3-Chlorobenzo[b]thiophene-2-carboxylic acid

Borax is a common inorganic substance with unique physical properties. The form of borax, at room temperature, is mostly colorless translucent crystals or white crystalline powder, which is delicate and delicate, just like the purity of the first snow in winter. Its touch is delicate and smooth, and it touches the fingertips lightly, just like a wisp of wind sliding by.
The density of borax is about 1.73g/cm ³. Compared with many common substances, this value has unique characteristics. When placed in the hand, it can feel its weight is moderate, neither too heavy nor too light. And the hardness of borax is low. With a light swipe of the fingernail, fine marks can be seen, just like a gentle stroke leaving a mark on rice paper.
Furthermore, borax also has significant performance in terms of solubility. Borax is soluble in water. When borax is slowly integrated into the water, it seems to quietly hide its body and turn into an invisible existence. However, the dissolution process is not completed instantaneously, but gradually integrates over time, just like ice and snow gradually melt under the warm sun. And the solubility of borax varies with temperature changes. When the temperature increases, the solubility also increases. This is its unique physical property.
In addition, borax has a certain degree of moisture absorption. In a humid environment, borax is like a guardian who silently absorbs moisture, which will absorb water vapor in the air, causing it to gradually become moist and may even partially dissolve. This moisture absorption needs to be considered in many practical applications.
The melting point of borax is about 741 ° C. When the temperature rises to this point, borax will gradually transform from solid to liquid, like a sleeping butterfly, under the catalysis of high temperature, breaking the cocoon into a butterfly, realizing the transformation of form. Its boiling point is as high as 1575 ° C. At this temperature, borax will completely transform into gaseous state and start a different "journey".
The physical properties of borax are rich and diverse, from morphology, density, hardness, solubility, hygroscopicity, to melting point and boiling point, all show its unique charm, and play an indispensable role in many fields due to its unique physical properties.

Borax is also a compound of boron. Its chemical properties are unique and have several characteristics.
First word solubility, borax is easily soluble in water, and in hot water, its dissolution is smoother. It can be dissociated in water to form borate ions and metal ions. This property makes it able to participate in the process of ion exchange in many chemical reactions.
Times and acidity, the aqueous solution of borax is weakly alkaline. Because borate ions can combine with hydrogen ions in water, the concentration of hydroxide ions is relatively high, so it appears alkaline. This weakly alkaline property can be used as a buffer to stabilize the pH of the solution and ensure the smooth progress of the reaction in some chemical reactions or industrial processes that require pH regulation. < Br >
Furthermore, borax has certain oxidizing properties. Although its oxidizing properties are weaker than common strong oxidants, under certain conditions, it can cause some substances to oxidize. In some metallurgical processes, borax can assist in removing impurities in metals, and its oxidizing properties can oxidize impurities into easily separated forms.
In addition, borax can complex with a variety of metal ions. It can form stable complexes with copper ions, iron ions, etc. This property is often used in analytical chemistry for qualitative and quantitative analysis of metal ions.
Borax can react with acid to form boric acid. Boric acid is a weak acid, and this reaction is reversible. With this reaction, borax can release boric acid in acidic environments, and boric acid is widely used in medicine, anti-corrosion and other fields.
The chemical properties of borax are rich and diverse, and it has important applications in chemical industry, metallurgy, medicine, analytical chemistry and many other fields. With its unique properties, it has made great contributions to the development of various industries.

"Heavenly Works", Butteric acid is the acid produced by the transformation of milk. The methods are many, and the list is as follows:
First, start with milk. The new milk is placed in the milk, so that it can be naturally leavened. Milk contains general microorganisms. Under suitable conditions, microorganisms multiply and promote the reduction of lactose into butyric acid. This is a method commonly used in ancient methods. The operation is easy, but it is necessary to pay attention to the degree of growth, whether it is easy to cause the growth of bacteria, and its milk.
Second, introduce the milk with sour milk. Take the yogurt that already contains butteracid and add it to the new milk. The beneficial microorganisms of yogurt can be used as a leavening primer to accelerate the production of butteracid. This method can make the fermentation process easier to control, can shorten the fermentation process, and because of the introduction of butyric acid bacteria, it is not easy to be dried by external butyric acid bacteria, so the butyric acid product is determined.
Third, cultivate with specific bacteria. If you want to get more accurate and stable butyric acid, you can use a specific butyric acid bacteria. This bacteria can be integrated into the sterilized milk according to a certain proportion, and carefully control the degree, degree and other parts, so that it can multiply butyric acid in large quantities. This method requires a lot of technical skills, but it can precisely control the generation of butyric acid, and is suitable for large-scale or high-quality products.
Therefore, the methods of butyric acid are short, easy to be natural, or fine and controllable, depending on factors such as the quality of the product and the quality of the product.

In "Tiangong Kaiwu", the use of butyric acid is quite extensive. In the field of food and cuisine, butyric acid can be used to make cheese. The method is based on cow and goat milk, and when it is fermented, butyric acid will grow. Butyric acid coagulates the milk and precipitates into cheese and whey. The cheese made has a unique flavor and is resistant to storage. It is a good product in food.
In the realm of medicine, butyric acid also has its functions. Ancient healers knew that butyric acid has mild antibacterial properties. External use can be applied to sores to help them converge and heal; internal use can adjust the stomach and slow down various diseases in the abdomen. Although medicine at that time was not as detailed as it is today, the effect of butyric acid was also valued by doctors.
Furthermore, in the brewing industry, butyric acid participates in the fermentation process. When making wine, moderate production of butyric acid can increase the mellow flavor of the wine. During the fermentation of fermented grains, various microorganisms coexist, and butyric acid interacts with alcohols and other substances to enrich the aroma and taste of the wine.
In the field of leather manufacturing, butyric acid also plays a role. When tanning leather, treating leather with something containing butyric acid can make the leather more flexible, anti-corrosive, and prolong the service life of the leather.
In short, butyric acid has its unique uses in the fields of diet, medicine, brewing, and leather. Although ancient knowledge may be limited, its contribution to people's livelihood should not be underestimated.
