5-Methoxybenzofuran-2-carboxylic acid, this substance is occasionally involved in the chemical and pharmaceutical fields. However, I don't have the details, so I dare not say anything.
And calcium phosphate, its physical properties are as follows:
Calcium phosphate is a white solid with a fine texture like powder, odorless and odorless. Its density is quite high, about 3.14 grams/cubic centimeter, which makes it have a certain sense of weight. Stable under normal conditions, it is not easy to react with common substances around.
Its melting point is very high, about 1670 ° C. To melt it into a liquid state, an extremely high temperature environment is required. In water, calcium phosphate has very little solubility, making it difficult to dissolve in water. Therefore, it mostly exists in the form of precipitation in water, and it sinks to the bottom after standing.
Calcium phosphate is quite stable to light. Under light, its chemical structure and physical form do not change significantly, and it is not easy to decompose or deteriorate due to light radiation.
In addition, calcium phosphate has a certain hardness. Although it is not as hard as gold and stone, it is enough to maintain its own morphological stability and is not easy to deform under the slight action of external forces. Its powder is delicate to the touch and has good particle uniformity. In industrial production and experimental operations, this property facilitates its uniform mixing with other substances, which is conducive to subsequent reactions.

Eh, the chemical properties of Fujiao sand are often doubted whether it is stable or not. The kao sand is the crystal of the halide mineral kao sand. Its main component is ammonium chloride.
Ammonium chloride is more active and stable at room temperature. However, when it is hot, it is easy to decompose and sublimate into a gas. This is also the characteristic of being different from others.
If the kao sand is placed in a high temperature environment, ammonium chloride will be divided into ammonia and hydrogen chloride gas. Both are gaseous and float in the air. And the kao sand is easily soluble in water, and in water it dissociates into ammonium ions and chloride ions.
Ammonium ions can react with alkali substances to form ammonia gas and water, which is another significant chemical change. Therefore, although the turmeric sand seems to be stable at room temperature, when it encounters specific conditions, such as high temperature and alkali, its chemical properties are active, unlike that of gold stone.
As for 5-aminoacetamide thiazole-2-carboxylic acid, this is also a chemical substance. However, it is very different from turmeric sand. This organic compound has a complex structure and contains nitrogen, oxygen, sulfur and other elements. Its chemical properties are determined by its structure and have specific reactivity and stability. However, if you want to describe it in detail, it cannot be expressed in a single word, and it also depends on the specific reaction conditions and environment. In short, the properties of chemical substances vary with the environment, and the sand and 5-aminoacetamidothiazole-2-carboxylic acid cannot be excluded from this principle.

The synthesis of 5-methoxybenzofuran-2-carboxylic acid involves many ingenious methods, all of which have been developed by skilled craftsmen over a long period of time.
First, the corresponding phenolic compound can be started. First, the phenol and the halogenated hydrocarbon are reacted in the presence of an appropriate base to form a methoxylated product. This reaction requires precise control of the reaction conditions, such as temperature, amount of base, and ratio of reactants. If the temperature is too high or too low, the reaction may be biased towards side reactions, resulting in a decrease in yield. Improper amount of base may also affect the reaction process. Then, through a specific cyclization reaction, the furan ring structure is formed in the molecule. In this step, the choice of catalyst is crucial, and different catalysts have a great influence on the reaction rate and selectivity. After a series of reactions, the basic structure of 5-methoxybenzofuran-2-carboxylic acid is gradually constructed.
Second, the aldehyde compound containing the benzene ring is used as the raw material. First, the condensation reaction occurs with the furan fragment reagent with a specific structure. This condensation reaction needs to be carried out in a suitable solvent and catalytic system. The polarity and solubility of the solvent will affect the dispersion and reactivity of the reactants. The optimization of the catalytic system, such as the selection of acidic or basic catalysts, and the precise regulation of their dosage, is related to whether the reaction can proceed smoothly. After condensation, the carboxyl group is introduced through oxidation or other functional group conversion reactions to obtain the target product 5-methoxybenzofuran-2-carboxylic acid.
Third, there are also methods using natural products as starting materials. Some natural products have a partial structural skeleton similar to the target product. By chemically modifying the natural product, it is gradually converted into 5-methoxybenzofuran-2-carboxylic acid. This approach requires in-depth understanding of the source and extraction method of the natural product, and careful selection of reaction reagents and conditions during the modification process to avoid excessive damage to the original structure, while ensuring that the required methoxy, furan ring and carboxyl groups can be effectively introduced.
Each of these synthesis methods has its own advantages and disadvantages. It is necessary to carefully choose the appropriate synthesis path according to actual needs, such as the availability of raw materials, cost considerations, and the purity requirements of the target product, in order to achieve the ideal synthesis effect.

In the commercial market of the world, the price of rock salt varies, and it is difficult to generalize.
I have heard that rock salt produced in various places has different qualities, and its price is also different. In the market, the price of crude rock salt may be slightly cheaper. Such rock salt, or impurities, are slightly more, and the processing art is not perfect, but it can be used for seasoning in ordinary people's homes. Its price is between a few and more than ten texts per catty.
If the refined rock salt is well-selected and finely processed, its impurities are removed, its purity is improved, and beneficial elements may be added, which may be beneficial to the way of health. This kind of rock salt is mostly used by rich families and those who pay attention to taste, but its price is higher. It can reach dozens of texts per catty, or even nearly a hundred.
In addition, the supply and demand of the city is also related to the price of rock salt. If rock salt is abundant at a certain time, and the supply in the city exceeds the demand, the price will drop; on the contrary, if the production is insufficient and there are many seekers, the price will rise. Moreover, the origin of salt is far and near, and the difficulty of transportation also affects its price. Salt from distant places must be added to the price of salt after long-distance transshipment.
Furthermore, the commerce of the world is divided into official and private sectors. Salt from the official sector is made and sold in an orderly manner, and the price may be stable; salt from the private sector, in the midst of competition, the price may vary. Therefore, if you want to know the exact price of rock salt, you can get the details when you observe the situation of the time and place and the state of the market.
