Changsan (Sanxiang methylnaphthalene acetic anhydride), its physical properties are as follows:
Changsan color state, under room temperature, mostly in the shape of white to light yellow crystalline powder, it looks quite delicate, like frost and snow covered lightly, under the sunlight, occasionally shimmering, like broken jade. Its texture is relatively dry and delicate to the touch. If you twist it with your fingers, it is like fine sand sliding between your fingers, but it is softer.
As for its smell, it is close to a light smell, with a slight but slightly pungent smell. It is not pungent and intolerable, but it is also clear and discernible. This smell is like the traces of precipitation over time. Although it is light, it is unique and fascinating.
The melting point of Changsan is about [X] degrees Celsius. At this temperature, the crystals of the original solid state gradually melt into a liquid state, like spring snow meeting the warm sun, and the shape changes, like an illusion, witnessing the miraculous transformation of matter. Its boiling point is around [X] degrees Celsius. When the temperature rises to this point, the liquid state turns into a curling gaseous state, merges into the invisible air, and disappears from view, leaving only the unique smell, which seems to tell its past existence.
Changsan in solubility, in organic solvents, such as ethanol, acetone, etc., can be quite compatible, just like fish get water, can quickly disperse in it, forming a uniform mixing system; However, in water, its solubility is not good, put into water, more like fine grains of sand sinking in the bottom of the water, although stirred, it is difficult to integrate with the water, seems to have water repellency, showing its unique personality.
This is the physical properties of Changsan (Sanxiang methylnaphthalene acetic anhydride). Looking at it, smelling it, and exploring it, all have wonders, which are amazing and changeable.

For Changsan (Sanyo Acetylsalicylic Acid), many matters need to be paid attention to during storage and transportation.
When storing, the temperature and humidity of the environment should be the first priority. It should be placed in a cool, dry and well-ventilated place. If it is in a humid place, moisture is easy to penetrate, causing its characters to mutate and its efficacy to be reduced. The temperature should not be too high. If it is overheated, it may decompose and deteriorate the drug ingredients.
Furthermore, light is also the key. It should be avoided in a place protected from light. If the light is too strong, it is easy to cause photochemical reactions, change the chemical structure, and affect the medicinal power.
During transportation, it is important to be stable. Make sure that the packaging is intact to avoid bumps and collisions to prevent damage to the drug. When handling, you should also handle it with care, and do not act rudely, causing the package to break and the medicine to be exposed.
And the means of transportation should be clean, hygienic, and free of odor. If the transportation environment is unclean, or contaminated with impurities, odors, stains the medicine, and endangers the safety of the medicine.
Furthermore, it is necessary to operate in strict accordance with the drug transportation specifications. Follow the established procedures and standards to ensure the quality of the medicine throughout the transportation, and provide safe and effective Changsan (Sanyo Acetylsalicylic Acid) for the user.

The method of refining Changsan (Sanjiang Acetylsalicylic Anhydride) is quite complicated, and it needs to be refined by the ancient method and suitable for today's ingenuity.
First take an appropriate amount of willow skin and finely grind it. The willow skin contains the quality of natural salicylic acid, which is the basis for making Changsan. In the kettle, add an appropriate amount of water and cook slowly over a slow fire. The water is the medium for the medicine, and the fire is the cause of its change. Wait for it to boil and the medicinal taste comes out, and filter it with a cloth to obtain a clear liquid. Although this liquid contains medicinal properties, it is not pure and needs to be remade.
Prepare another aluminium stone, calcined until it is red and turned into a fine powder. The aluminium stone can help impurities settle. Slowly add the aluminium powder into the willow skin serum, stir it well, and let the tablet stand. When there is precipitation at the bottom, re-filter it, and the liquid will be clear.
Then, take an appropriate amount of acetic anhydride and put it into the purifier. Acetic anhydride is an essential agent for the synthesis of Changsan. Add the above-mentioned clear liquid to acetic anhydride gradually, and heat it over a low heat at the same time, and keep stirring. The temperature of the fire must be moderate. If it is too hot, the medicine will be damaged, and if it is too cold, it will not be combined. Stir to make the two fully blend. After a while, white crystals will gradually emerge, which is the beginning of Changsan.
Rinse the crystals with cold water to remove their impurities. Then use the filter paper to absorb the water, place it in a cool and dry place, and wait for it to dry completely. At this time, the third length has already been made, but it is still necessary to carefully check its quality, observe its color, smell its taste, and test its properties to meet the required standards.
The whole process of refining, you need to abide by the law, and there must be no mistakes. The control of heat, the accuracy of dosage, and the order of operation are all about success or failure. The ancient method is used today, and it should also be adapted to the times and continuously refined to obtain good products.

"Tiangong Kaiwu" cloud: Changsan (glyceryl trioleate), in the process of use, hides all safety risks.
First, the risk of ignition and explosion. Changsan is flammable, and if it encounters an open flame or a hot topic, it is easy to ignite, and even cause an explosion. During storage and transportation, if it is not handled properly, such as the environment temperature and humidity out of control, or the accumulation of static electricity, once it touches the source of fire, it will immediately ignite a raging fire, causing harm to the surroundings.
Second, it is dangerous to health. Although it is non-toxic, if it is exposed for a long time, or accidentally ingested or inhaled, it is also harmful to health. Percutaneous absorption can cause skin allergies, itching, redness and swelling; it enters the eyes, irritates the eyes, and damages the vision. If swallowed by mistake, it can cause gastrointestinal discomfort, nausea, vomiting, abdominal pain and other symptoms. As for inhaling its volatile gas, or affecting breathing, chest tightness and asthma will also occur.
Third, environmental disasters. If Changsan flows into the environment, it will be decomposed by microorganisms, or produce greenhouse gases, which will add to the greenhouse effect. And it is difficult to degrade in water or soil, accumulating in the ecology and breaking the ecological balance. If aquatic organisms come into contact with or are poisoned, their growth and reproduction will be disturbed, which will then affect the entire aquatic ecosystem.
Therefore, when using, storing and transporting Changsan, it is necessary to take precautions to avoid risks and ensure people's safety, safety and well-being.
