2-Diazo-1-Naphthol-5-Sulfonic Acid Sodium Salt

What are the chemical properties of 2-% dialkane-1-naphthalene-anthracene-5-phenolic acid and cobalt oxime? These are all extraordinary things. Although they are not described in detail in Tiangong Kaiwu, their properties can be seen today.
2-% dialkane, which is a genus of alkanes, has the commonality of alkanes. Its chemical properties are relatively stable, and it is difficult to react with strong acids, strong bases, and strong oxidizing agents at room temperature and pressure. If methane does not react with common reagents such as concentrated sulfuric acid and sodium hydroxide, the same is true for 2-% dialkane. Under light conditions, it can react with halogens. In case of chlorine gas, when lit, chlorine atoms replace their hydrogen atoms to form halogenated hydrocarbons.
1 -Naphthalene anthracene, containing a fused cyclic aromatic hydrocarbon structure. Because of its conjugate system, it has certain chemical activity. It is easy to cause electrophilic substitution reaction, because the electron cloud density on the ring is high. In case of concentrated sulfuric acid and concentrated nitric acid mixed with acid, nitrification reaction can occur, and the nitro group enters the specific position of naphthalene anthracene ring; under the catalyst of halogen, it can also undergo halogenation reaction. And it has certain oxidation resistance. Because the conjugate system is stable, it can be oxidized to cause structural change under the action of strong oxidizing agent.
5 - Hidden acid, acid substance, has the general property of acid. It can react with active metals to generate hydrogen gas, such as with zinc particles, and hydrogen bubbles escape. It can neutralize with bases, such as with sodium hydroxide solution, to form salts and water. It can also react with metal oxides, like with copper oxide, which can dissolve black copper oxide and change the color of the solution.
Cobalt oxime, a complex containing cobalt. Its chemical properties are related to the coordination environment. Cobalt ions have various oxidation states and can undergo redox reactions under suitable conditions. Oxime groups can participate in coordination reactions to change the structure and properties of cobalt oxime. Cobalt oxime has potential in the field of catalysis and can catalyze specific organic reactions. Due to its special electronic structure and coordination ability, it can reduce the activation energy of the reaction and promote the reaction.

Build houses, erect beams and columns, and the wood can bear the weight, so that the house can be fixed, and it will not fall. And it is also good for the construction of weapons, and its benefits can be used for recruitment.
5-Acid, has the property of decay, but it is very useful to make good use of it. In the same way, it can be used to attract and help the power. It can also be used for metallurgy, to transform the stone, and to improve the gold.

Those who can gather and hide. It can be used for the essence of alchemy, and it can be used for the tripod, the essence of gathering, and it can be used for the pill. It can also be used for the water, which is not dense, and the water is kept clear.
All such things, whether for use or for work, are needed in the world. For work, to help the formation of tools and materials; for the harvest of crops; for the disease of the people. When used properly, it can eliminate advantages and disadvantages and benefit the people.

2-% heavy water-1-deuterium-5-boric acid + cobalt oxime should pay attention to the following things when storing:
First, the control of temperature and humidity. Although the properties of heavy water are relatively stable, high temperature or excessive humidity may affect its quality. Heavy water at high temperature may cause molecular movement to intensify, causing changes in physical properties; high humidity, or mixed with impurities, affecting purity. Boric acid is easy to absorb moisture. If the storage environment humidity is high, it is easy to deliquescent and agglomerate, changing its chemical activity. Cobalt oxime also has requirements for temperature and humidity. Improper temperature and humidity or structural changes will affect its chemical properties. Therefore, the storage place should be equipped with a temperature and humidity control device, the temperature should be maintained at 20 ° C - 25 ° C, and the humidity should be controlled at 40% - 60%.
Second, anti-oxidation and sealing. Cobalt oxime has certain reducing properties and is easily oxidized in the air, resulting in reduced performance. Therefore, when storing, it is necessary to ensure that the package is well sealed and can be filled with inert gases such as nitrogen to isolate the air and slow down the oxidation process. Although boric acid has relatively strong oxidation resistance, it may also react with gases such as carbon dioxide when exposed to the air for a long time, so it is also necessary to seal and store it. Although heavy water is not easy to oxidize, sealing can prevent impurities from mixing and maintain its purity.
Third, avoid light and isolation. Heavy water, boric acid and cobalt oxime are all sensitive to light. Light or luminescent chemical reactions change the structure and properties of the substance. For example, cobalt oxime is exposed to light, or excites intramolecular electron transitions, triggering uncontrollable reactions. Therefore, the storage place should be selected in a dark place or packaged with shading. At the same time, the three have different chemical properties. In order to prevent mutual reaction, they should be stored in isolation. Keep a certain distance between different substances and mark them clearly to prevent confusion and misuse.
Fourth, anti-vibration and stability. During storage, strong vibration should be avoided. The structure of cobalt oxime and other substances may be damaged due to vibration, which affects their performance. Especially for containers containing liquids such as heavy water, vibration or rupture of the container will cause danger. Therefore, storage facilities should be stable and keep a distance from possible vibration sources.

