"Tiangong Kaiwu" has a saying: "Alum is necessary for the dyeing of hardware, and its categories are different. Lead alum, green alum, and gall alum each have their own properties and uses." Alum, there are many kinds and different properties.
In this word, gall alum and green alum, gall alum, that is, copper sulfate crystals, are blue in color and crystal clear, like a blue gem. Its nature is cold and poisonous. Green alum, also known as ferrous sulfate heptahydrate, is light green in color, like the tenderness of new leaves. It is also cold in nature and has the nature of convergence.
In ancient times, gall alum was mostly used by alchemists, and it was also used in dyeing workshops to help dye objects and color, with a bright color. However, its toxicity should not be underestimated, and accidental ingestion can easily cause severe abdominal pain, even endangering life. Green alum is also widely used in medicine, which can treat sores and diseases, as well as the disease of blood deficiency and yellowing; in industry, it can be used to make iron salts, which are raw materials for many processes.
Alum two substances, although they are all important in chemical industry, are poisonous in nature, use them with caution; those who have convergence, apply them wisely. Only by clarifying its nature can we make good use of it to avoid disasters. This is the wisdom of the ancients in using alum, and it should also be observed by future generations.

1% 2C3 refers to "boron and dioxane", and 4 refers to "alum". Its main uses are as follows:
Boron is very important in the art of alchemy. Borax is often used as a flux to help other substances melt, making the refining process of medicinal pills smoother. In the casting of utensils, especially fine metal casting, boron can optimize the properties of metals, increase their hardness and toughness, and make the casting more durable. In physicians, boron has the effects of clearing away heat and eliminating phlegm, detoxifying and antiseptic, and can treat sores in the mouth and tongue, sore throat, etc.
Dioxane, although it has no current chemical understanding in ancient times, may be formed accidentally in the refining or special processes of some substances. Its nature is poisonous, if accidentally touched or ingested, it will be harmful to the human body. However, the exact harm may not be known at that time, and only occasionally abnormal reactions are detected when handling special materials or performing strange refining.
Alum has a wide variety of uses. Green alum, which can be used as medicine, has the ability to dry and wet insects, replenish blood and eliminate accumulation, detoxify and restrain sores, and is used by doctors to treat scabies, anemia and other diseases. In dyeing workshops, green alum can be used as a mordant to help fabric color better and make the color bright and lasting. Blue alum, that is, copper sulfate crystals, is used in agriculture to prepare Bordeaux liquid to prevent crop diseases and ensure crops. It is also used to extract copper and is important in mining and metallurgy. Alum, often used as a water purifier to settle impurities in water and obtain clean water. In food processing, it has been used to shape or keep food fresh, but the dosage should be cautious. In the printing and dyeing industry, it can be used as a mordant to help dyes fix fabrics.

To prepare "1,3-naphthalene dioxazole, 4-nitrile", the synthesis method is as follows:
First take an appropriate amount of naphthol as the starting material, in an appropriate container, in an alkali-catalyzed environment, and react with halogenated acetate esters. This step aims to introduce ester groups to generate corresponding naphthoxy acetate derivatives. During the reaction, the temperature, the amount of base and the proportion of reactants need to be precisely controlled. The temperature should be maintained at about [X] ° C, the amount of base is about [X] times the amount of naphthol substance, and the ratio of halogenated acetate to naphthol substance is [X].
The obtained naphthoxy acetate derivatives are hydrolyzed to convert the ester group into a carboxyl group. This process selects a suitable basic aqueous solution, such as sodium hydroxide solution, and reacts under heating conditions. The temperature is controlled at [X] ° C, and the reaction time is about [X] hours, which promotes the full hydrolysis.
The hydrolysis products are acidified to adjust the pH value of the solution to a suitable range, so that the carboxyl group exists in the form of a free acid, and then cyclization is carried out under the action of a dehydrating agent. The dehydrating agent can be selected as phosphorus pentoxide, etc. The reaction temperature is raised to [X] ° C, so as to obtain naphthalene oxazolone intermediates.
Subsequently, the naphthalene oxazolone intermediate is reacted with a suitable nitrile reagent, such as potassium cyanide (safety should be paid attention to when using), in a suitable organic solvent, at a certain temperature and under the action of a catalyst, the introduction of the nitrile group is achieved. The reaction temperature is controlled at [X] ° C, and the catalyst dosage is [X]% of the amount of intermediate material. Finally, 1,3-naphthalene oxazole and 4-nitrile are successfully synthesized. The entire synthesis process requires fine control of the reaction conditions at each step, and strict separation and purification of the product to ensure high yield and purity.

