The physical properties of 4-hydroxy- 3-methoxyphenylethanolyl cinnamoyl benzene are as follows:
This color state, at room temperature, is mostly white to light yellow powder, with a fine texture. It looks like fine snow dust, and occasionally shimmers under the sun. Its smell is quite unique, with a light fragrance, not a rich and strong fragrance, just like the deep forest, which inadvertently dissipates the aroma. Smelling it can make people feel more at ease.
When it comes to solubility, in organic solvents, ethanol is quite affinity for it, allowing it to slowly dissolve to form a clear or slightly colored solution; and in ether, it also has a certain solubility, but it is slightly inferior to ethanol. As for water, due to its molecular structure characteristics, this substance is difficult to dissolve in water. If it is placed in water, it is like gravel entering a lake, and most of it sinks to the bottom of the water. Only a very small amount can be mixed with water, causing the water to be slightly milky and turbid.
In terms of melting point, after rigorous measurement, it is around [X] ° C. When the temperature gradually rises to this point, this substance gradually turns from a solid state to a molten state, just like ice and snow in the warm sun, slowly melting. Its density is higher than that of common water. If it is placed in water, it will sink to the bottom of the water, just like gold stones entering water and falling steadily.
In addition, this object is quite sensitive to light and heat. If exposed to strong light for a long time or in a high temperature environment, its molecular structure may quietly change, causing its physical properties to change accordingly, such as the color gradually darkening, from light yellow to dark brown, and the smell will also change, no longer the original elegance, but a little burnt smell. Therefore, when storing, it should be stored in a cool and dark place to prevent its physical properties from mutating.

4-Bifurcation-3-methoxycarbonyl benzyl benzyl benzene is one of the organic compounds. Its chemical properties are quite unique, with specific reactivity and characteristics.
In this compound, its molecular structure contains specific functional groups. Methoxycarbonyl has a certain electronic effect, which affects the overall stability and reactivity of the molecule. The benzylbenzene part gives it a specific spatial structure and chemical activity check point.
In chemical reactions, 4-bifurcation-3-methoxycarbonyl benzylbenzyl can exhibit various properties. Because it contains carbonyl groups, it can participate in reactions such as nucleophilic addition. Nucleophiles easily attack the carbon atoms of carbonyl groups, causing various chemical transformations. For example, the reaction with alcohols or the formation of ester derivatives is very important in the field of organic synthesis and can be used to construct more complex organic molecular structures.
In addition, its benzene ring structure also endows it with aromaticity and can participate in aromatic electrophilic substitution reactions. Under suitable conditions, electrophilic reagents such as halogenating agents and nitrifiers can attack benzene rings and generate corresponding substitution products. This property provides the possibility for the synthesis of functionalized organic materials.
In addition, the cross-structure in the molecule, although the structure is special, will also affect the overall chemical properties. Or affect the stereochemistry of the molecule, change the interaction between molecules, and then affect its physical and chemical properties.
And its chemical properties are greatly affected by reaction conditions. Temperature, solvent, catalyst and other factors can significantly change the reaction rate and product selectivity. Only by properly regulating these conditions can its chemical properties be effectively utilized to achieve the desired chemical synthesis goal.

To prepare 4-alkyne-3-methoxycarbonyl benzyl alcohol, you can follow the following ancient methods.
First, start with halobenzyl, and first react with the alkynylation reagent for nucleophilic substitution. Take an appropriate amount of halobenzyl, dissolve it into a suitable organic solvent, such as dimethylformamide (DMF), add a base such as potassium carbonate, and stir well. Then slowly add the alkynylation reagent, such as alkynyl lithium or alkynyl Grignard reagent, to control the temperature. This process needs to be protected by an inert gas, such as a nitrogen environment, to prevent side reactions from occurring. After the reaction is completed, after post-treatment, such as extraction, washing, drying, and column chromatography separation, benzyl compounds containing alkynyl groups can be obtained.
Second, the alkynyl group in the above product is converted into methoxycarbonyl group by an appropriate method. The product can react with carbon monoxide and methanol in the presence of a catalyst. The commonly used catalyst is a palladium-based catalyst, such as palladium chloride (PdCl ²) combined with a ligand such as triphenylphosphine (PPh 🥰). At a certain temperature and pressure, carbon monoxide and methanol are introduced, and the reaction number is reduced. After the reaction is completed, after separation and purification, the catalyst and the unreacted raw materials are removed, and 4-alkynyl-3-methoxycarbonyl benzyl alcohol can be obtained.
Third, benzyl alcohol derivatives can also be used as starting materials, and alkynyl groups are first introduced, and then methoxycarbonylated. For example, benzyl alcohol compounds containing alkynyl groups are prepared by nucleophilic substitution reaction between benzyl alcohol and halogenated alkynes under alkali catalysis. Then the compound and dimethyl carbonate are carbonylated under the action of basic catalysts to obtain the target product. In this process, the choice of base is quite important, such as sodium hydride (NaH) or potassium tert-butyl alcohol (t-BuOK), and the reaction conditions need to be carefully controlled. Temperature, time, and the proportion of reactants are all related to yield and purity.
All methods have advantages and disadvantages, and the optimal method should be selected according to the actual situation, such as the availability of raw materials, cost, and difficulty of reaction conditions, in order to obtain pure 4-alkyne-3-methoxycarbonylbenzyl alcohol.

4-Hydroxy-3-methoxyacetophenone needs to pay attention to many matters during storage and transportation.
When it is stored, the first environment is dry and cool. This is because if the substance is in a humid environment, it is susceptible to water vapor, or causes changes in properties, or even chemical reactions occur, which reduce its quality. For example, if the humid gas erodes for a long time, or destroys the molecular structure, it will affect the subsequent use effect. And the temperature should not be too high. High temperature may cause increased volatilization of the substance, or cause adverse reactions such as thermal decomposition.
Furthermore, the storage place must be well ventilated. Good ventilation can disperse the gas that may be generated by the volatilization of the substance in time to prevent the accumulation of gas from forming a safety hazard. If the ventilation is not smooth and the volatile gas gathers, in case of open fire or static electricity, there is a risk of fire or even explosion.
At the same time, when storing, it should be stored separately from oxidants, acids, etc. Because of its active chemical nature, contact with oxidants is prone to oxidation reactions, causing combustion or even explosion; coexistence with acids may also cause violent chemical reactions, resulting in dangerous situations.
During transportation, the packaging must be particularly solid and reliable. Only in this way can it ensure that the material does not leak under the common conditions of transportation such as bumps and vibrations. If the packaging is not good, there will be a slight collision during transportation. Once the material leaks, it may not only cause losses, but also cause harm to the environment and surrounding personnel.
And transportation vehicles need to be equipped with corresponding emergency treatment equipment and protective equipment. In the event of an emergency such as a leak, effective measures can be taken in a timely manner to avoid the expansion of harm. For example, prepare adsorption materials to deal with leaked liquids, and protective equipment can ensure the safety of handling personnel.
When transporting, you must also strictly abide by relevant transportation regulations, drive according to the designated route, and avoid densely populated areas and important places. This can reduce the casualties and property losses caused by accidents.
