Thiophene-2-acetic acid

The second acid of the leech, its use is great. In the Tao, there are three important reasons for its use.
One of them can break blood stasis. In human beings, if blood stasis is blocked, the blood will be damaged, and the disease will be born. Leech acid can enter the blood, dissipate the coagulation of blood stasis, and make the blood pass. The ancient ones, when they were hit by a fall, the blood stasis would gather in the blood, causing pain. Ninjas often use things containing leech acid. It is good to walk, which can penetrate deep into the blood stasis, dissipate blood stasis, and make the pain disappear. For example, in the "Compilation of Science", there are patients who suffer from blood stasis and pain in the lower limbs due to bleeding, and they are injured. They are mainly treated with leechoic acid. Every day, the blood stasis is scattered, the pain is big, and the walking is normal.
Second, it can be passed. For those who are injured, such as a river of people, the blood flows in it. If it is blocked, there will be a lot of blood loss, and there will be many diseases. Leechoic acid can dredge the blood and make the blood flow. In the middle of the disease, due to the paralysis, the loss of the limbs and the paralysis, the hemiplegia, numbness of the limbs, etc. The family often uses leechoic acid to add other drugs to pass the activity, help the blood flow in the limbs, and improve the deviation. There are many cases in this generation. With this rule of law, the disease can be cured in some patients, and the function of limbs can be restored, and the ability to take care of themselves can be increased.
Third, it can disinfect toxins. Poisonous pathogens, often cause pain. Leechinic acid has the power to dissolve toxins, and can dissipate the accumulation of toxins and pathogens. Such as the disease of surgical toxins, it starts at the beginning, and the toxin has not dissipated, and the pain is caused. Using leechinic acid externally or taking it can dissolve the toxin and calm the pain. "The collection of the experience of the family" said that to treat a patient's back pain and local pain, apply it with leechinic acid, and the poison will be eliminated for a long time.
In other words, it is the power of the Tao to break blood stasis, pass blood, disinfect poison, and treat diseases. It is important for those who care, and it is important to save people. Its use cannot be ignored.

The physical properties of calomel-2-acetic acid are as follows:
calomel, that is, mercury chloride ($Hg_2Cl_2 $), white color, weight, and variable properties. It is often a micro-powder. Its outer surface is white crystal or powder, and it smells bad. The density is high, 7.15 g/cm3, and it is soluble in water. Under normal conditions, it is almost insoluble in water, and the solubility is low. This property makes it impossible to disperse in water. Its melting temperature is high, 400 ° C, and when it is added to the temperature, it begins to melt into a liquid. It decomposes and evaporates mercury and other substances, so special care is required.
And acetic acid, which is often an acid, is also acetic acid. Under normal conditions, the transparent liquid has a strong and irritating smell. This smell is particularly strong and easy to identify. Its melting temperature is 16.6 ° C. At lower temperatures, it solidifies into ice and solidifies, so acetic acid is also glacial acetic acid. Boiling at 117.9 ° C, add 1 to 10 degrees Celsius and then boil and vaporize. Acetic acid is easily soluble in water and ethanol, etc., and water can be miscible in any ratio. It can form water molecules due to the presence of water-based groups in its molecules. In addition, the density of acetic acid is 1.05 g/cm3, which is slightly larger than that of water, and has a certain degree of resistance. It is slow to change in air.

