Historical Development
DL-Menthol, commonly used in medicines and fragrances. Examining its origin, the ancient ancestors gradually felt the coolness of mint among plants and trees, and the essence of this is that it contains DL-Menthol. In the past, people relied on experience and used mint to relieve annoying heat.
In modern times, science and technology have advanced day by day. Chemists analyze the composition of mint, and understand the structure of DL-Menthol. Then chemical methods were used to make this substance, and the yield increased gradually, and the application became more and more widespread. At first, it only treated diseases, but later it was found in daily chemicals and food. Looking at the path of its development, from natural mining to artificial integration, from simple to complex, it is the fruit of the combination of technology and wisdom. In this world, it is still an indispensable thing for all karma.

Preparation Method
DL-Menthol, there is a way to make it. Its raw materials are taken from various natural things, or combined with chemical methods. Natural, extracted from mint, but the amount is small and expensive. The way of chemical synthesis begins with isoprene, etc.
The process of its production is first condensed with isoprene and formaldehyde to obtain the key intermediate. Then, through multi-step reactions, such as hydrogenation and cyclization, its structure is adjusted. After splitting, DL-Menthol is obtained. For splitting, use chiral reagents to separate the enantiomers.
Reaction conditions, temperature, pressure and catalysis are required. Appropriate temperature can promote the speed of reaction, combined pressure can keep the stability of the material state, and good catalyst can reduce the energy of activation. In this way, following this process, DL-Menthol can be prepared to meet the needs of medicine and daily chemicals.

What are the physical properties of DL-Menthol?
DL-menthol is an organic compound with many physical properties. Its properties are colorless needle-like crystals or granules, which exist stably at room temperature, and appear transparent to white when viewed. This is its appearance characteristic.
When it comes to the melting point, the melting point is between 31 ° C and 34 ° C, and the boiling point is between 216 ° C and 217 ° C. This melting boiling point characteristic makes it possible to realize the transformation of solid and liquid states under specific temperature conditions.
DL-menthol has a unique smell, a cool and strong mint aroma, which is rich and recognizable. In terms of solubility, it is slightly soluble in water, but soluble in organic solvents such as ethanol, ether, and chloroform. This difference in solubility is due to its molecular structural properties, which make it interact differently with different solvents.
Furthermore, the density is about 0.890g/cm ³, indicating that it has a specific mass per unit volume. Its optical rotation is 0 °, because DL-menthol is a racemate, composed of equal amounts of left-handed and right-handed bodies, and the optical rotation cancels each other.

What is the production process of DL-Menthol?
DL-menthol is the main active ingredient in menthol, and its preparation process is exquisite. Natural menthol is often used as the starting material and obtained through many steps.
The first step is to choose high-quality natural menthol, which is mostly extracted from menthol plants. This is the foundation of the process. After chemical treatment, acid or alkali is often used as the medium to change the structure of menthol. If treated with a specific concentration of sulfuric acid, the molecule is rearranged, and the structure is more suitable for subsequent reactions.
In the next step, the rearranged product is entered into the separation process. The target product is separated from the self-reactive mixture by distillation, extraction, etc. During distillation, according to the difference in the boiling point of each component, the target product is vaporized and condensed to collect; extraction uses different solvents with different solubility to extract the target component.
Another step is to obtain the crude product and then refine it. Most of them are prepared by crystallization method, select an appropriate solvent, heat and dissolve the crude product, cool down to make the crystal precipitate, remove impurities, and improve the purity.
Another synthetic method is prepared. Using m-cresol as the starting material, it first reacts with isobutylene to form a key intermediate. The reaction requires a specific catalyst and temperature and pressure conditions. For example, under the action of a suitable temperature and catalyst, m-cresol reacts efficiently with isobutylene.
Intermediates are then hydrogenated and cyclized to gradually build the molecular structure of menthol. During hydrogenation, the amount of hydrogen and reaction conditions are precisely controlled to saturate the unsaturated bond hydrogenation.
Synthetic products also need to be separated and refined to meet the required purity standards. The entire DL-menthol preparation process is closely interlocked, and the conditions are strictly controlled to obtain high-quality products.

What is the price range of DL-Menthol in the market?
In the market, the price range of DL-menthol often varies depending on quality, quantity and market conditions. In the past, the price may have ranged from tens to hundreds of yuan per kilogram. If the quality is high and the supply is less and the demand is more, the price will increase; if the quality is flat and the supply is sufficient and the demand is small, the price will decrease.
In the past, in various cities, it was common for the price of DL-menthol per kilogram to be around 50 yuan, and it would even reach 200 yuan. The change in this price is really related to the abundance of production and the urgency of demand. The production area is abundant every year, and the market supply is full, so the price will be stable and decline; if the production area is in disaster, the production will decrease and the supply will be less, and the demand of all parties will be cut, and the price will jump.
And the way of trade, the quantity is also the price. If the buyer wants a large quantity, the business may be for profit, and the discount is allowed, and the price is lower than that of retail sales; if the quantity is small, the price will not be greatly reduced.
Therefore, if you want to know the exact price of DL-menthol, you must carefully observe the current market conditions, and visit merchants and producers to obtain the actual price. It is difficult to generalize the scope of its price.

What to pay attention to when using DL-Menthol
For DL-menthol, pay attention to all things when using it. First of all, its nature is cool and its smell is cold, so the dosage must be cautious. Although it has the power of clearing wind and heat, removing filth and detoxifying, overuse may damage the righteousness. If used externally, it is necessary to carefully examine whether the skin is damaged. If there is a wound, use it may cause pain and discomfort, or even lead to evil poison, making the wound difficult to heal.
In addition, its smell is strong, and it should be used in a closed space. Pay attention to ventilation. If the smell is too long or too strong, or it may cause dizziness, nausea, etc. Because the smell is strong, it disturbs emptying.
When taking it internally, be especially cautious. It is necessary to follow the doctor's instructions and measure accurately. Due to different individual endowments, tolerance to it varies. The young, the elderly and the infirm should be tested gradually in small quantities to prevent severe sexual damage to the viscera. And when taking it internally, avoid eating it with the medicine of Xiangke to avoid changes.
Furthermore, storage is also important. It should be placed in a cool and dry place, protected from heat and light. If it is placed in a high temperature and humid place, or its characteristics are mutated, the original effect will be lost. In short, the use of DL-menthol must be carefully examined and followed by its advisability and taboo, in order to obtain its benefits and avoid its harm.
