Caramel, the best taste of ancient times, has a wide range of uses.
In the matter of diet, caramel is often a wonderful product for seasoning and adding color. In cooking, it can add the sweetness of food. In terms of cake making, adding caramel can make the texture of the cake more moist, and the taste is soft and sweet. For example, in making traditional moon cakes, caramel can help the skin to be golden and shiny, and the internal filling is also more sticky and sweet. In the process of winemaking, caramel is also useful. When making wine, it can provide sugar for yeast fermentation, which promotes more full fermentation, making the wine mellow and fragrant. Many of the ancient wines rely on the power of caramel to obtain a mellow taste.
In medicine, caramel also has certain effects. According to the ancient medical code, caramel is sweet and warm, and returns to the spleen, stomach, and lung meridians. It has the effect of nourishing the middle and nourishing qi, relieving pain urgently, and moisturizing the lungs and relieving cough. If a person's spleen and stomach are weak, and the abdominal cramps are acute and painful, caramel can be used as medicine to relieve the pain. For the symptoms of lung deficiency and cough, caramel can also moisturize the lungs and relieve cough. It is often combined with other medicinal materials to enhance the efficacy of medicine. Such as the classic Xiaojian Zhongtang, caramel is used as the king's medicine to warm the middle and replenish the deficiency, and the inside is slow and urgent, treating the symptoms of caramel deficiency and cold, liver and spleen disharmony.
Furthermore, among the folk customs, caramel also has In ancient times, such as the New Year's Day, caramel was made at home and eaten together as a family, implying the sweetness of life. And in sacrificial ceremonies, caramel was often made as an offering to feed the ancestors of the gods and spirits, expressing the heart of worship, and praying for well-being. Its bearing is not only the desire for appetite, but also the expectation and wish for a better life. Therefore, the use of caramel is related to diet, medicine, and folk customs, which is of great significance to the lives of the ancients.

Diborane is an inorganic compound. Its physical properties are quite interesting, as detailed below:
Looking at its physical state, under normal conditions, diborane is a colorless gas, light and floating in the air, like a ghost of nothingness, invisible and colorless but real existence. Its smell is unique, and it has a pungent smell. Although this smell is not as disgusting as rancid, it can also keenly stimulate people's olfactory senses and make people aware of its unique existence.
When it comes to melting and boiling points, the melting point of diborane is extremely low, about -165.5 ° C, just like being in an extremely cold environment, at such a low temperature, it can be condensed into a solid state. The boiling point is -92.5 ° C. When heated slightly, it jumps from liquid to gaseous state. It can be seen that the intermolecular force is weak, and it is easy to break free and evaporate.
In terms of density, the density of diborane is less than that of air, about 1.132 g/L (standard condition), so it can float upward in air, like a balloon.
In terms of solubility, diborane is slightly soluble in water, and it is difficult to dissolve in large quantities in water. When it meets water, it will chemically react to form boric acid and other substances, just like foreign matter that does not blend with water, which will cause wonderful changes when it enters the water.
In addition, diborane is highly flammable. When exposed to open flames or high temperatures in the air, it will burn violently. The flame is bright and releases a lot of heat. This is one of its important physical properties, which also makes it show unique potential and risks in the energy and chemical fields.
The physical properties of diborane may make it play a unique role in specific fields such as semiconductor manufacturing, organic synthesis, etc. However, due to its irritating and flammable properties, it is also necessary to use it with extreme caution and follow strict procedures to ensure safety.

When hiding, you need to pay attention to the following things.






















< It is to hide the appropriate shade, avoid direct light, and keep its purity.
When hiding it again, check it often. If you see that the container is damaged, or there is a sign of breath leakage, it must be easier to hold the container immediately and re-seal it. And record the time of hiding for a long time, know its timeliness, and prevent it from failing after the time limit.
Hide different pills, when choosing a place, avoiding miscellaneous things, avoiding light, and checking all things regularly, you should pay attention to it, so as to keep it in good condition for emergencies.

Diborane is an inorganic compound with unique and rich chemical properties.
Diborane reacts violently in contact with water to form boric acid and hydrogen. The reaction formula is: $B_ {2} H_ {6} + 6H_ {2} O = 2H_ {3} BO_ {3} + 6H_ {2} ↑ $. This reaction is very rapid, often accompanied by the release of heat, the produced hydrogen is flammable, and it is easy to explode in case of open flame or hot topic. Therefore, when operating diborane-containing systems, it is necessary to avoid contact with water.
Diborane can spontaneously ignite in air and react violently with oxygen to form diboron trioxide and water. The reaction formula is: $B_ {2} H_ {6} + 3O_ {2} = B_ {2} O_ {3} + 3H_ {2} O $. Due to its spontaneous flammability, diborane must take special measures during storage and transportation to prevent contact with air.
As a strong reducing agent, diborane can reduce many metal compounds. For example, some metal halides can be reduced to metal elements. In the field of organic synthesis, diborane is often used to reduce compounds containing carbon-carbon double bonds or triple bonds, realize hydrogenation reactions, and can also reduce carbonyl compounds, showing unique reduction properties.
In addition, diborane can react with ammonia to form boron-nitrogen hexacyclic compounds. This reaction enriches the variety of boron-containing nitrogen compounds and provides a new material basis for research in materials science and other fields.
Diborane is chemically active, and safety procedures must be strictly followed when using and handling to ensure the safety of personnel and the smooth progress of experiments or production.

In the "Tiangong Kaiwu", there is a system of caramel. The method is as follows:
All rice, wheat, millet, and millet can be used for it. First, take rice (malt) or wheat, boil it into a paste, spread it cold, one liter at the end of each cup, put it in a bucket of cold rice, stir well, pour it into a kettle, stir it with a wooden spoon, and wait for it to be warm like a human body, and place it in a warm place. When it is cooked at the beginning and rice, it must be harmonious with water and rice. Use five buckets of rice each time, and three stones of water. When rice is cooked into rice, when it is cooked, it must be cooked properly. If it is too ripe, it will become sticky lumps, and if it is too raw, it will not be saccharified.
When cooking, it must also be medium-cooked. If the fire is fierce, it will burn, and the taste will become bitter; if the fire is small, the saccharification will not be fast, and it will not be fully dissolved.
When the rice is warm, it is also important to warm it. Do not be too cold, and if it is cold, it will not saccharify; do not overheat, and if it is hot, it will rancid. Keep it warm like human skin, and place it in an unventilated place.
After a night, if it is ready, fry it in a kettle. When frying, slow down the heat and stir constantly to prevent burning. When it is thick, scoop it out, put it in a container, and when it is cold, caramel is ready. In this way, according to the ancient law, you can get delicious caramel.
