The main uses of thyrophenol and menthol are related to many aspects of medical treatment and daily use.
In the field of medical treatment, it has significant medicinal effects. Thyrophenol has antibacterial and anti-inflammatory properties. It can be used to treat skin diseases, such as ringworm diseases, etc., can inhibit the growth of fungi, relieve skin itching, redness and swelling. In the oral field, it is also often used. It can be added to toothpaste and mouthwash to help prevent oral inflammation, freshen breath, and maintain a healthy environment in the mouth. Menthol has the effect of cooling, relieving pain, and relieving itching. It is commonly used in external ointments and applied to the skin to reduce itching caused by mosquito bites. It also has the effect of relieving pain for minor burns and abrasions. And menthol can stimulate the cold receptors of the nerve endings of the skin, causing the skin to feel cool. It is often used to relieve headaches, dizziness, and smell the smell of menthol, which can refresh the mind and refresh the spirit.
In terms of daily needs, it is very popular in the fragrance industry. Thyme has a unique aroma and can be added to perfumes and aromatherapy products, giving the product a different fragrance and creating an elegant atmosphere. The cool aroma of menthol is common in many daily necessities such as body wash and shampoo. It can bring a refreshing feeling and enhance the pleasant experience of use.
From this perspective, both thyme and menthol play an indispensable role in medical and daily use, and contribute a lot to people's health and quality of life.

Saltpeter, sulfur, and charcoal are the main components of gunpowder, each of which has unique physical properties.
Saltpeter, that is, potassium nitrate, is mostly colorless and transparent orthorhombic or cubic crystal particles or white powder. It is brittle, with a density of about 2.109 g/cm3, and is easily soluble in water. The solubility increases significantly with increasing temperature. Heating to 334 ° C will decompose and release oxygen. This property makes it play an important role in the reaction of gunpowder. It can provide the required oxygen for combustion and promote violent oxidation reactions.
Sulfur, usually a light yellow brittle crystal or powder, has a special odor. The density is about 2.07 g/cm3, insoluble in water, slightly soluble in ethanol, ether, and easily soluble in carbon disulfide. Its melting point is low, about 119 ° C, and when heated to 160 ° C, it turns into a sticky liquid. In gunpowder, sulfur can not only be used as a fuel to improve the combustion efficiency of gunpowder, but also reduce the ignition point of gunpowder, making it easier to ignite.
Charcoal is generally a black porous solid, mainly composed of carbon elements, and also contains a small amount of hydrogen, oxygen, nitrogen and ash. Charcoal is light, less dense than water, and loose and porous. This structure makes its surface area large, and it is fully in contact with oxygen, which is conducive to combustion. Its ignition point is relatively low. It is used as the main fuel in gunpowder, releasing a lot of heat during combustion, providing energy for gunpowder explosion.
The three are mixed in a certain proportion and made into gunpowder through a specific process. Saltpeter supplies oxygen, sulfur supports combustion and reduces ignition point, and charcoal provides fuel, which cooperate with each other to give gunpowder strong explosive performance, and play a significant role in military, civilian and many other fields.

On a certain day, I studied the properties of various things in a workshop. During this time, I asked: "Are the chemical properties of caustic soda, soda ash, borax, and boric acid stable?" I thought for a long time, but I said:
For caustic soda, sodium hydroxide is also strong alkaline, highly soluble in water, and exothermic when dissolved. Its nature is active, and it can quickly neutralize with acid, generating salt and water. Exposed to air, it can absorb moisture and react with carbon dioxide, so it needs to be sealed and stored, and its stability is not good.
Soda ash is sodium carbonate. Although it is a salt, it is alkaline. It is relatively stable at room temperature, but when it encounters strong acid, it reacts violently and releases carbon dioxide. When it is high temperature, it will also decompose. It can be seen that its stability is not absolute, and it changes under specific conditions.
Borax, commonly known as sodium tetraborate, can slowly weathering in air. Its aqueous solution is weakly alkaline, and at a certain temperature and humidity, it may change the content of crystalline water. The stability is affected by environmental factors.
Boric acid is a weak acid and has the ability to disinfect and prevent corrosion. It is relatively stable at room temperature, but it can lose water when heated, and gradually change to metaboric acid. When it encounters strong alkali, a neutralization reaction can occur, and its stability is also limited.
In summary, the chemical stability of these substances is not static, and is affected by many factors such as temperature, humidity, pH, etc. Under different conditions, their performance varies. When used, it should be carefully considered and properly disposed of according to its characteristics to obtain safe and effective results.

The method of making sugar paste and vinegar paste needs to be carefully studied.
The first ingredient needs to be carefully selected. For those who are new and fat, their taste is spicy and mellow, which can warm up the body; for those who are fresh and fat, the taste can be cold and warm; for those who are sweet, sugar can be used in the ground, and the color can be crystalline. Vinegar should not be ignored. It should be used in good years. Its fragrance is depressing, and the sour taste is sour. It can give the paste a special taste.
Wash and peel first, cut into thin slices, and use a stone mortar to overflow the juice slightly. This can help the taste to be easier to put away. Then take a cup of rice, set it on a slow fire, pour in a small amount of water, wait for the water to rise slightly, put in the good cup of rice, and cook slowly for half a moment, so that the essence of the cup is melted in the water.
Add sugar in proportion, and mix well to prevent the sugar from sticking to the caramel. The sugar is yellow, golden in color, clear like amber. Here, heat well until a slight fire, then slowly add vinegar, add more vinegar, add vinegar, vinegar into the pot, and the fragrance will spread.
Boil the pot, you need to keep your eyes open, and check the thickness of the paste. Dip the paste in bamboo chopsticks and drop it in cold water. If the paste does not disperse, but condenses on the water surface, like pearl jade, the heat is just right. Then cease fire and wait for it to be naturally cold.
When it is cold, the paste should be thick and bright in color. Hold it in a pottery jar, seal it and keep it dry. This sugar paste and vinegar paste can not only taste, but also have the effect of life. It is a must-have product at home.

When storing cholic acid, the environment is the most important. It should be hidden in a cool, dry and ventilated place, away from direct sunlight. Due to the intensity of sunlight, or the variation of its ingredients, its efficacy will be reduced. If it is in a humid place, it is prone to mildew and damage its quality. Furthermore, temperature is also important. If it is overheated, the acid bile will be easily irritable and the medicinal power will be dissipated; if it is too cold, it will be afraid of condensation and affect the use.
As for the time of transportation, there are also many things to pay attention to. Handling workers need to be handled with care and avoid rough actions. When transporting, it is advisable to control its duration, and not to stay on the road for a long time, so as to avoid changes due to the duration.
The environment in which it is transported also needs to be appropriate. It should not be transported with filth or odor, for fear of being stained by it and damaging its purity. If it is transported for a long time, after arriving at the place, it should be inspected quickly to see if it is damaged or deteriorated.
When storing and transporting food incense, bile and acid, it is all about its quality and efficacy, and must not be ignored. It must be based on its nature, carefully choose the storage place, and properly transport it, so as to have all its functions and ensure its good effect.
