Lead and mercury are common substances, each with unique physical properties.
Lead has a soft texture, is a silver-gray metal, and has good ductility. Its density is quite high, about 11.34 grams per cubic centimeter. This property allows lead to be used in many fields, such as manufacturing shot balls, with its high density to achieve specific motion effects. The melting point of lead is relatively low, 327.5 ° C. It is easy to melt into a liquid state under heating conditions. This property makes it widely used in the casting field and can be cast into various lead products. Although the conductivity of lead is not as good as that of copper, aluminum and other metals, it still has a certain conductivity. It is also used in some occasions where conductivity requirements are not high and other special properties are required. In addition, lead has good corrosion resistance and can resist the attack of many chemicals. It is often used in the manufacture of chemical equipment liners, battery shells, etc., to protect equipment from corrosion.
Mercury is commonly known as mercury. It is liquid at room temperature and pressure, which is its remarkable physical property. Mercury has high surface tension, rolls in a spherical shape, and shines like silver beads. Its density is also high, about 13.59 grams/cubic centimeter, which is higher than that of lead. Mercury has an extremely low melting point of -38.87 ° C and a boiling point of 356.6 ° C. This wide range of liquid characteristics makes it important for applications in thermometers, sphygmomanometers and other instruments, and can accurately indicate values with temperature changes. Mercury has good electrical conductivity and is used in some electronic components such as electrical switches and rectifiers. However, mercury is volatile and will slowly evaporate into mercury vapor at room temperature. Mercury vapor is toxic and requires extreme caution when used and handled.

Guanfu River and choline, the chemical properties of the two are related to the change of things and the reason of things, and have been studied by the world. Let's discuss it today to clarify whether its nature is stable or not.
The river, the convergence of water, Haohao soup. Its main component is water, and its chemical properties are relatively stable. Water is formed by the combination of hydrogen and oxygen, and its molecular structure is H2O O. Under normal temperature and pressure, water is liquid and its properties are peaceful. If it does not encounter special conditions such as high temperature and strong electricity, it rarely initiates violent chemical changes. For example, in rivers, water often coexists with sand, gravel, soil, etc., which is only a physical mixture, and there are few chemical reactions that cause its essence to change drastically. This is because the chemical bonds of hydrogen and oxygen in water molecules are stable, and considerable energy is required from the outside world to break them.
As for choline, it is an organic compound containing nitrogen. Its structure has a quaternary ammonium base part, which gives choline a certain chemical activity. Choline is easily soluble in water, in aqueous solution, or in an ionic state due to ionization. Encounters with many chemical reagents, or can initiate reactions. In case of acid, the quaternary ammonium base part of choline may undergo ion exchange reaction with hydrogen ions in the acid; in case of some oxidants, because the valence of some atoms in the structure is variable, it may also be oxidized. Compared with water, choline has more active chemical properties and is slightly less stable.
To sum up, the chemical properties of water, the main component of the river, are quite stable, while choline is relatively active due to its special structure, and its stability is inferior to water. The difference in chemical properties between the two stems from the characteristics of their internal atomic composition and chemical bonds. This is the wonder of the chemical world and the key to exploring the nature and laws of matter.

To prepare 1-alkyne and 2-cyanopyridine, there are many ways to synthesize them.
One of them can be through nucleophilic substitution reaction. Select an appropriate halogenated hydrocarbon, if you want to obtain 1-alkyne, the halogenated hydrocarbon one-terminal alkynyl group, and the reagent containing the active group, in a suitable solvent, under the catalysis of a base, the halogenated atom is replaced to form a 1-alkyne compound. As for 2-cyanopyridine, halogenated pyridine can be selected, and cyanide reagents, such as potassium cyanide, can be used. With the assistance of a phase transfer catalyst, the halogenated atom is replaced by a cyano group, so 2-cyanopyridine is obtained. In this process, it is necessary to pay attention to the reaction temperature, the strength and dosage of alkali, because these factors have a great influence on the reaction rate and product purity.
Second, metal-organic reagents are used. When preparing 1-alkynes, alkynyl-based reagents can react with suitable halogenated compounds. First, alkynyl-based reagents, such as alkynyl lithium or alkynyl magnesium reagents, are prepared, and then nucleophilic substitution occurs with halogenated hydrocarbons to generate 1-alkynes. Synthesis of 2-cyanopyridine, pyridine-based metal reagents can be used to react with cyanylating reagents. In this method, the preparation conditions of metal reagents are strict, the requirements for anhydrous and oxygen-free environments are high, and the
Third, through addition reaction. For 1-alkynes, unsaturated hydrocarbons can be obtained by addition of alkynyl-containing reagents. For example, alkenes and acetylene are added under the action of specific catalysts to form 1-alkynes. Synthesis of 2-cyanopyridine can be made by taking advantage of the unsaturation of the pyridine ring and the cyanide-containing reagents under the guidance of catalysts. The key to this approach lies in the choice of catalyst, and different catalysts have a significant impact on the selectivity and activity of the reaction.
In addition, the target molecule can be gradually constructed from common raw materials through multi-step reactions. For example, starting from simple hydrocarbons, through halogenation, substitution, addition and other series of reactions, 1-alkyne is obtained; pyridine derivatives are used as starting materials, and 2-cyanopyridine is synthesized through functional group conversion and cyano group introduction. Although this method has complicated steps, it can flexibly select raw materials and optimize the reaction route according to actual needs.

Mercury and cyanomercury are safe for storage and storage. Please pay attention to the following things:
The first priority is safety. Mercury is a toxic and heavy metal, and it is toxic. Its evaporation and inhalation can cause serious damage to the mind, digestion and immunity. Cyanomercury is also toxic, and it is a huge hazard to the human environment. Therefore, when operating both, you must follow safety procedures and wear protective clothing, gloves, gas masks, etc., to prevent skin contact and inhalation.
Furthermore, store it properly. Mercury should be kept in a sealed container to prevent damage. A small amount of water can be added to cover it to form a water seal. Cyanomercury should be stored in dry, dry, and well-connected places, and can be used to prevent fire, gas and oxidation. Due to its activity, in case of specific substances or pieces, it is easy to react biochemically and cause dangerous accidents.
In terms of production, according to the phase method, the combined method should be used. Mercury and cyanomercury are all dangerous chemical products, and it is necessary to have a suitable location to support them. The container should be firmly sealed to ensure that it is clear that it is dangerous, and that the contents and dangerous characteristics are clear. On the way, control the degree and temperature of the parts to avoid shocks and collisions, and avoid leakage caused by container breakage.
Once there is a leakage, it is urgent to report immediately. Evacuate the crowd around the area and set a warning. Manage the situation to prevent the leakage of mercury, and sprinkle sulfur powder to generate mercury sulfide, reduce toxicity, and then collect it carefully. Cyanomercury leakage, according to its chemical characteristics, chemical treatment, treatment of waste residue, according to the dangerous waste disposal.
