What is the use of N, N -dicyclohexylbenzothiazole-2 -sulfinamide

"Tiangong Kaiwu" says: "All ramie has no soil and no growth. It is planted in two ways: sprinkling seeds and splitting heads, and the colors are green and yellow." And the sub-tip bluegrass is quite widely used.

The sub-tip bluegrass can be used for dyeing. Its leaves contain cyanosides, which can be hydrolyzed and fermented to produce indigo, an important blue dye in ancient times. The ancients dyed it with sub-tip bluegrass, and the dyed fabrics were bright and lasting. The Book of Songs says: "The blue will be collected in the end of the dynasty, and it will not produce one." The "blue" here may include the sub-tip bluegrass, which shows that it was picked and used for dyeing at that time.

The sub-tip bluegrass also has medicinal value. According to many ancient medical books, its cold nature has the effect of clearing away heat and detoxifying, cooling blood and stopping bleeding. It can be used to treat symptoms such as heat poisoning, bleeding and so on. In the folk, there are also prescriptions for treating diseases with bluegrass as medicine. Although there is no modern precision medicine demonstration, it played an important role in the treatment of diseases for the people in the environment of lack of medicine in ancient times.

In addition, bluegrass has also contributed to agriculture. Its growth characteristics make it suitable for use as green fertilizer. By plowing it into the soil and decomposing it, it can increase soil fertility, improve soil structure, and facilitate the growth of other crops. This is the embodiment of the simple but practical agricultural production wisdom of the ancients. In conclusion, bluegrass has shown unique uses in dyeing, medicinal, agricultural and other fields, contributing a lot to the development of ancient society.

What are the physicochemical properties of N, N -dicyclohexylbenzothiazole-2 -sulfinamide

Eh! The rationalization of sulfuric acid is the gist of the rationalization, and it is useful in the field of work and life. Today.

Sulfuric acid is a compound formed by the dissolution of sulfur dioxide in water, and its chemical formula is\ (H_ {2} SO_ {3}\).

In terms of chemical properties, sulfuric acid solutions are often colored liquid, with the unique irritation of sulfur dioxide.

In terms of chemical properties, sulfuric acid is acidic, because it can produce sulfuric acid. However, its acidity is low in sulfuric acid, and sulfuric acid and sulfuric acid are weak. In water, sulfuric acid is synthesized by step, and the sulfuric acid is synthesized into sulfuric acid (\ (HSO_ {3 }^{-}\)）， and part of the sulfuric acid is then synthesized into sulfuric acid (\ (SO_ {3} ^ {2 - }\)）。

sulfuric acid is original, which is one of its important properties. Because the combination of sulfur is low, it can be oxidized by polyoxides. For example, when encountering oxidized high-acid solutions, sulfuric acid can be reduced to its original, causing the violet color of the high-acid solution to fade. And sulfuric acid can be slowly oxidized by oxygen in the air, which is also uncertain.

In addition, sulfuric acid also has a certain oxidizability. Its oxidizability is weak, and when it encounters the original sulfuric acid, it can also show its oxidizability. If the sulfurization meets, the original reaction of oxidation can be generated, and the sulfur is generated, that is, there is no color precipitation.

Furthermore, the uncertainty of sulfuric acid cannot be ignored. Sulfuric acid is easy to decompose with sulfur dioxide in water, which means that sulfur dioxide dissolves in water to form the reverse reaction of sulfuric acid. Add or place, the decomposition of sulfuric acid is faster, so the sulfuric acid solution should be prepared with sulfuric acid to ensure its stability.

What are the precautions in the production process of N, N -dicyclohexylbenzothiazole-2 -sulfinamide

"Tiangong Kaiwu" says: It is like nutmeg, gluten, mustard, all of which are fresh and fragrant. As for Ferwei, it is extremely stinky. However, it is used in medicine, and its bizarre nature is also due to its own reasons. In the production process of Ferwei, there are many points to pay attention to, which should be carefully observed.

First, the harvest season must be clearly distinguished. Ferwei was born in Xifan and Kunlun, etc., and its ointment is suitable for harvesting in late spring and early summer. At this time, Ferwei plants are flourishing and contain sufficient active ingredients, and the quality of the ointment harvested is high. If harvesting is too early, the ointment is not abundant and the ingredients are insufficient; if it is too late, the climate will be hot, and the ointment will easily evaporate and dissipate, which will damage its quality.

Second, the method of collection should be appropriate. When picking, cut the stem with a sharp blade, so that the lipid paste flows out, and take it with utensils. However, be careful not to hurt the root shaft, so as not to affect the vitality of the plant and cause it to be difficult to reproduce in the coming year. And the receiving utensils must be clean, do not let dirt and debris mix in and stain the lipid paste.

Third, the processing work needs to be fine. After picking the ferulic lipid paste, either dry it in the sun or bake it, according to its use and medicinal properties. When processing, the key is to grasp the heat. If the fire is large, the lipid paste will be burnt and its medicinal properties will be lost; if the fire is small, it will be insufficient drying and easy to cause mildew. Or in combination with other medicines, it must be prepared in accordance with the ancient regulations and with accurate proportions, so that Feruvius can be used effectively.

Fourth, the method of storage is also important. Feruvius is volatile and has a specific smell, so it must be stored in a sealed and cool place. The containers used should preferably be porcelain bottles and clay jars, which can prevent its odor from dissipating, and can also avoid moisture and insect moths. In this way, the medicinal effect of Feruvius can be preserved for a long time for medicinal use.

What is the synthesis method of N, N -dicyclohexylbenzothiazole-2 -sulfinamide

To prepare the asaxine capsule, the method is as follows:
Take an appropriate amount of divinylbenzene first, which is the basis for building the structure. Divinylbenzene has unique chemical properties and can form a stable structural framework during the reaction. Place it in a clean reaction vessel and prepare for the next step of the reaction.
Then, carefully select the appropriate initiator. The initiator is like the "igniter" of the reaction, which can promote the smooth initiation of the reaction. According to the reaction conditions and expected effect, carefully select the appropriate initiator and slowly add it to the container containing divinylbenzene in quantity. When adding, pay close attention to the changes in the reaction system to prevent the reaction from going out of control due to excessive addition.
Subsequently, adjust the temperature and pressure of the reaction. Appropriate temperature and pressure are the keys to a successful reaction. Through precise temperature control and pressure regulation equipment, the reaction environment is maintained within a specific range. If the temperature is too high, the reaction may be too violent, resulting in impure products; if the temperature is too low, the reaction will be slow or even stagnant. The same is true for pressure, which needs to be just right to make the collision and bonding between molecules more effective.
During the reaction process, continue to stir the reaction mixture. Stirring can promote the complete mixing of the ingredients to ensure that the reaction proceeds evenly. Magnetic stirring or mechanical stirring can be used, depending on the specifications and reaction characteristics of the reaction vessel. The stirring rate should also be appropriate. Too fast or too slow will affect the reaction effect.
When the reaction reaches the desired level, use appropriate separation and purification methods. The purpose of this step is to remove unreacted raw materials, by-products and impurities to obtain high-purity asaxine sacs. Filtration, distillation, extraction and other methods can be used to flexibly select according to the properties of the product and the characteristics of impurities. After careful separation and purification, the asaxine sacs that meet the requirements can be prepared.