What are the chemical properties of arsenic-2-acetic acid?
Arsenic is a highly toxic substance, and the chemical name is arsenic trioxide. Acetic acid, commonly known as acetic acid, is a common organic acid. Its chemical properties are unique and it is significantly manifested in many chemical reactions.
First, it is acidic. Acetic acid can partially ionize in water and release hydrogen ions, so it has the commonality of acids. It can react with active metals, such as zinc, to generate hydrogen and zinc acetate: $2CH_ {3} COOH + Zn = (CH_ {3} COO) _ {2} Zn + H_ {2}\ uparrow $. It can also neutralize with bases and react with sodium hydroxide to form sodium acetate and water: $CH_ {3} COOH + NaOH = CH_ {3} COONa + H_ {2} O $. It also reacts with basic oxides, like calcium oxide, to form calcium acetate and water: $2CH_ {3} COOH + CaO = (CH_ {3} COO) _ {2} Ca + H_ {2} O $.
Second, esterification can occur. When acetic acid and alcohol are catalyzed by concentrated sulfuric acid and heated, esters and water are formed. For example, it reacts with ethanol to form ethyl acetate and water. This reaction is a reversible reaction: $CH_ {3} COOH + C_ {2} H_ {5} OH\ underset {\ Delta} {\ overset {concentrated sulfuric acid} {\ rightleftharpoons}} CH_ {3} COOC_ {2} H_ {5} + H_ {2} O $. Esters often have a special aroma and are widely used in food, flavors and other fields.
Third, a substitution reaction can occur. In addition to esterification, the hydrogen atom on its methyl group can be replaced by other atoms or atomic groups under specific conditions. For example, under light or with a catalyst, it can undergo a substitution reaction with halogens to form halogenated acetic acid.
Fourth, a dehydration reaction can occur. Under specific catalyst and temperature conditions, two molecules of acetic acid can remove a molecule of water to form acetic anhydride: $2CH_ {3} COOH\ underset {specific conditions} {\ longrightarrow} (CH_ {3} CO) _ {2} O + H_ {2} O $. Acetic anhydride is an important intermediate in organic synthesis.

The preparation method of fuglutaric acid-2-acetic acid is covered by the following numbers.
First, glutaric anhydride and acetic anhydride are used as starting materials, and the reaction is carried out at a suitable temperature and reaction time. In this process, glutaric anhydride interacts with acetic anhydride, and glutaric acid-2-acetic acid can be obtained through specific chemical changes. It should be noted that the choice of catalyst is crucial. Its type, dosage and activity can have a significant impact on the reaction rate and product yield. Temperature also needs to be precisely controlled. If it is too high, side reactions will increase, and if it is too low, the reaction will be delayed or incomplete.
Second, starting from glutaric acid, it can first be chemically modified to convert some of its functional groups into suitable active groups, and then react with reagents containing acetic acid structures. This path requires in-depth understanding of the chemical properties of glutaric acid, careful design of modification steps and reaction conditions. In the meantime, the choice of reaction solvent is also quite important, and different solvents can affect the selectivity and rate of reaction.
Third, the method of biosynthesis is adopted. Find microorganisms with specific metabolic pathways, feed them with suitable substrates, and realize the synthesis of glutaric acid-2-acetic acid through enzymatic reactions in microorganisms. However, this method requires fine control over the culture conditions and metabolic regulation of microorganisms. The growth environment of microorganisms, such as temperature, pH value, nutrients, etc., needs to be strictly controlled to ensure the efficient synthesis of the target product.
Although the methods for preparing glutaric acid-2-acetic acid are different, they all need to be carefully studied on chemical principles, reaction conditions, etc., and carefully operated to achieve the desired effect.

Mercury is even more toxic, and its diacetamide needs to be stored and transported with caution.
Storage is essential, the first heavy container. It must be made of corrosion-resistant materials, such as special glassware or metal containers, and must be tightly sealed to prevent mercury gas from escaping. And the place where it is located should be cool and dry, protected from heat and moisture. Due to changes in temperature and humidity, or the unstable properties of mercury, and when the temperature is high, the mercury gas evaporates more quickly and becomes more harmful.
Furthermore, the storage place should be kept away from fire sources and strong oxidants. Mercury is prone to violent reactions when exposed to open flames or strong oxidants, resulting in a crisis. And it should be stored separately, not mixed with other things, to avoid chemical reactions, toxic changes or container damage.
As for transportation, protection is the key. The operator, in front of complete protective equipment, such as gas masks, protective clothing and gloves, must not let the skin come into contact with mercury, and do not absorb its volatile gas. The transport equipment must be stable and well sealed, and be careful to prevent bumps and collisions on the way to avoid damage to the container and leakage of mercury liquid.
Once there is a risk of leakage, cover it with sulfur powder as soon as possible. Mercury and sulfur are easily synthesized into mercury sulfide, which greatly reduces toxicity. And the site must be cleaned in time to avoid mercury residue. If you inadvertently inhale mercury gas, you should quickly move to a well-ventilated place and seek medical attention immediately.
All of these are things that should be kept in mind when storing and transporting mercury bisacetamide. A little negligence can cause countless consequences and cannot be ignored.
