2-% pentyne ethanol is an organic compound with unique chemical properties. Its molecule contains carbon-carbon triple bonds and hydroxyl groups, which give the substance a variety of reactivity.
First talk about the properties of its alkynyl group. Carbon-carbon triple bonds are rich in electrons, have high reactivity, and are prone to addition reactions. Taking the reaction with halogens as an example, electrophilic addition can be carried out. In case of bromine water, the bromine molecule is attracted by the electron cloud of alkynyl groups, and the addition occurs. The triple bond becomes a double bond, and the bromine-containing olefin derivative is formed. The reddish brown of the solution fades. This is a common method for testing carbon-carbon triple bonds. And under the action of a specific catalyst, it can be added with hydrogen. Added to an olefin first, and continued to react to form alkanes And because of its alkynyl hydrogen has a certain acidity, under the action of strong alkali, it can be replaced by metal ions to form alkynyl metal compounds. This compound is an important intermediate in organic synthesis and can participate in many carbon-carbon bond formation reactions.
Again look at its hydroxyl properties. The hydroxyl group gives 2-% pentylethanol typical properties of alcohols. It can react with active metals such as sodium to replace hydrogen and generate sodium alcohol. Under the heating condition of concentrated sulfuric acid, an elimination reaction can occur. The hydroxyl group combines with hydrogen atoms on adjacent carbons to form water and dehydrates to form carbon-carbon double bonds. The product may be a conjugated olefin, which has special stability due to the existence of a conjugated system. At the same time, the hydroxyl group can participate in the esterification reaction, and the carboxylic acid can be catalyzed by concentrated sulfuric acid to form esters and water. This reaction is reversible, and the ester yield can be improved by controlling the conditions.
2-% pentyne ethanol exhibits rich chemical reactivity due to the coexistence of alkynyl and hydroxyl groups, and has important application value in the field of organic synthesis, providing a variety of possible paths for the preparation of complex organic compounds.

The first is the millet of good quality, and choose the one that is full and flawless. The millet is the length of the grain, and its nature is mild, so it should be the foundation of brewing.
Wash the millet clean, and the water is clear and clear. Then soak it in water, and observe the weather of its day. Soak it for about two hours in warm times, and a little longer in cold times, so that the millet is moist and not too soft.
Soak it, drain it, and steam it in a retort. The retort, the ancient cooking utensil, made of bamboo or pottery, can make the heat flow around, and the millet is ripe and uniform. When steaming, stir it up with a fierce fire, wait for the steam to rise, and then simmer it over a low fire, so that the millet is ripe and fragrant.
Ripe millet comes out of the retort, spread it cool on the net mat, and when the temperature is right, touch it with your hands, slightly warm but not hot. At this time, and with the Divine Comedy. The Divine Comedy is the essence of all herbs, and when combined with the grain, it can lead to the wonders of fermentation. The dosage needs to be precise, more strong, less thin.
After mixing, put it in the urn and hide it. The urn should be placed in a remote and cool place to avoid its light and heat, so that the fermentation in the urn can go smoothly. The mouth of the urn is sealed with cloth, and then it is tightly pasted with mud to prevent turbid gas from invading and spoiling its fine wine.
In the urn, millet and koji interact in each other. After several tens of years of work, the liquid gradually comes out of the urn. The color is initially light and then concentrated, and the fragrance is initially hidden and then apparent. Wait for the aroma to overflow, and the fermentation is complete.
At this time, filter the liquid with a cloth to remove the dregs, and obtain the clear liquid is 2-%E5%99%BB%E5%90%A9%E4%B9%99%E8%85%88%E7%9A%84%E7%B2%BE%E9%87%8F%E9%85%92%E6%B6%B2. After the aging period, or half a year, or a year, the purer the wine quality, the sweeter the taste, and the more distant the aroma, the top grade.

2-% pentanal-butyl ester should be stored and stored.
First, the temperature is very important. This compound may be affected by the temperature wave, so it should be used in a cool place to avoid high temperatures. If the temperature is high, it may cause it to accelerate, and even cause the reaction of the reaction, resulting in the reduction of the quantity. Generally speaking, the ideal storage temperature should be kept at 5 to 25 degrees Celsius, and the temperature should be similar on the way, which can be controlled by means of refrigeration.
Second, light should not be ignored. Light irradiation may cause actinic reaction of pentanal-butyl ester, breaking its transformation. Therefore, whether it is stored or not, it should be placed in the dark, such as using dark packaging materials, or stored in a dark room.
Third, the packaging must be damaged. It is necessary to use an appropriate and well-sealed container to prevent leakage. Because valeraldehyde butyl ester has a certain degree of chemical activity, leakage will not cause material loss, which may endanger the safety of people in the environment. The packaging container can withstand a certain amount of force to avoid cracking due to factors such as vibration and deformation.
Fourth, avoid the connection of incompatible materials. Valeraldehyde butyl ester may react to certain oxidizing materials, acids and other substances, so it should not be mixed or mixed in the storage. It needs to be placed in isolation to prevent accidental reactions.
Fifth, keep the tools and tools in the collection clean and dry. The tide environment or temperature may affect the amount of valeraldehyde and butyl ester, which is conducive to its preservation. And the communication is good, in order to prevent the accumulation of water and reduce safety.
