1 - (2 - furanyl) furanaldehyde, also known as furfuran acetone, is an important raw material in organic synthesis. Its physical properties are as follows:
Appearance, at room temperature, 1 - (2 - furanyl) furanaldehyde appears as a yellow to brown liquid, with a unique color, and its special luster can be seen in light.
The boiling point is quite high, about 277 - 278 ° C. Such a high boiling point makes it difficult to vaporize and relatively stable under normal heating conditions. This property is of great significance in the chemical synthesis process involving high temperature reactions, which can ensure that the substance maintains a liquid state in a higher temperature environment and participates in various reactions without easily escaping. The melting point of
is in the range of 39-41 ° C. When the temperature drops near and below the melting point, the substance will change from liquid to solid. This melting point characteristic provides a basis for setting its storage and transportation conditions, and ensures that it is in a suitable physical state within a specific temperature range. The relative density of
is about 1.141 (20/4 ° C), which is slightly higher than that of water. This density difference makes it possible that in the mixed system involving water and 1 - (2-furan-yl) furan-formaldehyde, the two will produce stratification due to different densities, which provides a physical basis for separation and purification operations.
In terms of solubility, it is soluble in many organic solvents such as ethanol, ether, and acetone. This good solubility makes it possible to use these organic solvents as the reaction medium in organic synthesis experiments to promote the full contact and reaction between 1- (2-furanyl) furanaldehyde and other reactants, and improve the reaction efficiency. However, the substance is slightly soluble in water, and this property also affects its separation, purification and related application scenarios. Special consideration should be given to its solubility in the reaction of aqueous systems.

1 - (2 - benzyl) furanaldehyde, also known as furfuryl benzyl ketone, has special chemical properties. Its appearance is often yellow to orange crystalline powder, which is widely used in the field of chemical and pharmaceutical synthesis.
In terms of chemical activity, the aldehyde group and furan ring in this compound give it unique reactivity. The aldehyde group can participate in classical condensation reactions, such as hydroxyaldehyde condensation. Under basic conditions, the α-hydrogen atom of the aldehyde group is acidic and easy to be captured by the base, and then condensate with another molecule of aldehyde or ketone to form a product containing carbon-carbon double bonds, whereby carbon chains can be grown and complex organic structures can be constructed.
Furan ring also has a special electronic effect. Due to the existence of a conjugated system in the ring, the electron cloud density distribution on the furan ring is special. This makes it exhibit unique activity and selectivity in electrophilic substitution reactions. Electrophilic reagents tend to attack the higher electron cloud density sites on the furan ring, providing the possibility for the synthesis of specific substituted derivatives.
In addition, the carbonyl of 1 - (2-benzyl) furanaldehyde can also undergo reduction reactions. Carbonyl can be reduced to alcohol hydroxyl groups by suitable reducing agents, such as sodium borohydride, lithium aluminum hydride, etc. Alcohols with different uses can be derived, providing a variety of paths for organic synthesis, which is of great significance in the preparation of fine chemicals and drug development.

The synthesis methods of 1 - (2 - cyanoethyl) chlorosulfonic acid are as follows:
First, vinyl nitrile and chlorosulfonic acid are used as raw materials. First, an appropriate amount of vinyl nitrile is placed in the reactor, and chlorosulfonic acid is slowly added dropwise at low temperature and in a state of sufficient stirring. This process requires strict temperature control to prevent the temperature from rising sharply and causing side reactions. After adding dropwise, continue to stir for a period of time to make the reaction sufficient. The raw materials of this route are relatively easy to obtain, and the reaction operation is relatively simple. However, the reaction conditions need to be precisely controlled, otherwise the purity of the product will not reach the expected.
Second, acrylonitrile can be prepared by a series of reactions. First, acrylonitrile and a specific reagent undergo an addition reaction to The intermediate product is then reacted with chlorosulfonic acid under suitable conditions to obtain 1- (2-cyanoethyl) chlorosulfonic acid. Although this method is slightly complicated, the requirements for the reaction conditions may be slightly looser, and the yield and purity of the product can be effectively improved by optimizing the intermediate steps.
Third, 2-cyanoethanol is first prepared from chloroethanol and sodium cyanide, and then 2-cyanoethanol is reacted with chlorosulfonic acid. First, chloroethanol and sodium cyanide are reacted in an alkaline environment, and then separated and purified to obtain 2-cyanoethanol. Then 2-cyanoethanol reacts with chlorosulfonic acid at a suitable temperature and in the presence of a catalyst. The raw materials in this way are common, but sodium cyanide is highly toxic. The safety protection must be comprehensive during operation, and the separation and purification after each step of the reaction also requires fine operation to ensure the quality of the product.
All this synthesis method has advantages and disadvantages. In practical application, it is necessary to comprehensively weigh the availability of raw materials, cost considerations, product purity requirements and many other factors, and choose the optimal method to achieve the purpose of high-efficiency and high-quality synthesis of 1- (2-cyanoethyl) chlorosulfonic acid.

1 - (2 -furanomethyl) furanaldehyde, the range of market prices, is related to many factors, and it is difficult to determine the exact number.
The preparation of this substance requires exquisite methods, and the raw materials and processes are all different, and the price is also different. And the supply and demand of the market also affect its price. If there are many people who ask for it, the price will increase if the supply is small; on the contrary, if the supply exceeds the demand, the price may drop.
In addition, its purity is also the key to the price. High purity is difficult to prepare, high cost, and expensive; low purity is relatively cheap. However, the scenarios used are different, and the purity required is also special, so the price range is very wide.
Roughly speaking, ordinary purity, per gram or a few yuan to tens of yuan; if high purity, refined products, the price per gram or more than 100 yuan, or even higher, it is difficult to generalize. And the market price changes at any time, and it needs to be carefully observed in the market to know the real-time price.
