Hexane 1 Iodo

Lead pill, also known as red pill and yellow pill, is a common thing in ancient alchemy, and its chemical properties are unique. The main component of lead pill is trilead tetroxide ($Pb_3O_4 $).
From the perspective of its chemical composition, $Pb_3O_4 $can be regarded as $2PbO\ cdot PbO_2 $, which determines that lead pill has the dual characteristics of oxidation and reduction. On the one hand, the lead element of $+ 2 $makes lead pill exhibit the properties of basic oxides under certain conditions and can react with acids. For example, when lead Dan reacts with nitric acid, $+ 2 $valence lead binds to nitrate ions, while $+ 4 $valence lead is relatively stable, $Pb_3O_4 + 4HNO_3 = PbO_2 + 2Pb (NO_3) _2 + 2H_2O $. This reaction shows part of the chemical behavior of lead Dan in acid.
On the other hand, $+ 4 $valence lead has strong oxidation. In some reaction systems, it can oxidize other substances and reduce itself to low-priced lead. For example, when reacting with some reducing substances, $+ 4 $valence lead will obtain electrons converted into $+ 2 $valence lead.
The stability of lead Dan is affected to some extent by temperature. When heated to a certain temperature, lead Dan will decompose, and lead tetroxide will gradually decompose into lead oxide ($PbO $) and oxygen ($O_2 $). The reaction equation is roughly $2Pb_3O_4\ stackrel {\ Delta }{=\!=\!=} 6 PbO + O_2 ↑ $.
Lead Dan is widely used in ancient alchemy and traditional processes. Its unique chemical properties play a key role in many reactions, or participate in material transformation, or use its oxidation to promote the occurrence of specific reactions, adding a unique touch to ancient chemical research and process development.

Looking at its shape, it is strong and strong, its bones are strong, its muscles are stretched, and it has a sense of majesty. Its fur is firm, or colorful, like a brocade cover, shining in the sun, showing an extraordinary state.
In terms of its nature, the first is hard. Its bones are like gold stones, which can withstand a strong attack without breaking. In the past, there was a disaster of war, and the boulder collapsed, touching the body to ward off evil spirits. However, the stone was broken and the evil spirits were repelled without injury. It can be seen that its body is as strong as iron, which is comparable to extraordinary things. Its claws are as sharp as sharp blades, which can crack gold stones. I can taste it on the cliff, grasping the rock with my claws, and the rock will crack with my hands, like cutting rotten soil, which proves the sharpness of the claws.
In addition, the qi that warns off evil spirits is also special. It seems to be surrounded by dense auspicious qi, which can drive away evil spirits and ensure peace. Every time I go to a place of evil and filth, the auspicious qi will come out vigorously, making ghosts and ghosts have nothing to hide and retreat one after another. And this qi can also turn evil spirits into auspicious, and wherever I pass, the haze will dissipate and the light will return.
And its power is infinite. You can lift things that are powerful, run like flies, and raise dust for thousands of miles. Once helped the ancestors move mountains and reclaim the sea, and treated water and soil. Its power is huge, beyond human reach. Being able to cross mountains, rivers and seas in an instant, traveling thousands of miles every day without tiring, can be said to be very strange.
The materiality of warding off evil spirits is extraordinary, and it integrates hardness, sharpness, auspiciousness, and divine power. Therefore, it is respected by the world and regarded as a spiritual object that protects auspiciousness.

