogen chloride gas. The chemical principle is that the sulfur in sulfite chloride is nucleophilic and can attack the oxygen of the hydroxyl group, and the subsequent bond rearrangement and cracking result in this product.
1-bromobutyryl chloride is obtained, and the sodium salt of 1-bromobutyrate is taken. This salt can be made to neutralize 1-bromobutyric acid with an appropriate amount of base, and then obtained by evaporation and crystallization. 1-bromobutyryl chloride and 1-bromobutyrate sodium salt are co-placed in a reactor and heated slowly. At this time, the carbonyl carbon of the acyl chloride is electrophilic, and the oxygen negative ion of the carboxylate is nucleophilic. The oxygen negative ion attacks the carbonyl carbon to form an intermediate. After intramolecular rearrangement, the monohalogen ion is removed, and 1-bromobutyric anhydride is obtained.
When operating, pay attention to everything. The equipment used must be clean and dry to prevent moisture from hydrolyzing the acid chloride. The reaction temperature should be slowly raised and stabilized. If it is too high, the product may decompose, and if it is too low, the reaction will be slow. And when the gas escapes, it should be properly collected and handled to avoid polluting the environment and harming the body.
In this way, according to the above method, 1-bromobutyric anhydride can be obtained by following the rules.
What are the safety precautions for sodium 1-pentane sulfonate during use?
One of them is the safety of holding on to the ashes. Holding on to the ashes will make the grip of the hand stable. If the grip is not firm, the hammer will easily be thrown away by the hand, hurting people and objects, and causing chaos. Therefore, it is necessary to check whether the handle is greasy or damaged. If there is one, it should be repaired or replaced quickly. Make sure to hold it firmly before you can act.
Second, be careful when swinging. When swinging the hammer, you must first check the surroundings and see if there are others involved. If you use force rashly, the hammer will fall without an eye, hurting the innocent, and the crime will be great. And when exerting force, it should follow the right path and not be deflected, otherwise the force will not be used, and it will shock itself, causing injuries to the wrist and elbow.
Third, it is appropriate to store it. Use the ash to pick it up, and do not dispose of it at will. Or put it on a high place, accidentally fall, and hurt the past; or put it in the passage, tripping people and falling. When looking for a safe place, such as a special frame and box, properly place it for the next use, and also ensure the orderly safety of the place.
Fourth, the diligence of inspection. Always check whether the hammer head of the ash pick is tightly combined with the handle of the hammer. If it is loose, when the hammer strikes, the hammer head comes out, like a runaway horse, the damage is endless. Also look at whether the hammer head has cracks, missing corners, and whether the hammer handle is rotten or insect-eaten. Once found, repair or update it immediately. Don't take chances and cause a big disaster.
Such precautions are all essential for safety when using ash peeling. Practitioners must not ignore them. They should keep them in mind and follow them carefully to be safe.
