5-ethylhexanol, often used as an intermediate in organic synthesis. Its physical properties are as follows:
In appearance, it is usually a colorless and transparent liquid. In terms of odor, it has a mild special odor.
The boiling point is between 184-186 ° C, at this temperature, 5-ethylhexanol changes from liquid to gaseous. The melting point is about -70 ° C. When the temperature is lower than this value, it will solidify into a solid state. The density of
is about 0.834g/cm ³, which means that under the same volume, 5-ethylhexanol is lighter than water (the density of water is 1g/cm ³).
In terms of solubility, it is slightly soluble in water, but it can be miscible with organic solvents such as alcohols and ethers. This is due to its molecular structure having both hydrophobic alkyl moieties and relatively hydrophilic hydroxyl moieties, but the overall hydrophobic effect is stronger, so its solubility in water is limited. Its flash point is 71 ° C, indicating that when the ambient temperature reaches this value, the mixed gas formed by the vapor volatilized by 5-ethylhexanol and air can be ignited when encountering an ignition source. < Br >
This is a common physical property of 5-ethylhexanol, which is of great significance in the fields of chemical production and organic synthesis.

To prepare 2 - (4 - acetoxybenzyl) - 1,3 - dialkane - 5 - acetaldehyde, there are many synthesis methods, which are described in detail below.
First, it can be achieved through a multi-step reaction from a starting material. First, take an appropriate aromatic hydrocarbon, use a specific acylating agent, and under suitable reaction conditions, such as a specific temperature and catalyst, perform acylation reaction to obtain an aromatic hydrocarbon derivative containing an acetoxy group. Afterwards, the derivative is acetalized with an alcohol with a specific structure under acid catalysis and other conditions, and then the structure of dialkane is constructed. After a specific oxidation step, such as selecting a suitable oxidizing agent, in a controlled reaction environment, the specific group is oxidized to an aldehyde group to obtain the target product.
Second, there is also a method of starting with compounds containing similar structures. Starting with compounds with benzyl groups and related protective groups, the protective groups are selectively removed to expose the activity check point. After that, the acetoxy group is introduced into the reaction, and the acetylation reagent can be used to complete this step under suitable conditions. Next, a dialkane ring is constructed through a cyclization reaction, which requires fine regulation of the reaction parameters. Finally, through a specific functional group conversion reaction, the specific group is converted into an aldehyde group to achieve the synthesis of the target product.
Third, there are methods guided by the concept of green synthesis. Using environmentally friendly solvents and catalysts, by optimizing the reaction path, reducing the reaction steps and improving the utilization rate of atoms. For example, using enzyme catalysis or biomimetic catalysis to simulate the synthesis process in vivo, under relatively mild reaction conditions, the synthesis of 2 - (4-acetoxybenzyl) -1,3-dialkane-5-acetaldehyde can not only reduce the impact on the environment, but also improve the selectivity and yield of the reaction.
All these methods of synthesis have their own advantages and disadvantages. In practical applications, appropriate methods should be carefully selected according to factors such as specific needs, availability of raw materials, and cost considerations, in order to achieve the purpose of efficient and green synthesis of target products.

During the storage and transportation of 5-ethylheptane, many key matters need to be paid attention to. This substance is an organic compound and is flammable. Therefore, when storing, it must be placed in a cool and well-ventilated place, away from fire and heat sources to prevent fire. Clear warning signs should be set up in the storage area, and fireworks are strictly prohibited.
Its storage container is also crucial, and a container with good sealing performance must be selected to prevent leakage. Before use, the integrity of the container should be fully checked to see if there are any signs of damage or leakage. When transporting, it should be properly packaged in accordance with relevant regulations to ensure the stability of the transportation process.
In addition, 5-ethylheptane is potentially harmful to human health and may irritate the eyes, respiratory tract and skin. Storage and transportation personnel need to take protective measures, such as wearing protective glasses, gloves and gas masks, to avoid direct contact. In the event of a leak, personnel on site should be quickly evacuated to a safe area, cut off the fire source, and take effective plugging and cleaning measures in a timely manner to prevent the spread of pollution. In short, when storing and transporting 5-ethylheptane, it is necessary to strictly follow safety regulations, and attach great importance to fire prevention, leakage prevention and personal protection to ensure the safety of personnel and the environment.
