5,6-Dihydro-2-methylbenzofuran is an organic compound. Although its synthesis method is not directly mentioned in Tiangong Kaiwu, it can be discussed as follows by the idea of ancient chemical technology.
To make this substance, you can start from a natural substance containing benzene ring and furan structure. In ancient times, there were methods to extract various components from plants, such as distillation and extraction to separate substances. Plants rich in similar structures can be found. After drying and shredding, water or wine is used as a solvent and impregnated for a long time to dissolve the active ingredients. After that, the solvent is separated from the ingredients by distillation to obtain a preliminary extract.
Furthermore, in organic synthesis, the introduction and transformation of groups is very important. To introduce methyl groups, although there were no modern advanced reagents in ancient times, they could try to react with natural methyl-containing substances. For example, some vegetable oils or fermentation products contain methyl groups, which can react with preliminary extracts under specific conditions. In terms of conditions, heating is a common method. It can be slowly heated in ceramic or metal containers with charcoal fire to promote the reaction. However, the heating temperature needs to be carefully controlled. If it is too high, the reactants will decompose, and if it is not too low, the reaction will be difficult.
At the same time, the structure of furan rings can be constructed, or the principle of condensation reaction can be used. Although there is no modern thorough understanding of the reaction mechanism in ancient times, it can be explored in practice. If a suitable carbonyl and hydroxyl compound is selected, the ratio of the two and the pH of the reaction environment need to be tried continuously. The environment can be adjusted by the alkaline components of natural acids, such as acetic acid, or alkalis, such as plant ash. After many attempts, the appropriate reaction ratio and environment were found to make the compound condensate to form a furan ring.
And because the reaction product is often impure, it needs to go through refining steps. In ancient times, there was a method of recrystallization. The crude product was dissolved in a suitable solvent, heated and dissolved, slowly cooled, and the pure crystals were precipitated, and the impurities were left in the mother liquor. Repeated many times, the purer 5,6-dihydro-2-methylbenzofuran could be obtained.

5,6-Dihydro-2-methylbenzofuranone, this physical property is complex, let me talk about it in detail.
It has the sign of color state, and it is mostly colorless to light yellow liquid under normal circumstances. The texture is clear, like a clear spring in the mountains. The view is transparent, but it is also slightly yellow, just like the first photo of the morning, with a unique color and charm.
Smell it, the smell is unique, and there is an elegant fragrance, just like a spring flower, fragrant but not rich, delicate and recognizable, and the faint aroma lingers on the tip of the nose, which is impressive.
When it comes to the melting boiling point, the melting point is very low, just like thin ice in winter, when it is warm, it will become invisible; the boiling point is higher, just like the towering peak, which needs to go through a lot of heat before it can be vaporized. This property is due to the interaction between molecules. Its structure is exquisite, and the attractive force and repulsion force between molecules are balanced, creating such a state of melting and boiling.
There is also a wonderful thing about solubility. In organic solvents, such as ethanol and ether, it is like a wanderer returning home, and it is very easy to blend, and it is indistinguishable from each other. However, in water, it is like oil and water, and it is difficult to blend. Due to the difference in molecular polarity, it is very different from the polarity of water, so it is difficult to dissolve. < Br >
The density is moderate, it does not float or sink, and it is placed in a liquid, and it has its own position. It is not as good as a light feather floating up or sinking like a heavy stone. Compared with the density of common liquids, it is unique, and it shows its characteristics in the mixing and separation of substances.
In the field of organic synthesis, this substance is like a weapon in the hands of a skilled craftsman, and it has an extraordinary effect. Due to its unique physical properties, it is often a key intermediate in the synthesis of complex organic compounds. It participates in many chemical reactions, just like the cornerstone of building a magnificent building. In the hall of organic chemistry, it holds up a sky and promotes the development of organic synthesis.

5% 2C6-dioxy-2-methylbenzofuran must pay attention to the following matters during use:
First, it is related to storage. This substance should be properly stored in a cool, dry and well-ventilated place. It must not be placed in direct sunlight, due to light or cause its properties to change. It should also be kept away from fire and heat sources to prevent the risk of fire. At the same time, it must be separated from oxidants, acids, bases and other substances to avoid chemical reactions.
Second, discuss the rules of operation. When operating, be sure to ensure that it is carried out in a fume hood to ensure air circulation in the working environment and reduce the accumulation of harmful gases. Operators should wear appropriate protective clothing, protective gloves and goggles and other equipment to prevent direct contact with the skin and eyes. If they come into contact, they should immediately rinse with a large amount of water and seek medical treatment in a timely manner. During the operation, the action should be steady and slow to avoid the leakage of the substance. In the event of a spill, irrelevant personnel should be evacuated quickly and access should be strictly restricted. Emergency personnel should wear proper protective equipment and do not let the spill come into contact with combustible substances. Small spills can be absorbed by inert materials such as sand and vermiculite; large spills need to be built into embankments or excavated for containment, and transferred to a tank or special collector by pump, recycled or transported to a waste treatment site for disposal.
Third, the rules about transportation. Before transportation, make sure that the packaging is complete and sealed. During transportation, make sure that the container does not leak, collapse, fall or damage. Follow the specified route and do not stop in residential areas and densely populated areas.
