1,3-Propanediol

1,3-Butanediol is an organic compound. Although its specific application is not detailed in ancient books such as Tiangong Kaiwu, it must have various uses based on today's chemical knowledge and past chemical practice. First, 1,3-butanediol has good moisturizing properties. In the field of beauty and skin care in ancient times, although there was no precise chemical synthesis of this product, the ancients often looked for natural products with moisturizing effect to moisturize the skin. If 1,3-butanediol was known at that time, it must be used with skin cream. For example, ancient women used flower dew and oil to mix skin care. If 1,3-butanediol is added, it may increase the moisturizing durability and make the skin more moisturized and delicate. Second, because it has a certain solubility and stability, it can be used as a solvent. It may be useful in the pharmaceutical and fragrance-making industries of ancient times. In pharmaceuticals, it can be used to dissolve insoluble drug ingredients to help the drug disperse evenly and improve the efficacy. When making incense, it can dissolve the fragrance, making the aroma more easily distributed and lasting, and preparing a more pleasant fragrance. Third, 1,3-butanediol can participate in some chemical reactions, or can be used to prepare special materials. In the process of metal casting, ceramic firing and other processes, ancient craftsmen often searched for special additives to improve the properties of materials. If there is 1,3-butanediol, it can be used as an additive in a specific process to optimize the texture and strength of the material, such as adding it to the ceramic glaze, or it can make the glaze smoother, more vivid and lasting.

1,3-Butanediol is an important organic compound. Although there were no modern production methods as rich and diverse as in ancient times, the ancients also had unique methods. One of them can be obtained from natural plant fermentation. In the past, it was known that many plants were rich in carbohydrates. After being fermented by specific microorganisms, the microorganisms would convert the carbohydrates in the plants into various metabolites, which may contain 1,3-butanediol. For example, choose grains and fruits with high sugar content, wash and cook them, and then insert suitable fermentation strains to ferment under appropriate temperature, humidity and other conditions. During the fermentation process, the microbial enzyme system will play a role, gradually catalyzing the conversion of substrates, or can generate 1,3-butanediol. Although the yield of this method may not be high, it is relatively easy to obtain raw materials, and the process operation is feasible under the conditions of the time. Second, some plants themselves can also synthesize 1,3-butanediol. The ancients would explore specific plants and obtain them through collection, refining and other processes. Through long-term observation and practice, they knew that some plants contained such substances. After collection, simple refining methods such as water extraction and distillation may be used. Water extraction involves cutting up plants and soaking them in water, so that 1,3-butanediol and other ingredients are dissolved in water, and then separated by further treatment; distillation uses the difference in boiling points between 1,3-butanediol and other ingredients to heat the mixture, so that 1,3-butanediol is vaporized and condensed. Third, in ancient chemical practices such as alchemy, 1,3-butanediol may also be accidentally generated. When alchemists try to mix various minerals and plants to refine medicinal pills, although the goal is not to produce 1,3-butanediol, this substance is generated under complex chemical reaction systems or due to the interaction of certain components in the raw materials. The alchemy process involves heating, mixing and other operations to create conditions for chemical reactions, or occasionally 1,3-butanediol is formed. Alchemists have observed, recorded, or also know that some combinations and conditions of this substance can be generated.

1,3-butadiene is an important organic chemical raw material, and its market prospects are as follows: In today's world, technology is new and industry is prosperous. 1,3-butadiene plays an indispensable role in many fields. Looking at the field of synthetic rubber, this is the key raw material for the production of cis-butadiene rubber, styrene-butadiene rubber, nitrile rubber, etc. With the vigorous rise of the automotive industry, the demand for tires is like water in a river. Tires need to have excellent properties such as wear resistance and aging resistance, and synthetic rubber made of 1,3-butadiene can just meet these requirements, so the rise of the automotive industry has opened up a broad market for 1,3-butadiene. And rubber products are also widely used in construction, machinery, aerospace and other industries, and the demand continues to grow. Furthermore, in the field of synthetic resins and plastics, 1,3-butadiene can participate in the synthesis of ABS resins. ABS resins have good comprehensive properties, such as high strength, high toughness, easy processing, etc., and are widely used in electronic and electrical shells, automotive interior parts, etc. With the development of electronic appliances and automotive industries, the demand for ABS resins is on the rise, which also drives the growth of the 1,3-butadiene market. However, the 1,3-butadiene market also faces some challenges. The production process has high energy consumption and has a certain impact on the environment. With the tightening of environmental protection regulations, enterprises need to invest more funds in environmental protection and improve production processes, which may increase production costs. And the market competition is fierce, and many enterprises are involved in production, resulting in the risk of overcapacity. However, with the development of emerging industries such as new energy vehicles and high-end equipment manufacturing, the demand for high-performance materials is on the rise. Due to its excellent performance, 1,3-butadiene will still occupy an important place in the market, and the prospects are still promising. It is expected to further develop in technological innovation and market expansion.

1,3-Butanediol has several properties. First, it is mild in nature and does not irritate the skin. It is often used in many skin care products. It can moisturize the skin, keep the skin hydrated and smooth, just like spring rain moisturizing, nourishing the skin. Furthermore, this substance has a good moisturizing effect. Its molecular structure can capture and retain moisture, just like a sponge absorbs water, which can keep the skin hydrated and prevent the loss of moisture from the skin. Even in a dry environment, it can maintain the skin's hydration. Also, the chemical properties of 1,3-butanediol are quite stable, which can help maintain the stability of the system in the product, make the properties of the product not easy to change, and prolong its use period, just like setting the needle of the sea, stabilizing the quality of the product. And its solubility is quite good, it can be soluble with a variety of substances, which is convenient for formulators to prepare different types of products. It can skillfully integrate various functional ingredients, making the product more rich and diverse, such as craftsmen matching various materials to create exquisite things. In addition, 1,3-butanediol has a certain bacteriostatic effect, which can inhibit the growth of some microorganisms, help to maintain the hygiene and cleanliness of the product, and prevent the deterioration of the product. It is like a guard to protect the product.

1% 2C3-propylene glycol is a commonly used chemical raw material, and there are many points to be paid attention to during use. First, it is related to safety. Although 1% 2C3-propylene glycol is relatively mild, it should not be neglected. It is irritating to a certain extent. If it touches the skin inadvertently, it should be rinsed with a lot of water immediately. If it touches the eyes, it is even more necessary to be cautious. Immediately open the eyelids, rinse with flowing water or normal saline, and seek medical attention if necessary. Use it in large quantities in poorly ventilated spaces, or inhale its volatile aerosol, or cause respiratory discomfort. Therefore, the place of use must be well ventilated. If symptoms such as cough and asthma occur, leave the scene quickly, breathe fresh air, and seek medical attention in severe cases. Second, pay attention to storage conditions. It should be stored in a cool, dry and well ventilated place, away from fire and heat sources to prevent it from evaporating or causing danger due to excessive temperature. Because of its flammability, it is flammable in case of open flames and hot topics, so fireworks are strictly prohibited in the storage area, and they should be stored separately from oxidants. Do not mix storage to prevent chemical reactions. Third, pay attention to the scope of application and dosage. 1% 2C3 -propylene glycol is widely used in food, cosmetics and other fields. It is used in food as a moisturizer, solvent, etc., but the dosage must strictly follow the relevant standards. Excessive use may affect food quality and even endanger human health. It is often used as a solvent and moisturizer in cosmetics to help other ingredients dissolve and improve the moisturizing performance of the product. However, different skin types have different tolerances to it, and those with sensitive skin may cause allergic reactions. Before using cosmetics containing this ingredient, it is recommended to do a local skin test.
