1. **: This compound may contain groups that can be oxidized, so it has. Such as aldehyde groups, groups and other groups can lose in the appropriate parts, so that other things are, itself oxidizing reaction.
2. ** acid *: If its molecule contains acidic groups such as carboxyl groups, can be acidic, can be neutralized and reversed; if it contains groups such as amino groups, can be, can be acid.
3. ** Substitution: Some atoms or groups in its molecules can be replaced by other atoms or groups in the appropriate parts. For example, if it contains a atom, can be replaced by other nuclei and replaced by other nuclei.
4. ** Addition inverse *: If there are no and in the molecule, such as carbon, carbon three, etc., can generate addition inverse. For example,, element and other additions, so that and of and and.
5. ** Hydrolysis inverse *: If there are ester groups, amido groups and other groups in the molecule, it can be hydrolyzed under the catalysis of acids or. The hydrolysis of the ester group produces a phase of acids and alcohols, and the hydrolysis of the amido group produces a phase of acids and amines.
What is the synthesis method of 2- (5-bromoquinoxaline-6-yl) guanidine?
To make di- (five-glazed-six-base) ether, the method is as follows:
Prepare glazed first, and the glazed one is an amorphous solid obtained by melting and cooling quartz sand, soda ash, feldspar and limestone at high temperature. Choose the pure color one, break it into small pieces, place it in a crucible, burn it with charcoal fire, and melt it into a liquid.
As for the six-base, it is necessary to use a specific medicinal material and mix it in a certain ratio. Take a clean container, put the medicines in sequence, and grind it with a pestle and mortar to make it uniform. Then slowly fry over low heat, stirring continuously until it forms a thick paste to obtain the six-base raw materials.
When the glazed melt and the six-base raw materials are ready, slowly pour the six-base raw materials into the glazed melt, and quickly stir with special bamboo chopsticks to fully integrate the two. When stirring, pay attention to the heat, not too large, so as not to burn the raw materials; nor too small, resulting in poor fusion.
After fusion, pour the mixture out of the crucible, place it on a flat stone plate, and spread it out with a shovel to cool naturally. After cooling, the solid state of di- (five-glazed-six-yl) ether can be obtained. Then with a file and other tools, it is trimmed to the desired shape and size, which is the finished product. The whole process needs to be handled carefully, paying attention to the heat, proportion and degree of fusion, to obtain a good product.
What are the safety risks of 2- (5-bromoquinoxaline-6-yl) guanidine?
2-%285-%E6%BA%B4%E5%96%B9%E5%96%94%E5%95%89-6-%E5%9F%BA%29%E8%83%8D%E5%AD%98%E5%9C%A8%E5%A4%9A%E5%A4%9A%E6%9C%89%E5%90%84%E7%A7%8D%E5%AE%89%E5%85%A8%E9%A3%8E%E9%99%A9, I will analyze it in detail today.
This agent is hidden in all kinds of dangerous places, and the first one is the risk of temperature and humidity. If it is hidden in a high temperature place, its 2- (5-boric acid-6-based) naphthalene is stored, and the internal structure may be easily changed due to heat, the medicinal force will be impaired, and the medicinal effect will be difficult to complete. And where the humidity is too high, the water vapor will easily invade, or cause it to deliquescent, becoming a useless ointment.
Furthermore, light is also a serious problem. Exposed to strong light, the components in the 2- (5-boric acid-6-based) naphthalene reservoir may change qualitatively due to photochemical reactions, losing their original properties, just like beautiful jade dusted and no longer shining in the past.
The disturbance of microorganisms cannot be ignored. If the environment is unclean, microorganisms will multiply, attach to the 2- (5-boric acid-6-based) naphthalene reservoir, or react with it, damaging its quality, such as silverfish insects eating wood, gradually destroying the foundation.
In addition, there is also a risk of vibration and collision. Violent vibration, or cause damage to its packaging, 2 - (5 - boric acid - 6 - base) naphthalene storage is exposed, contact with air and other external factors, accelerate its deterioration, just like glass is fragile, and it will become powder without a little attention.
Therefore, to store 2 - (5 - boric acid - 6 - base) naphthalene storage, you need to find a cool, dry, dark and clean place, and beware of vibration and collision, in order to protect its quality and store its medicinal power for emergencies.
What is the price range of 2- (5-bromoquinoxaline-6-yl) guanidine in the market?
Today, there is a price of two minus (five minus glazed luminous light - six bases). What is the price range in the market? Let me analyze it in detail.
The price of glazed luminous things often varies depending on factors such as quality, workmanship, and market conditions. In the ancient market, merchants set prices according to their scarcity, or according to the simplicity of craftsmanship.
If this glazed luminous light is pure in quality and is very scarce, and the value added by the six bases is significant, in a prosperous city, it may reach thousands of gold. The price of five minus this glazed luminous light - six bases is still above a few hundred gold, and the price of two minus is still above the remaining hundred gold.
If the quality is not good, the work is normal, and the stock in the city is large, the price of five minus this glazed luminous light - six bases, or only a few tens of gold, two minus, or only a few gold.
And the market conditions are fickle. In times of abundance, the people are prosperous, and the price of good things may rise; in times of disaster, people's livelihood is difficult, and the price of all kinds of things may also drop. It is based on the price range of two minus (five minus glazed luminous light - six bases) in the market. It is difficult to determine whether it is low or a few gold, and the high can reach a hundred gold. It depends on many factors.
