What are the physical properties of 9,9-bis (methoxymethyl) fluorene?

The physical properties of 9,9-bis (acetoxy methyl) nonene are as follows:

The form of this substance is mostly liquid at room temperature and pressure. Looking at its color, it is usually colorless and transparent, and if it contains impurities, it may have a yellowish color. It has a certain fluidity and is similar to common oily liquids to the touch.

Smell its smell and emit a slight and special organic smell. Although it is not strong and pungent, it can still be detected in detail.

When it comes to solubility, this substance exhibits good solubility in organic solvents, such as ethanol, ether, acetone and other common organic solvents, which can be mixed with it to form a uniform solution. However, in water, its solubility is quite low, almost insoluble, because there are few hydrophilic groups in its molecular structure, and the hydrophobic alkyl chain is longer.

Its density is slightly smaller than that of water. If it is placed in a container with water, it can be seen that it floats on the water surface.

Boiling point and melting point are also important physical properties. Its boiling point is relatively high, and it needs a certain temperature to change from liquid to gaseous state; its melting point is relatively low, and it is in a liquid state at room temperature. The specific melting boiling point value will vary slightly depending on the purity of the substance and the experimental measurement conditions. < Br >
In addition, the refractive index of the substance also has a specific value, and the corresponding refraction phenomenon occurs when light passes through. This property is of great application value in the fields of substance identification and purity analysis. Its surface tension is moderate, which also has a corresponding impact on the dispersion and wetting properties of the substance.

Is the chemical stability of 9,9-bis (methoxymethyl) fluorene?

The chemical properties of 9,9-bis (acetoxy methyl) nonyl are relatively stable. Among this compound, the acetoxy methyl structure endows it with a certain degree of chemical inertness. In the acetoxy group, the oxygen atom forms a conjugated system with the carbonyl group, making it difficult for this part of the structure to react. As a power supply group, methyl also contributes to the overall structural stability.

The long chain structure of nonyl is relatively stable, and the carbon-carbon single bond can rotate around the axis, making the molecular chain have a certain flexibility. However, due to its long carbon chain, the overall chemical activity is low.

From the perspective of reactivity, this compound usually does not react violently spontaneously. However, under certain conditions, such as high temperatures, strong acid bases, or the presence of specific catalysts, acetoxy groups may undergo hydrolysis reactions to generate corresponding alcohols and acids. However, under conventional conditions, its chemical properties can be maintained in a stable state, and it is not easy to react with common substances. It can exist relatively stably in an environment at room temperature and pressure.

What is the synthesis method of 9,9-bis (methoxymethyl) fluorene?

The synthesis method of 9,9-bis (acetoxy methyl) acetaldehyde is as follows:

First take an appropriate amount of formaldehyde solution, place it in a clean reactor, and slowly stir at low temperature. In this process, glyoxal is added dropwise to control the dropwise rate to ensure that the reaction proceeds mildly. After formaldehyde and glyoxal are fully mixed, heat up to a suitable temperature. This temperature needs to be precisely controlled. Too high or too low will affect the reaction process and product purity.

Next, add an appropriate amount of acetic anhydride as an acylating agent. The amount of acetic anhydride needs to be prepared in a specific ratio according to the amount of formaldehyde and glyoxal. After the addition of acetic anhydride, the reaction system will undergo an acylation reaction. At this time, continuous stirring is required to make the reactants fully contact and accelerate the reaction.

During the reaction process, closely monitor the temperature, pH and other parameters of the reaction system. When the reaction is carried out to a certain extent, use suitable analytical methods, such as thin layer chromatography (TLC), to monitor the reaction process to determine whether the reaction is complete.

After the reaction is completed, the reaction product is post-processed. First, the method of reduced pressure distillation is used to remove excess solvents and unreacted raw materials in the reaction system. Then, the crude product is purified by column chromatography or recrystallization to obtain high-purity 9,9-bis (acetoxy methyl) acetaldehyde.

During the entire synthesis process, it is necessary to strictly follow the experimental operating procedures, pay attention to safety, and prevent danger caused by improper operation. At the same time, careful regulation of reaction conditions can ensure the efficient and smooth progress of the synthesis reaction and obtain high-quality target products.

What is the price range of 9,9-bis (methoxymethyl) fluorene in the market?

The price range of 9% 2C9 -bis (methoxy methyl) ether in the market is related to many reasons. This substance is widely used in the field of organic synthesis, often used as a protective group, and also involved in medicine, materials and other industries.

The change in its price is primarily supply and demand. If the demand for it in the pharmaceutical and other industries suddenly increases, the supply is not enough, and the price will rise. On the contrary, if the demand is small and the supply is abundant, the price may drop.

The second is the raw material. The production of this ether requires raw materials. If the price of raw materials is high, its production cost will increase, and the market price will also be high; if the price of raw materials falls, its price will also follow.

Furthermore, the process and production capacity. If the process is good, the production capacity increases, the unit cost decreases, the price or low. The new technology is not mature, the production is hindered, and the price may be high.

Repeat, political regulations and trade. Environmental protection is harsh, the cost of production increases, and the price rises; trade barriers are set up, supply is blocked, and the price also rises.

In today's market, the price of 9% 2C9-bis (methoxy methyl) ether is about hundreds to thousands of yuan per kilogram. However, this is only an estimate. The price varies greatly depending on the time and place. In the distribution center of chemical raw materials, the price may be low; in remote places, plus the cost of transportation, the price may be high. To confirm the price, it is advisable to consult the supplier, or refer to the latest offer on the chemical trading platform.