To make potassium dihydrogen, monosodium, pentaborax and zinc alum, the method is as follows:
To make potassium dihydrogen phosphate, the potassium hydroxide solution can be slowly dripped into the phosphoric acid solution, and the amount of the two can be controlled by the principle of acid-base neutralization, so that it can just form potassium dihydrogen phosphate. During the reaction, it needs to be monitored with an acid-base indicator or a pH meter until the solution reaches a suitable pH, and then evaporated, concentrated, cooled and crystallized to obtain potassium dihydrogen phosphate crystals, and then filtered, washed, and dried to obtain a pure product.
To make sodium chloride, the common method is seawater drying salt. Seawater is introduced into the salt field, and the water is evaporated by sunlight and wind, and the salt is gradually concentrated. After reaching a saturated state, sodium chloride crystallizes. It can also be obtained by chemical methods by neutralizing sodium hydroxide and hydrochloric acid. The reaction is rapid, and sodium chloride and water are formed. After evaporating the solution to remove the water, sodium chloride solids are obtained.
to prepare borax pentahydrate, which can be extracted from boron-magnesium ore. First, the boron-magnesium ore powder is co-heated with the soda ash solution to react to form borax and other substances, and then the insoluble impurities are removed by filtration. The filtrate is concentrated and cooled, and the borax pentahydrate crystallizes. After recrystallization, its purity can be improved.
to produce zinc sulfate, first, the reaction of zinc and dilute sulfuric acid, zinc as an active metal, and dilute sulfuric acid replacement reaction occurs, generating hydrogen and zinc sulfate solution, the reaction is completed, the unreacted zinc is filtered off, the solution is evaporated, concentrated, cooled and crystallized to obtain zinc sulfate crystals. Second, the reaction of zinc oxide and dilute sulfuric acid can also obtain zinc sulfate solution. The subsequent operation is similar to the former, and the product is prepared by evaporation, crystallization and other steps.
All kinds of production methods need to be carefully selected and carefully operated according to factors such as the availability of raw materials, cost and product purity requirements.

Today, there are 20% heavy silver, 10% purple copper, and 50% tin sand, plus lead and mercury. What is the price of the market? Let's talk about it as far as I know.
Heavy silver is precious in quality and is quite rare in the city. The price of every two cents is often in the spectrum of dozens of gold. If it is 20% heavy silver, its price should fluctuate with the price of silver according to its fineness, purity and current market conditions. And the price of silver often changes with the times, supply and demand. However, roughly speaking, if the color of each heavy silver is sufficient, it is worth between 20 gold and 30 gold, and 20% is about 40 gold to 60 gold.
Copper is also one of the hardware, its toughness and wide use. However, compared to silver, the price is slightly lower. The price of every two taels, or about the price of hardware. Ten percent of copper is about the value of hardware.
Tin sand has many uses and is often used in casters and other things. Fifty percent of tin sand, its price depends on its purity and quality. Ordinary tin sand is worth about three gold to hardware per composition, and about fifteen to twenty-five gold per 50%.
As for lead and lead, the quality is heavy and the price is average, and the mercury is strange and the price is special. The price of lead is about one gold per two taels, and mercury is expensive, every two or more is worth ten gold. However, I don't know how much lead and mercury each account for, and it is difficult to determine its value.
Overall, if you take a rough number, 20% of the heavy silver is worth 50 gold, 10% of the copper is worth hardware, and 50% of the tin sand is worth 20 gold. If lead and mercury are worth 10 gold, the total price of these things is about 85 gold. However, there is no constant price in the market, and it varies according to time, place, and quality. This is only an idea. The actual price must be carefully inspected by the market situation, and it can only be determined by asking the expert.
