2-Hydroxy-2-carboxyl-1,3-propanediol (Bropol) is mainly used in a variety of fields. In daily chemicals, it is often used as a preservative. Because of its good antibacterial properties, it can inhibit and kill many microorganisms such as Gram-positive bacteria, Gram-negative bacteria, fungi, yeasts, etc., so it is widely used in cosmetics and personal care products, such as creams, lotions, shampoos, body washes, etc., to effectively prevent products from being contaminated by microorganisms and prolong shelf life. In the coatings industry, it can be used as a preservative for coatings, latex paints, etc., to resist microbial erosion of coatings, avoid mildew, deterioration, odor and other conditions of coatings, and maintain the performance and quality of coatings. In the paper industry, it can prevent pulp from spoiling due to microbial growth during storage and production, ensure pulp quality, and improve paper production efficiency and quality. In the field of water treatment, it can be used for industrial circulating water, sewage treatment, etc., to control the growth of microorganisms in water, prevent microorganisms from causing pipe blockage, corrosion and other problems, and ensure the normal operation of water systems. If "Tiangong Kaiwu" records the function of this object in classical Chinese, or as follows: "2-Hydroxy-2-Carboxyl-1,3-Propylene glycol, commonly known as Bropol. For daily use products, it can resist the disturbance of microorganisms, and store creams, lotions, and things that wash the body to prevent it from spoiling and prolong its shelf life. For coatings, it can protect it from the invasion of microorganisms, avoid the risk of mildew and odor, and protect its quality. When making paper, it can keep the pulp safe, prevent it from being spoiled due to the growth of microorganisms, and improve the quality of the paper. As for water treatment, it can prevent microscopic matter in the water to multiply, and the water protection system can run smoothly, avoiding pipe congestion and rot. "

2-% cyanogen-2-fluoryl-1,3-propanediol (Bropol) is a commonly used preservative, but it has many safety risks and cannot be ignored. First, it is irritating to the skin. Contact with human skin can cause redness, swelling, itching, and tingling. If the skin is already sensitive, the reaction may be more severe, and long-term contact may cause skin diseases such as contact dermatitis. Gu Yun: "The skin is hidden from the body. If it is irritated, it will be endogenous." The irritation of this substance to the skin needs to be prevented. Second, it is harmful to the eyes. Once accidentally into the eyes, it can cause severe eye pain, tears, blurred vision and other symptoms. In severe cases, it may damage the cornea and affect vision. "The eye is the window to the soul", and the eyes are damaged, which is extremely harmful. Therefore, when using products containing this substance, be very careful not to let it into the eyes. Third, it has certain toxicity. Although it is used as a preservative, the amount of use may be limited, but excessive ingestion or inhalation will still endanger health. Oral ingestion may affect the digestive system, causing nausea, vomiting, abdominal pain and other symptoms; inhalation of its dust or volatiles, or irritation of the respiratory tract, causing cough, asthma, etc. "Poison enters the body, such as ant erosion embankment, accumulation of micro-damage." Fourth, environmental risks cannot be ignored. If this substance flows into the environment, it spreads through water, soil, etc., or has toxic effects on aquatic organisms, soil microorganisms, etc., destroying the ecological balance. "Everything in heaven and earth is interdependent, and all things are damaged, and all will prosper." If the environment is damaged, it will eventually affect human beings themselves. From this perspective, although 2% cyanogen-2-fluoryl-1,3-propanediol (Bropol) has anti-corrosion purposes, it has many safety risks. When using it, we should be cautious and weigh the pros and cons to ensure the safety of people and the environment.

In its structure, two methoxy groups are attached to a specific position of the benzene ring, which endows the substance with certain stability and reactivity. From the perspective of physical properties, this compound may be a solid at room temperature. Due to intermolecular forces, it has a certain melting point and boiling point. And because it contains benzene rings, it has a slightly aromatic odor. In terms of chemical properties, the conjugated system of the benzene ring makes the compound electrophilic substitution reactive. Methoxy is the power supply group, which can increase the electron cloud density of the benzene ring and make electrophilic substitution more likely to occur, such as halogenation, nitrification, and sulfonation reactions. For example, when reacted with bromine under appropriate conditions, bromine atoms will preferentially replace the methoxy o and para-hydrogen atoms on the benzene ring. At the same time, because of its methoxy group, it may participate in some reactions involving ether bonds. In case of strong reducing agents, the methoxy group may be reduced to the corresponding phenolic compound. And in the compound molecule, the carbon-oxygen bond at the connection between the benzene ring and the methoxy group can be broken under specific conditions, triggering a series of reactions.
