It can be achieved by temperature regulation to achieve its specific phase state to meet different reaction requirements. The boiling point of is about 285-290 ° C, and the boiling point is quite high, indicating that the substance can boil into a gaseous state at high temperatures, reflecting its strong intermolecular forces, relatively stable structure, and can maintain a liquid or solid state in a higher temperature environment. It is not easy to evaporate and dissipate, which is crucial for reactions or processing processes that need to be carried out at higher temperatures. 1,14-tetraglycol is slightly soluble in water, but soluble in organic solvents such as ethanol and ether. This solubility feature makes it possible to select suitable solvents according to different needs during chemical synthesis or material preparation to dissolve 1,14-tetraglycol, make it participate in various chemical reactions, or prepare a uniform solution system, in order to achieve specific material properties or reaction goals. In addition, 1,14-tetraglycol has certain hygroscopicity and may absorb part of the water in a humid environment. Therefore, it is necessary to pay attention to keep the environment dry during storage to prevent it from affecting quality and performance due to moisture absorption, to ensure that stable physical and chemical properties can be maintained during use, and to provide a reliable material basis for subsequent applications.

Second, in the field of materials science, it can be used to synthesize polymer materials with special properties. Due to its long chain structure, it can improve the flexibility and toughness of polymer materials. When adding polyurethane elastomers, it can optimize the mechanical properties of elastomers, make them more elastic and wear-resistant, and is widely used in automotive interiors, sports shoe soles and other fields that require high material flexibility and durability. Third, in the cosmetic industry, tetradecanediol can be used as a moisturizer and softener. It can form a protective film on the surface of the skin, reduce moisture loss, achieve moisturizing effect, and keep the skin hydrated; and can give cosmetics a delicate texture, improve applicability, and enhance user experience. It is often found in skin care products such as creams and lotions. Fourth, in the fragrance industry, it can be used as a fragrance fixative due to its unique smell and chemical stability. The assistant fragrance better adheres to the surface of the object, prolongs the fragrance retention time, and plays an important role in perfumes, air fresheners and other products to ensure the lasting emission of aroma.

The synthesis of 1% 2C14-tetradecanediol is a key issue in the field of organic synthesis. According to the ancient method, there are many ways to find. First, tetradecanediol can be obtained by a series of complex reactions. First, tetradecanediol is added to a specific reagent to introduce a transformable functional group. For example, it is added to hydrogen bromide to form halogenated hydrocarbon derivatives. Then, through hydrolysis, the halogen atom is converted into a hydroxyl group, and then through appropriate oxidation and reduction steps, 1,14-tetradecanediol can be obtained. Second, tetradecanediol is used as the starting material. First, tetradecanediol is esterified with alcohol under acid catalysis to form tetradecanediol. Then, strong reducing agents, such as lithium aluminum hydride, are used to reduce the ester group and convert it into alcohol hydroxyl groups to obtain the target product 1,14-tetradecanediol. Third, the method of microbial fermentation can also be used. Screening specific microbial strains, using a suitable carbon source as the substrate, under specific culture conditions, the microorganisms can gradually convert the substrate into 1,14-tetradecanediol through their own metabolic pathways. Although this method has the advantages of green environmental protection, it requires quite high screening and culture conditions. There are various methods for synthesizing 1,14-tetradecanediol, each with its own advantages and disadvantages. In practical applications, it is necessary to carefully choose the appropriate synthesis path according to factors such as specific needs, raw material availability and cost.

When storing and transporting 1% 2C14-tetradecyl alcohol diether, many key matters need to be paid attention to. First, storage is essential. This substance should be placed in a cool, dry and well-ventilated place. Because of its high temperature and humid environment, it may cause quality deterioration. Cover high temperature will enhance the molecular activity, or cause chemical reactions, which will damage its chemical stability; moisture is easy to let water vapor mix, affecting purity. And it needs to be placed separately from oxidants, acids and other substances to prevent interaction and danger. Because tetradecyl alcohol diether has specific chemical properties, it may react violently when encountering oxidants or acids, such as combustion, explosion, etc. At the same time, the storage place should be clearly marked to prevent misuse. Second, the care of transportation. It is necessary to ensure that the packaging is intact during transportation. If the packaging is damaged, it is not only easy to cause material leakage, pollute the environment, but also likely to cause accidents due to contact with external substances. The means of transportation also need to be clean and dry to avoid residual impurities from reacting with tetradecyl alcohol diether. And during transportation, high temperature and sun exposure should be avoided to prevent the material from being decomposed or volatilized by heat. In addition, transportation personnel should be familiar with the characteristics of the substance and emergency treatment methods. In case of emergencies, they can respond in time and properly to ensure the safety of transportation.

The effects of 1,14-decanediol on the environment and human health are particularly important to the world. At one end of the environment, this substance may circulate between water bodies, soils and other media. If it is released into natural water bodies, it is difficult to experience significant ecological changes initially or due to small amounts. However, it is delayed, accumulated over time, or has various effects on aquatic organisms. The photosynthesis of aquatic plants may be disturbed by it, resulting in growth retardation and even apoptosis. Aquatic animals may cause physiological disorders due to ingestion of food containing this substance or direct contact through water bodies. If the reproductive system of fish may be damaged, the amount of spawning will decrease, and the survival rate of juvenile fish will also be low. And its accumulation in the soil, or change the soil microbial community structure, affect soil nutrient cycle and fertility. As for the health of the human body, it can enter the human body through breathing, skin contact or dietary intake. If it is exposed to the skin, it may cause skin allergies, erythema, itching and other diseases. Long-term inhalation of aerosols containing this substance may damage the mucosa of the respiratory tract, causing respiratory diseases such as cough and asthma. Especially worrisome, it may accumulate in the body and gradually involve the organs. Studies have shown that it may interfere with the human endocrine system, affect hormone balance, and pose a potential threat to reproductive, immune and other systems. Therefore, the use and emission of 1,14-decanediol should be strictly controlled to reduce its harm to the environment and human health, and to ensure ecological balance and human safety.
