1,3-thiazole-2-sulfonyl chloride

2 - Xenon, neon and argon are all inert gases. Their physical properties are unique, let me come one by one.
Xenon is colorless and odorless, and is gaseous under standard conditions. Its density is heavier than air, about 5.89kg/m ³. Melting point -111.9 ° C, boiling point -108.1 ° C. This gas has a high critical temperature and critical pressure, 16.6 ° C and 5.84 MPa respectively. Xenon can emit beautiful blue light under electric field excitation, so it is often used to make special light sources, such as xenon lamps.
Neon is also a colorless and odorless gas. The density is less than air, about 0.9002kg/m ³. Melting point -248.67 ° C, boiling point -246.08 ° C. Its critical temperature is -228.7 ° C, and the critical pressure is 2.76MPa. When neon gas is excited in the discharge tube, it will emit a bright orange-red light. The neon lights that are common in life are mostly colorful due to the filling of neon gas.
Argon is also colorless and odorless. The density is slightly higher than that of air, about 1.784kg/m ³. Melting point -189.2 ° C, boiling point -185.7 ° C. Critical temperature -122.4 ° C, critical pressure 4.86MPa. Argon is chemically very stable and is often used as a protective gas to prevent metal from oxidizing when welding.
All three are gases composed of single atomic molecules, and the intermolecular force is weak, which is the reason for their low melting and boiling point. And because of its inertness, it is not easy to chemically react with other substances, so it has unique applications in many fields. From the perspective of their physical properties, they play an indispensable role in industry, scientific research, lighting and many other aspects.

1% 2C3 - Realgar - 2 - The chemical properties of orpiment, toxic and reactive properties. Realgar, its color is as red as a chicken crown, and it is brittle and fragile. It is hot in nature and toxic, and contains arsenic sulfide. Calcined in fire, it can produce highly toxic arsenic, and it will also produce sulfur dioxide gas, which is its danger. Orpiment, golden in color, is soft, and also contains arsenic sulfides. Its nature is also toxic, but its toxicity is slightly lighter than that of realgar. Both are important mineral medicines, but they should be used with caution, because their toxicity can endanger life. And in the chemical reaction of the two, they will react with acids, bases, etc. due to the specific reactions they contain, and form new substances. In case of strong acid, hydrogen sulfide gas can be produced, which smells like rotten eggs. This is one of the ways to identify the chemical changes of the two. When using medication to treat diseases, be sure to check its properties carefully, follow ancient teachings, and use it cautiously to prevent side effects of poisoning.

The main uses of 1% 2C3-Musk-2-Realgar are as follows:
Musk, which is an extremely valuable spice and medicinal material. In the way of spices, its aroma is unique and rich and lasting, which can make the fragrance rich in layers, elegant and deep, so it plays a key role in many high-end perfumes, which can make the aroma more unique and charming. On the medicinal level, musk has the effect of opening the mind to wake up, and it has a significant effect on diseases such as coma caused by evil enlightenment of the mind. Like stroke, phlegm, gas syndromes, etc., musk often opens the mind to wake up. And it has the power of promoting blood circulation and passing menstruation, which can be used to treat blood stasis, menstrual closure, accumulation of crucibles and other obstetrics and gynecology blood stasis diseases; it can also reduce swelling and relieve pain, and it has good curative effect on carbuncle and sore poison, scrofula sputum nucleus, sore throat and slump injury, blood stasis and swelling pain, etc.
Realgar, mainly used for detoxification and insecticide. It can dry dampness and remove phlegm and cut malaria. In the case of sore carbuncle and swelling, it can be used externally to detoxify and reduce swelling, and is often used in combination with other detoxifying drugs. In the treatment of insect and snake bites, external application of realgar can detoxify the In the traditional application of traditional Chinese medicine, realgar also has a certain anti-malaria effect on malaria. Although the clinical application is relatively reduced today, it still has a place in specific diseases and traditional formulas. At the same time, in some traditional folk activities, such as the Dragon Boat Festival, people will sprinkle realgar around the house or drink realgar wine to achieve the meaning of repelling evil spirits and insects.

There are many methods for synthesizing 1% 2C3-musk-2-salicylic acid, among which the door is quite deep. Let me come to you one by one.
Musk has a rich aroma and is a precious fragrance and medicinal material. However, it is difficult to obtain natural musk, so artificial synthesis is of great significance. To synthesize musk, it is necessary to use the method of organic chemistry to obtain suitable raw materials through multi-step reactions.
Common synthesis routes, with m-xylene as the starting material, are many. M-xylene is nitrified, nitro is introduced, and then reduced to convert the nitro group into an amino group. Then through a series of reactions such as diazotization and hydrolysis, key intermediates can be prepared. After that, with specific reaction conditions and reagents, further conversion is obtained, and finally musk compounds are obtained. In this process, the control of the reaction conditions is extremely critical, and a slight difference in temperature and pH will affect the purity and yield of the product.
As for salicylic acid, there are also various paths for its synthesis. The classic method uses phenol as a raw material, reacts with sodium hydroxide to form sodium phenol, and then reacts with carbon dioxide at a specific pressure and temperature to form sodium salicylate, which can be obtained by acidification. This method is called the Kolbe-Schmidt reaction. Although the process is mature, the reaction conditions are harsh and the equipment requirements are high.
There are also those who use o-cresol as a raw material. Salicylic acid can be prepared by oxidation reaction, which first oxidizes the methyl group to the carboxyl group, and then rearranges the reaction. This route is relatively simple, but the selective control of oxidation and rearrangement reactions requires fine operation to obtain high-purity products.
Synthesis of 1% 2C3-musk-2-salicylic acid can be selected according to actual needs, raw material availability and cost considerations. And during the synthesis process, attention must be paid to the optimization of reaction conditions and product purification to achieve the desired effect.

1% 2C3 - Mercury Vapor - 2 - The developer needs to pay attention to the following things when storing and transporting:
First, it is related to storage. Find a cool and dry place to place the developer. Because it contains many chemicals, if it is placed in a high temperature and humid place, it is easy to cause the components to deteriorate and the efficacy of the medicine is greatly reduced. For example, in midsummer, if the developer is placed in a place with hot sun and heavy moisture, it may become turbid soon, and the medicinal power will also decline, resulting in poor development effect. And it should be kept away from fire and heat sources. Many components in the developer are flammable or chemically active. Near the fire source heat source, it is afraid of fire or chemical reactions, endangering safety.
Second, about transportation. The packaging must be stable and solid. Due to the inevitable bumps and vibrations during transportation, if the packaging is not solid, the developer will easily leak. If the vehicle vibrates frequently during long-distance transportation, if the container is not tightly sealed and the material is not firm, the developer may seep out and defile other objects, and it will also lose itself. Furthermore, pay attention to isolation from other items during transportation. The developer may chemically react with certain substances, such as mixing with acidic or alkaline substances, or dangerous, so it must be placed separately to prevent accidents.
And mercury vapor, when storing, make sure that the container is well sealed, because it is easy to evaporate, and if there is a slight gap, mercury vapor will escape, pollute the environment and endanger the human body. Be extra cautious when transporting. Once leaked, mercury vapor will spread rapidly, be highly toxic and difficult to clean. In addition to being firmly sealed, the packaging should also have the ability to prevent breakage and extrusion, and the entire transportation process should be strictly monitored to prevent mercury vapor leakage from being detected and causing serious consequences.
