The physical properties of (di + -mercury-1,3-diene-5- (trienomethyl) naphthalene are as follows:
Mercury, which is liquid at room temperature and pressure, is the only liquid metal. The color is silvery white and has a metallic luster. The density is relatively high, about 13.59 grams/cubic centimeter, which makes it heavier than many common substances. Mercury has good fluidity and is easy to flow like mercury. Its melting point is extremely low, -38.87 ° C, and its boiling point is 356.6 ° C. In addition, mercury also has a certain volatility, which will slowly evaporate into mercury vapor in the air. This mercury vapor is toxic and harmful to human health.
For 1,3-diene-5- (trienomethyl) naphthalene, as an organic compound, its molecular structure endows it with specific physical properties. Usually, it is mostly in solid form and has certain crystalline properties. The melting and boiling point varies depending on the force between molecules. Generally, the melting point is relatively high, and a certain temperature is required to transform it from solid to liquid. In terms of solubility, it is difficult to dissolve in water, because water is a polar solvent, while 1,3-diene-5- (trienomethyl) naphthalene is a non-polar or weakly polar organic substance, following the principle of "similar miscibility". However, it is soluble in some organic solvents, such as benzene, toluene and other non-polar or weakly polar organic solvents, and can be well miscible with these solvents and dispersed in molecular form. In appearance, it may be white to light yellow crystals. When pure, the crystals are relatively regular, and there may be a certain luster under light irradiation.)

(The following answer is in the style of ancient classical Chinese)
Fu 2 + -hydroxyl-1,3-diene-5- (trienomethyl) naphthalene, its chemical properties are quite unique.
This substance has an unsaturated ethylene bond, so it has an additive property. The ethylene bond can be added to electrophilic reagents such as halogens and hydrogen halides. In case of bromine water, the diatoms of bromine can be added to the carbon sites at both ends of the ethylene bond respectively, causing the bromine water to fade. This is its remarkable characteristic reaction and is quite useful for identification.
Furthermore, because it contains hydroxyl groups, it has certain nucleophilic properties. The hydrogen of the hydroxyl group can be replaced by active metals. If it encounters sodium metal, hydrogen can escape, just like the commonality of alcohols. At the same time, the hydroxyl group can also participate in the esterification reaction, and the carboxylic acid is dehydrated to form an ester under the condition of acid catalysis. This process is like the wonderful combination of alcohol and acid, resulting in the formation of esters with special flavors.
And its naphthalene ring structure also endows it with special chemical activity. Naphthalene rings can undergo substitution reactions, such as nitrification reactions, sulfonation reactions, etc. Under appropriate conditions, nitro and sulfonic acid groups can replace the hydrogen atoms on the naphthalene ring, resulting in the derivation of many useful derivatives.
In addition, due to the existence of a conjugated system in its structure, the delocalization of electrons gives it a certain stability, which also affects its reactivity and selectivity. The conjugated system makes the electron cloud distribution of molecules more uniform, and in chemical reactions, some special reaction paths tend to occur, which are quite different from ordinary non-conjugated system substances.
In summary, 2 + -hydroxyl-1,3-diene-5- (trienyl methyl) naphthalene shows rich and diverse chemical properties such as addition, substitution, and reaction with active metals due to its unique structure. In the field of organic chemistry, it is like a shining star, which contains many values that can be explored and utilized.

To prepare 2-hydroxy-1,3-dialdehyde-5- (trihydroxymethyl) benzyl, the method is as follows:
can be started from the corresponding phenolic compound. For example, using p-hydroxybenzaldehyde as the starting material, it is first protected, and the phenolic hydroxyl group is protected with a suitable protective group such as benzyl group to avoid unnecessary participation of the phenolic hydroxyl group in the subsequent reaction. After
, it is modified by the related reaction of the aldehyde group. The aldehyde group can be used to undergo condensation reaction with certain reagents to introduce the desired functional group. If the hydroxyaldehyde condensation reaction occurs with formaldehyde under basic conditions, groups such as hydroxymethyl group can be gradually introduced. In this process, it is necessary to precisely control the reaction conditions, such as temperature, amount and type of alkali, etc. Too high or too low temperature, and improper alkali content may cause the reaction to proceed in an unfavorable direction and generate by-products.
Then, the protective group is removed at an appropriate stage to re-expose the phenolic hydroxyl group. This step also requires strict control of the reaction conditions, selection of appropriate deprotection reagents and reaction environment, in order to prevent damage to other formed functional groups in the molecule.
Other aromatic compounds with suitable substituents can also be considered as starting materials, and the structure of the target molecule can be gradually constructed through a series of electrophilic substitution, oxidation reduction and other reactions. For example, a suitable substituent is introduced into the aromatic ring first, and then the corresponding group is converted into an aldehyde group through an oxidation reaction. At the same time, attention is paid to the selectivity of the reaction and the coherence and compatibility between the various steps of the reaction, so as to avoid the generation of difficult-to-separate by-products or the failure of the reaction to proceed smoothly to the target product. In this way, after carefully designing and manipulating the reaction in multiple steps, 2-hydroxy-1,3-dialdehyde-5- (trihydroxymethyl) benzyl can be obtained.

Safety is especially important when it comes to safety. Emergency management and management of fire-fighting equipment that is not properly equipped. It is necessary to train people and be familiar with the dangerous characteristics and emergency disposal methods of (trialkyl methyl) benzene. On the way, do not approach dangerous places such as densely populated areas and fire sources, and the speed should be appropriate to avoid strong shocks and collisions, so as to prevent material leakage caused by container rupture.
Unloading, operation must be careful. To unload, do not be rough, to prevent the container from breaking. At the same time, workers should take precautions, such as gas masks, protective clothing, etc., to ensure their own safety.
Therefore, whether it is hidden or (trialkyl methyl) benzene, it is necessary to keep the phase, and pay attention to each other in order to ensure safety.
