Carbonic acid and guanidine (1:2) When using, there are several precautions to keep in mind.
First, it is related to safety protection. The mixture of the two may be corrosive and irritating to a certain extent. When operating, be sure to wear appropriate protective equipment, such as protective clothing, protective gloves and protective goggles, to prevent it from touching the skin and eyes and causing burns and other hazards. In case of accidental contact, rinse with plenty of water immediately, and decide whether to seek medical attention according to the severity of the injury.
Second, environmental conditions are very critical. This reaction may require ambient temperature and humidity. In general, it is necessary to operate in a dry and well-ventilated place to avoid excessive ambient humidity affecting the reaction process. At the same time, good ventilation can disperse the harmful gases that may be generated in time. In terms of temperature, it should be maintained within a specific range. Too high or too low may cause abnormal reaction rate and affect the quality of the product.
Third, accurately control the dosage ratio. The established ratio of carbonate to guanidine is 1:2, which is determined by repeated tests and studies. If the ratio is deviated, the reaction may not be fully carried out, or an unexpected product may be generated. Therefore, when weighing the two, it is necessary to use a precise measuring instrument to ensure that the ratio is accurate.
Fourth, the operation process also needs to be cautious. The order of addition may affect the reaction. Usually, carbonic acid and guanidine should be mixed in a specific order, and the addition process should be slow, and stirred at the same time to promote uniform mixing, so that the reaction occurs smoothly. If the addition is too rapid, or the reaction is too violent, causing danger.
Fifth, properly store the remaining substances. If there is an unused mixture of carbonic acid and guanidine (1:2), it should be sealed and stored in a cool and dry place. Due to its active chemical properties, exposure to air or contact with other substances, or deterioration, it will affect the subsequent use effect.

The compound formed by carbonic acid and guanidine (1:2) has unique physical and chemical properties. In appearance, this compound is often in a white crystalline state, with a pure texture and uniform particles. It looks quite regular.
When it comes to solubility, it exhibits good solubility in water. Because guanidine is alkaline, it can react with carbonic acid to form ionic compounds, so it is easily soluble in polar solvent water. When mixed into water, it is like ice crystals that melt in a stream when they meet warmth, and quickly disperse to form a uniform solution.
In terms of stability, this compound is quite stable at room temperature and pressure. However, in case of high temperature environment, its structure will change. Due to the fact that the carbonic acid part is easily decomposed by heat, or the structure of the overall compound is changed, just like a delicate instrument exposed to the hot sun for a long time, it gradually loses its original form.
Its acidity and alkalinity also have characteristics. Although it is combined with carbonic acid and guanidine, the aqueous solution of the compound is weakly alkaline due to the strong alkalinity of guanidine. Like a mild alkali solution, it can play a specific role in chemical reactions.
In terms of chemical reactivity, this compound is quite active. Some groups in its structure can react with a variety of reagents, such as further neutralizing with acids, and can also react with carbonyl compounds such as aldars and ketones under specific conditions. Just like a smart dancer, he dances with different dance partners on the chemical stage to derive a variety of products.

To make carbonic acid-guanidine (1:2), the method is as follows:
First prepare the required materials, both carbonic acid and guanidine are necessary, and clean utensils are required, such as glass beakers, gauges, etc.
First take an appropriate amount of water and pour it into the beaker. The amount of water depends on the amount of the product to be prepared. It is usually appropriate to fully dissolve the material.
Pour the guanidine slowly into the water, and keep stirring during this time to make the guanidine gradually dissolve. This step needs to be slow and even to prevent it from being insoluble in agglomeration.
When the guanidine is dissolved, slowly add carbonic acid and keep stirring to make the two fully blend and react. During this process, it can be seen that the solution has slight changes, or there are bubbles, or the color is slightly changed, which is normal.
Keep stirring until the reaction reaches an equilibrium state. At this time, the composition of the solution is close to carbonate-guanidine (1:2).
If you want to get a pure thing, you need to follow up. Filtration can be used to remove insoluble impurities. If the solution has excess water, you can use the technique of evaporation and low temperature. In addition to its water, the temperature should not be too high, which may damage the properties of the product.
In this way, after various steps, you can get carbonate-guanidine (1:2). When preparing, you need to follow the procedures, pay attention to safety, prevent the material from splashing out and hurting people, and prevent the escape of harmful gases.

The compound of carbon (acid) and guanidine (1:2) often involves a variety of reactions. In the context of "Tiangong Kaiwu", it is analogous to the reaction of various things in the world.
First, when encountering alkalis, such as alkali metal hydroxides, it is like water and fire meeting, causing a neutralization. Guanidine carbonate has acidic characteristics, and alkali is alkaline. The two are in contact. Carbonate is combined with metal ions, and guanidine cations are also neutralized with hydroxide, turning into salt and water, just like the state of yin and yang.
Second, when heated, it is like a phoenix nirvana, and guanidine carbonate decomposes. Carbonic acid is partially transformed into carbon dioxide and water, which escapes in the air, while guanidine may remain, or further decompose, depending on the temperature and environment, just like the metamorphosis of the old and the new form.
Third, it encounters with metal salts, just like princes fighting for land, and starts to decompose again and again. The exchange of the carbonate radical of guanidine carbonate and the cation of the metal salt gives birth to new carbonates and guanidine salts. Looking at the reaction, it can be seen that the transformation of matter is wonderful, just like the change of power in the world, and each has its own return.
Fourth, in an oxidizing environment, guanidine carbonate can be oxidized. The guanidine group or carbonate part is attacked by oxidants, the structure is broken, and oxidation products are formed, or it contains nitrogen oxides, carboxylic acids, etc., just like the change of warriors on the battlefield, the old appearance is changed.
These various reactions follow the rules of heaven and earth chemistry. In the microscopic domain, matter interacts and evolves thousands of changes, just like the principle of creation of all things described in "Tiangong Kaiwu", showing the magic of natural chemistry from micro to micro.
