2-% aminoethanesulfonic acid, that is, taurine, its main uses are as follows:
Taurine plays a key role in many physiological processes of the human body. In terms of dietary supplementation, it is commonly found in various functional beverages. For example, many functional drinks made to refresh the mind today are more taurine, because it can help the human body relieve fatigue. When people are short of energy due to long hours of work, study or long-distance driving, drinking such drinks can boost their spirits and reduce the feeling of fatigue.
In the field of medicine, taurine also plays an important role. It can assist in the treatment of certain cardiovascular diseases. For some people with poor heart function, doctors may recommend supplementation with taurine as appropriate. Gein taurine can regulate myocardial contractility and maintain the normal function of the heart. At the same time, in the central nervous system, taurine is of great significance to brain development and neurostability. In infant milk powder, taurine is often added to help infants and young children develop well in brain and vision. Due to the limited ability of infants and young children to synthesize taurine themselves, external supplementation is particularly critical.
In the field of animal feed, taurine is also widely used. Adding taurine to poultry, livestock and aquaculture feeds can enhance animal immunity and promote their growth and development. For example, in aquaculture, the addition of appropriate taurine can enhance the disease resistance of aquatic organisms such as fish and shrimp, reduce the occurrence of diseases, and improve breeding benefits.
In summary, 2-aminoethanesulfonic acid, or taurine, plays an important role in many industries such as food, medicine, and feed, and has a significant impact on human health and animal breeding.

2-% hydroxypropionitrile is an organic compound with relatively stable chemical properties.
This substance contains two functional groups of hydroxyl (-OH) and cyanyl (-CN). Hydroxyl groups have certain reactivity and can participate in many chemical reactions. For example, under suitable conditions, esterification can occur, and dehydration and condensation with carboxylic acids can form ester compounds. This reaction requires acid as a catalyst and heating. And because there are hydrogen atoms in the adjacent position of the carbon atom connected to the hydroxyl group, it can also undergo elimination reaction. When dehydrating agents such as concentrated sulfuric acid are used and heated, the hydroxyl group and the adjacent hydrogen atom remove a molecule of water to form a carbon-carbon double bond.
Cyanyl groups also have unique properties. Under acidic or alkaline conditions, cyanide groups can undergo hydrolysis reactions. In acidic hydrolysis, amides are formed, which are then hydrolyzed into carboxylic acids and ammonium salts; in alkaline hydrolysis, carboxylic salts and ammonia are formed. At the same time, cyanyl groups can also undergo reduction reactions. Under the action of specific reducing agents, cyanyl groups can be reduced to amino groups (-NH2O) and converted into corresponding amine compounds.
However, on the whole, 2% hydroxypropionitrile is chemically stable at room temperature and pressure without specific reagents and conditions, and the molecular structure remains relatively stable. However, under specific conditions such as strong acids, strong bases, strong oxidants or high temperatures, the above-mentioned chemical reactions will be triggered by the characteristics of functional groups, showing active reactivity.

2-% hydroxypropionitrile is an important intermediate in organic synthesis, and its synthesis methods are rich and diverse. The following are common methods:
1. ** Hydrocyanic acid method **: Using formaldehyde and hydrocyanic acid as raw materials, under the action of a basic catalyst, the two undergo an addition reaction to generate 2-hydroxypropionitrile. The chemical equation of this reaction is: $HCHO + HCN\ stackrel {base} {\ longrightarrow} HOCH_2CN $. The advantage of this method is that the raw materials are easily available and the reaction conditions are relatively mild. However, the disadvantage is that hydrocyanic acid is highly toxic, which requires strict production equipment and operation, and the safety risk is quite high.
2. ** Cyanohydrin method **: Acetaldehyde and hydrocyanic acid are cyanohydrated to produce 2-hydroxypropionitrile. The chemical reaction formula is: $CH_3CHO + HCN\ longrightarrow CH_3CH (OH) CN $. The key to this method is to select an efficient catalyst to improve the reaction rate and yield. This process also requires proper treatment of highly toxic hydrocyanic acid, and fine control of the reaction conditions.
3. ** Hydrolysis of acrylonitrile **: Acrylonitrile is hydrolyzed to form acrylamide first, and then converted into 2-hydroxypropionitrile through further reaction. The specific steps are that acrylonitrile is hydrolyzed into acrylamide sulfate under the action of a catalyst such as sulfuric acid, and then neutralized by ammonia to obtain acrylamide. After that, acrylamide is converted into 2-hydroxypropionitrile through special reaction conditions and catalysts. Although this method is relatively stable in raw materials, there are many reaction steps, complex processes, and high production costs.
4. ** Biosynthetic method **: With the help of microorganisms or enzymes, 2-hydroxypropionitrile is synthesized with suitable substrates. For example, some microorganisms can use specific carbon and nitrogen sources to generate 2-hydroxypropionitrile through complex metabolic pathways in the body. The method has the advantages of mild reaction conditions and environmental friendliness, but it is currently facing challenges such as difficult screening and cultivation of biocatalysts and low production efficiency. Further research is needed to enhance the feasibility of its industrial application.

2-% hydroxypropionitrile requires careful attention during storage and transportation.
When storing, choose the first environment. It must be placed in a cool and ventilated warehouse, away from fire and heat sources. This is a necessary measure to prevent the occurrence of danger due to temperature, open flame and other factors. Because of its certain chemical activity, high temperature or open flame can easily cause accidents. The relative humidity of the warehouse should be controlled in an appropriate range. If the humidity is too high or too low, it may affect its chemical properties and endanger storage safety.
Furthermore, it should be stored separately from oxidants, acids, bases, etc., and must not be mixed. The chemical properties of 2-% hydroxypropionitrile determine that it is prone to chemical reactions in contact with the above substances, or cause serious consequences such as combustion and explosion. At the same time, the warehouse needs to be equipped with suitable materials to contain the leakage, so as to prevent the accidental leakage from being properly handled in a timely manner and avoid the spread of greater hazards.
When transporting, ensure that the container is well sealed to prevent its leakage and volatilization. Transportation vehicles should be equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment to prepare for possible emergencies during transportation. During transportation, the choice of driving routes should also be considered, and sensitive areas such as densely populated areas and important transportation hubs should be avoided to reduce the threat to the public and important facilities in the event of an accident. And when transporting, it is necessary to follow the specified route, do not stop in residential areas and densely populated areas, and strictly follow the established transportation norms to ensure the safety of the entire transportation process.