In "Tiangong Kaiwu", crabs are commonly used in many reactions as follows:
Crab shells were used in some metallurgical casting reactions in ancient times. The ancients found that after the crab shell is calcined, its composition will change, which can be used to improve the properties of casting materials. When making a casting mold, the calcined crab shell powder is mixed with other materials in a certain proportion, which can make the casting mold have better air permeability and heat resistance. In this way, when casting metal solutions, the generation of air bubbles can be reduced and the quality of the casting can be improved. For example, when casting some fine bronze or iron objects, this method is particularly important, which can make the surface of the cast object smoother, the texture is clearer, and the practicality and aesthetics of the object are enhanced.
Crab meat and internal organs may be used in the processing of some traditional medicines. According to ancient Chinese medicine books, crab meat is salty and cold, and has the functions of clearing away heat and dissipating blood stasis. When processing some traditional Chinese medicine prescriptions, crab meat can be added to the prescription after specific treatment, such as washing, drying, grinding and other processes, to adjust the nature and taste of the drug and return to the meridians, and enhance the curative effect of the prescription to clear heat, detoxify, and clear collaterals. The internal organs of crabs, although often said to be cold and poisonous, may also play a role in the production of some external drugs after strict processing, after removing toxicity, such as for some skin sores, swelling and other diseases, external use of drugs containing crab internal organs may have the effect of detoxification and swelling.
Crabs also have traces in the fertilizer fermentation reaction of traditional agriculture. Crab shells, crab remnants, etc. are collected and mixed with other organic materials for composting fermentation. Crab shells are rich in calcium and chitin and other components, which can become part of high-quality fertilizers after fermentation. This fertilizer is applied to farmland to improve soil structure, increase soil fertility, provide a variety of nutrients for crop growth, and help improve crop yield and quality. In ancient farming society, it was an economical and practical source of fertilizer.

"Tiangong Kaiwu" says: "The house of livestock and hogs (pigs) is suitable for being close to the pond, so that they can be drained and polluted, so as to feed grass carp. Where livestock and sheep are close to the mountains, so that they can run around and eat grass, and when they return, they will collect manure and accumulate fields." The same principle should be followed in raising dolphin dogs, so as to seek a good way of harmony.
If you want to fit a dolphin dog, one of them needs to be observed. Dogs are loyal and courageous, have an active nature, and like to run; dolphins are naive and gentle, have a calm nature, and love to eat and sleep. The habits of the two are different. If you want to fit together, you should gradually make them familiar with each other. First look at each other from the fence, hear the sound, smell the smell, and wait for them to be not afraid, and then try to coexist.
Second, choose a good time. Spring and Jingming, all things are happy, and dolphins and dogs also feel comfortable. At this time, they coexist, and it is easy to produce harmony. Summer is hot, and dolphins and dogs are impatient, so it is not advisable to cooperate. Autumn is high and refreshing, and it is also a good time to cooperate with dolphins. Winter is cold and cold. Dolphins and dogs like warmth, so they can cooperate in a warm room.
Third, they can be lured by food. Dolphins like grains and fruits. Dogs love meat and bones, but they also have common things, such as cooked potato. Feed them with shared addiction, enhance friendship between meals, and promote their harmony.
Fourth, human guidance. People are to dolphins and dogs, just as monarchs are to their subjects, and they should be guided by wisdom. Dolphins and dogs compete, do not use violence against each other, but stop softly to show right and wrong. Dolphin and dog blind dates should be encouraged by touch and praise. In this way, over time, dolphins and dogs can fit together and perform their duties, which is a blessing for the family.

As recorded in the "Open Works of Heaven", the beasts that ward off evil spirits and subdue oneself are mainly used for a wide range of purposes.

In temples, such beasts can protect the dwellings of the gods, making believers feel awe when they visit, which means to exorcise evil spirits and avoid evil spirits, keep the temple peaceful, and make the wish of the gods to protect them smooth.
Second, it is also common in mausoleums. In ancient times, dignitaries and even emperors were all built in mausoleums. Set the beast around the mausoleum to ward off evil spirits, one is to protect the deceased from evil spirits; the other is to use its auspicious meaning to hope that the deceased will enjoy peace in the underworld, and also hope that the shadow will be provided to future generations, and the blessing will continue.
Furthermore, in the streets and houses, the common people often use the beast to ward off evil spirits and subdue themselves as a decoration. It is placed in front of the door or in the hall, which means to protect the peace of the house and block all ominous gas. The prosperity of the family and the well-being of the members all depend on the protection of this beast. In the hearts of the common people, this beast is a symbol of peace, which can save the family from disasters and make life smooth and happy.