In storage and transportation, all matters need to be treated with caution. When storing, the first location should be selected. The chosen place should be flat and solid, and the terrain should be high and dry to prevent moisture and moisturization. And it should be convenient for transportation, which is convenient for the entry and exit of goods. The construction of the warehouse must also be appropriate, the materials used are sturdy, and the space layout is reasonable, so as to facilitate the stacking and management of goods.
Furthermore, the storage and arrangement of goods should be clear. The same kind of gathering, numbering registration, detailed category, quantity, and entry and exit dates, so that when they can be used, they can be used quickly and correctly. At the same time, it is necessary to pay attention to the characteristics of the goods. If it is perishable and flammable, special warehouses should be set up, and strict protection should be taken. Do not mix with other things to avoid disasters.
When transporting, the choice of tools is very critical. According to the weight, size, distance and proximity of the goods, choose the appropriate vehicle and ship. During the journey, drive slowly, avoid sudden brakes and crashes, and prevent damage to the goods. And pay attention to changes in the weather, in case of wind, rain and lightning, when looking for a place to temporarily avoid to ensure the safety of the goods.
When handing over, both parties need to check the list in detail, check the number, and see if its appearance is damaged. If there is any mistake, immediately clarify the responsibility and record it for the record. In this way, all things in storage and transportation are done with caution, so as to ensure that the goods are complete and everything goes smoothly.

Today, there are 1 stone and 3 buckets of grain and two evils, and the price of 4 buckets. What is the price of the market? This is a question about the price of grain. If you want to understand its price, you should consider the government at that time, the situation of the city, the amount of production and many other factors.
The ancient government had a great influence on the control of grain prices. If in a good year, the government or the farmers are encouraged to accumulate grain, so that the grain in the city is sufficient, and the price may drop steadily; if in a disaster year, the government or the warehouse is opened for relief, or the ban on commerce is relaxed, and grain is brought into the market, the disaster will be heavy and the grain will be scarce, and the price may rise. The government's taxes and policies are all related to the price of grain. If the tax is heavy, the cost of agriculture will increase, and the price will be higher; if the official sells it, if the price is high, it will be sold, and if the price is low, it will be purchased, so that the price of grain will be flat.
The situation of the city is related to supply and demand. If there are many people in need of grain at a time, such as war and chaos, the people are hoarding grain, and the supply is insufficient, and the price will rise; if the four sides are peaceful, the people's needs will be stable, the supply will be orderly, and the price will be stable. Moreover, the manipulation of merchants and the rules of behavior also affect the price of grain. Merchants hoard grain and sell it reluctantly, driving up the market price; there are rules on pricing, limiting the price of grain.
The In a good year, the grain is abundant, the supply exceeds the demand, and the price is low; in a disaster year, the grain is sorry, the supply is not enough, and the price will be high. The fertility of the land, the pros and cons of planting, the diligence of farming, and the time and profit of the sky are all related to the yield. If the land is fertile, the good seeds are widely planted, the farming is diligent, and the rain is smooth, the grain will be abundant; otherwise, the grain will be sorry.
However, only one stone, 3 buckets of millet and two evils are said, and the price of 4 buckets is not known at the time and in the place, so it is difficult to determine the price. Or you need to study the history again, and check the political conditions, market conditions, output and other conditions at that time in detail, before
