Its physical properties are as follows:
In appearance, it is mostly colorless to light yellow liquid at room temperature. In some cases, the color may be slightly different due to purity or impurities.
In terms of odor, it has a special irritating odor. This odor is unique and can be clearly perceived by close to a fine smell.
The melting point is about -20 ° C to -10 ° C. Under this temperature range, the substance will change from liquid to solid.
The boiling point is about 170 ° C to 180 ° C. When the temperature reaches this range, the substance will be vaporized from liquid to gaseous.
The density is usually higher than that of water, about 1.6-1.8g/cm ³. After mixing it with water, it will sink to the bottom of the water.
In terms of solubility, it is slightly soluble in water, but easily soluble in common organic solvents, such as ethanol, ether, acetone, etc., and can be well dispersed and dissolved in these organic solvents.
In addition, the vapor pressure of this substance is relatively low at room temperature and the volatility is weak, but as the temperature increases, the vapor pressure will increase and the volatility will increase. Due to the presence of fluorine and chlorine atoms in its molecular structure, this substance has certain chemical stability, and also has some typical physical properties of halogenated aromatics.

1% 2C2% 2C3% 2C5-tetraene-4% 2C6-dialkynaphthalene has unique chemical properties. This compound contains multiple unsaturated bonds, which makes it highly reactive.
As far as the addition reaction is concerned, it is easy to add with electrophilic reagents such as hydrogen halide and halogen due to the existence of alkylene bonds and alkyne bonds. Taking bromine as an example, it can be added with alkyne bonds to make the reddish brown of bromine fade away. This is a common method for testing unsaturated bonds.
Because of its conjugate structure, it has certain stability and special electronic effects. The conjugate system delocalizes electrons and affects the physical and chemical properties of compounds. For example, in the ultraviolet-visible spectrum, there will be characteristic absorption peaks, due to the π - π* transition of the conjugated system.
In the oxidation reaction, it can be oxidized by strong oxidants such as potassium permanganate, and the alkyne bond is broken. Different oxidation products are formed depending on the reaction conditions and the amount of oxidant.
In addition, 1% 2C2% 2C3% 2C5-tetraene-4% 2C6-dialkynaphthalene The electron cloud distribution is uneven, and the electron cloud density of alkynyl groups and alkenyl groups is different, so that in the nucleophilic substitution reaction, different positions exhibit different reactivity. Due to its structural particularity, it can be used as a key intermediate in the field of organic synthesis to construct complex organic molecular structures.

First, the use of medicine. 1%2C2%2C3%2C5-%E5%9B%9B%E6%B0%9F-4%2C6-%E4%BA%8C%E7%A2%98%E8%8B%AF%E7%9A%84%E6%B0%9F%E5%88%86%E4%B8%8D%E5%90%8C%E5%8F%8A%E7%82%B9%E7%82%B9%E7%9A%84%E7%BB%93%E6%9E%84%E7%89%B9%E7%82%B9%EF%BC%8C%E4%B8%BA%E4%B8%AD%E5%8C%BB%E8%8D%AF%E7%90%86%E7%96%91%E6%89%80%E7%9F%A5%E3%80%82%E4%B8%AD%E5%8C%BB%E4%B9%9F%E8%83%BD%E5%88%A9%E7%94%A8%E5%85%B6%E7%89%B9%E6%80%A7%E4%BC%98%E7%82%B9%EF%BC%8C%E8%8E%B7%E5%8F%96%E5%88%9B%E6%96%B0%E7%9A%84%E8%8D%AF%E7%90%86%E6%96%B9%E6%B3%95%EF%BC%8C%E4%BD%9C%E7%94%A8%E4%BA%8E%E4%BA%BA%E4%BD%93%EF%BC%8C%E8%A7%A3%E5%86%B3%E4%B8%80%E4%BA%9B%E7%97%85%E7%97%87%E9%97%AE%E9%A2%98%E3%80%82
Second, the use of work. In ancient times, craftsmen studied the properties of various materials very deeply. 1%2C2%2C3%2C5-%E5%9B%9B%E6%B0%9F-4%2C6-%E4%BA%8C%E7%A2%98%E8%8B%AF%E7%9A%84%E4%B8%93%E6%A0%87%E7%89%B9%E6%80%A7%EF%BC%8C%E5%8F%AF%E8%83%BD%E5%90%91%E5%B7%A5%E5%8C%A0%E6%8F%90%E4%BE%9B%E6%96%B0%E6%9D%90%E6%96%99%E6%80%9D%E8%B7%AF%E3%80%82%E5%B7%A5%E5%8C%A0%E5%8F%AF%E5%88%A9%E7%94%A8%E5%85%B6%E7%89%B9%E6%80%A7%EF%BC%8C%E5%88%B6%E4%BD%9C%E5%87%BA%E6%9C%89%E7%89%B9%E6%80%A7%E7%9A%84%E5%B7%A5%E5%85%B7%E6%88%96%E5%93%81%E7%89%8C%EF%BC%8C%E5%A4%9F%E8%B5%84%E4%BA%BA%E4%BB%A5%E4%BF%9D%E5%AE%89%E3%80%81%E5%8A%A9%E5%8A%9F%E3%80%82
Third, the way of alchemy. Ancient alchemists pursued the exploration of various material mysteries between heaven and earth. 1%2C2%2C3%2C5-%E5%9B%9B%E6%B0%9F-4%2C6-%E4%BA%8C%E7%A2%98%E8%8B%AF%E7%9A%84%E7%89%B9%E6%80%A7%E5%AF%B9%E4%BA%8E%E6%96%B9%E6%9C%AF%E4%B9%8B%E5%A3%B0%E7%9F%A5%E8%BF%9B%E9%98%B6%E6%9C%89%E5%88%86%E5%B8%83%E7%9A%84%E5%8A%9F%E7%94%A8%E3%80%82%E5%8F%AF%E8%83%BD%E5%90%91%E6%96%B9%E6%9C%AF%E4%B8%93%E4%B8%9A%E8%80%85%E6%8F%90%E4%BE%9B%E6%96%B0%E7%9A%84%E7%90%86%E8%AE%BA%E6%9D%90%E6%96%99%EF%BC%8C%E4%BD%9C%E4%B8%BA%E5%88%9B%E6%96%B0%E6%96%B9%E6%B3%95%E4%B8%8E%E6%8A%80%E5%B7%A7%E7%9A%84%E5%9F%BA%E7%A1%80%EF%BC%8C%E5%85%B6%E5%AF%B9%E4%BA%8E%E4%B8%96%E9%97%B4%E7%9A%84%E7%90%86%E8%A7%A3%E4%B8%8E%E6%8E%A2%E7%B4%A2%E4%B9%9F%E8%83%BD%E5%8F%91%E6%89%A9%E3%80%82

1%2C2%2C3%2C5-%E5%9B%9B%E6%B0%9F-4%2C6-%E4%BA%8C%E7%A2%98%E8%8B%AF%E7%9A%84%E5%90%88%E6%88%90%E6%96%B9%E6%B3%95%E5%8F%AF%E6%98%AF%E4%BB%A5%E4%B8%8B%E6%96%B9%E5%BC%8F%EF%BC%9A
First, take an appropriate amount of raw materials, such as Salvia miltiorrhiza, Chuanxiong, Angelica, etc., which are all medicinal herbs commonly used by physicians. Wash and dry Salvia miltiorrhiza, cut it into thin slices with a knife and set aside for later use. Chuanxiong is also treated in this way, carefully cut into small sections, so that its medicinal properties are easy to precipitate. Angelica needs to be carefully selected to remove impurities, and then cut into sections for later use.
Take a clean casserole. This casserole is mild in nature and can ensure that the taste of the drug does not dissipate. Put the cut Salvia miltiorrhiza slices, Chuanxiong segments, and Angelica segments into the casserole in turn. Then, inject an appropriate amount of water. The amount of water depends on the amount of medicine and the concentration of the required liquid, not too much or too little. In general, it is advisable to have less than one inch of the medicine.
Place the casserole over a low heat and slowly heat it up. At first, the heat should slow down to allow the medicine to gradually merge with the water. Wait for the water to be slightly warmer, turn it to medium heat, and let it boil slightly. At this time, you can see that there are small bubbles on the water surface, and the aroma of the medicine gradually escapes.
Keep simmering on medium heat for about half an hour, stirring gently with a wooden spoon from time to time, so that the medicine is heated evenly and the medicinal properties are fully fried. When simmering until the color of the liquid medicine gradually darkens, such as the luster of amber, and it emits a rich medicinal fragrance, remove the casserole.
Filter out the liquid medicine with a fine filter to remove the residue. The filtered liquid is the finished product of 1%2C2%2C3%2C5-%E5%9B%9B%E6%B0%9F-4%2C6-%E4%BA%8C%E7%A2%98%E8%8B%AF%E7%9A%84%E5%88%9D. It can be taken according to the disease and the doctor's instructions, either warm or cold, to achieve the best curative effect. However, the way of medication needs to be done with caution. If there is any carelessness, fear of other changes, and do not ignore it.

1% 2C2% 2C3% 2C5-tetraene-4% 2C6-diyne steroids need to pay attention to many matters during storage and transportation. The chemical properties of this steroid are more active, because its structure contains multiple unsaturated bonds, which can easily cause structural changes when exposed to light. Therefore, storage should be placed in a light-shielded container, away from light. Temperature is also a key factor. High temperature may cause steroids to decompose or polymerize. Generally, it should be stored in a cool place. The temperature should be controlled within a specific range to prevent deterioration.
Furthermore, humidity cannot be ignored. Humid environment may cause it to absorb moisture, which will affect the quality. Therefore, storage should be kept dry. When transporting, it is necessary to ensure that the packaging is tight to prevent the steroid from coming into contact with the external environment. Due to its certain chemical activity, it should be avoided to mix with oxidizing and reducing substances during transportation to prevent chemical reactions from occurring, causing it to fail or cause danger.
In addition, the steroid needs to be handled with care during handling, and the structural stability may be affected due to vibration and collision. Record the storage and transportation conditions in detail for traceability and supervision. Once any abnormalities are found, they can be dealt with in time, so as to ensure the quality and stability of 1% 2C2% 2C3% 2C5-tetraene-4% 2C6-diyne steroids during storage and transportation.
