What are the physicochemical properties of 3- (2-Propynyloxy) -1-Propanesulfonic Acid, Sodium Salt
Sodium 3- (2-propanyloxy) -1 -propanesulfonate is an important compound in the field of organic synthesis. It has unique physical and chemical properties, and the understanding of its properties is of key significance in many fields such as chemical and materials.
Looking at its physical properties, under normal circumstances, this compound is mostly white crystalline powder, with fine and uniform particles, dry texture, and no special odor. Its solubility is quite good, and it can be quickly dissolved in water to form a clear and transparent solution. This property makes it easy to participate in various reactions in aqueous systems, or as an additive to disperse evenly in the system. And because of its good solubility, it can maintain a stable physical state as long as it avoids moisture during transportation and storage.
As for the chemical properties, the presence of the propiynyloxy group in the compound gives it unsaturation, allowing it to participate in addition reactions. In case of electrophilic reagents, the three bonds of the propiynyl group can be added to generate various derivatives, expanding a broad path for organic synthesis. At the same time, the sulfonic acid group makes the compound acidic to a certain extent. Under appropriate conditions, it can neutralize with bases to generate corresponding salts. This chemical property plays a key role in regulating the pH of the reaction system and preparing specific functional materials. Its stability cannot be ignored. Under normal conditions, the chemical properties of the compound are relatively stable. However, under extreme conditions such as high temperature and strong oxidants, reactions such as decomposition or oxidation may occur. Therefore, environmental conditions need to be properly controlled during storage and use.
3- (2-Propynyloxy) -1-Propanesulfonic Acid, Sodium Salt What are the precautions when storing
3 - (2 -proparyloxy) -1 -propanesulfonate sodium salt, when storing, pay attention to many things.
First, this substance is quite sensitive to the temperature and humidity of the environment. High temperature will easily cause its chemical properties to change, or cause decomposition reactions, which will damage its quality. Therefore, it should be stored in a cool place, so that the temperature is constant in a suitable range, not too high. Humidity should also be controlled. If the humidity is too high, it is easy to make it damp, or cause agglomeration, which will affect its use. It must be stored in a dry place.
Second, the compatibility of this substance with other substances should also be paid attention to. Do not co-store with highly oxidizing or reducing substances to prevent violent chemical reactions and cause danger. In case of strong oxidizing agents, there may be a risk of combustion or explosion; in case of strong reducing agents, it may also cause its structure to change and lose its original properties.
Third, the storage place should be well ventilated. If the ventilation is not smooth, the volatile gases or accumulation will not only damage the environment, but also be detrimental to human health. Strengths in this environment may cause respiratory tract and other discomfort.
Fourth, the packaging must be tight. To prevent external factors from interfering and causing it to come into contact with air, water vapor, etc. Damaged packaging can easily deteriorate, so it is necessary to always check the integrity of the packaging. If there is any damage, deal with it quickly.
Only in this way can the sodium salt of 3- (2-propionyloxy) -1 -propanesulfonate be stored to maintain its quality for subsequent use.
What is the synthesis method of 3- (2-Propynyloxy) -1-Propanesulfonic Acid, Sodium Salt?
To prepare sodium 3- (2-propanyloxy) -1-propanesulfonate, the following method can be used:
Propanesulfonolactone and 1,3-propanesulfonactone are selected as starting materials. Both are readily available chemical raw materials.
First, propanesulfonactone is placed in the reaction vessel and diluted with an appropriate amount of organic solvent, such as dichloromethane, N, N-dimethylformamide, etc. The function of the organic solvent is to mix the reaction materials evenly and promote the smooth progress of the reaction.
Then, under the condition of stirring and cooling, slowly add 1,3-propanesulfonactone dropwise to the solution containing propanesulfonactone. The purpose of cooling is to prevent the reaction from being too violent and causing side reactions to occur. This reaction is a nucleophilic substitution reaction. The hydroxyl oxygen of propargyl alcohol is nucleophilic and will attack the carbon atom of 1,3-propane sulfonolactone and open the sulfonolactone ring.
During the reaction process, thin layer chromatography (TLC) can be used to monitor. When the raw material point disappears, the reaction is nearly complete.
After the reaction is completed, the organic solvent is removed first. If dichloromethane is used as the solvent, the solvent can be volatilized under reduced pressure by a rotary evaporator.
Next, the obtained crude product is purified. The purification method can be column chromatography. Using silica gel as the fixed phase, and a suitable proportion of ethyl acetate and petroleum ether mixture as the mobile phase, the crude product is separated by loading. Separation can be achieved due to the different distribution coefficients of the product and impurities in the stationary and mobile phases.
Another purification method is recrystallization. Depending on the solubility of the product in different solvents, choose the appropriate solvent. Heat to dissolve the crude product, filter out insoluble impurities while hot, and then cool the crystallization to obtain pure 3- (2-proparynyloxy) -1-propanesulfonate sodium crystals.
In addition, attention should be paid to safety during the reaction. Proparynyl alcohol is irritating and flammable, 1,3-propanesulfonide is toxic and corrosive, and the operation is carried out in a fume hood, wearing protective clothing, gloves and goggles to ensure the safety of the experimenter.

Sodium 3- (2-proparyloxy) -1 -propanesulfonate, this compound is widely used in the field of electroplating.
In the art of electroplating, additives are essential to obtain a good coating. Sodium 3- (2-proparyloxy) -1 -propanesulfonate is often used as an additive for nickel plating, which can effectively improve the characteristics of the coating in the nickel plating solution. This agent can make the nickel coating more detailed and uniform, and improve the brightness and flatness of the coating. In Watt nickel plating solution, an appropriate amount of this compound is added to increase the cathodic polarization, thereby optimizing the crystallization process, making the microstructure of the nickel layer more dense, and greatly enhancing the protective performance of the coating.
This compound is also indispensable in the nickel plating process of printed circuit boards (PCBs). The plating of PCBs requires precise control of the thickness and quality of the coating. Sodium 3- (2-propionyloxy) -1-propanesulfonate can help to achieve this purpose. It can make nickel deposit evenly on the surface of the circuit board, ensure that the thickness of the coating in all parts is consistent, avoid local overthickness or overthinness, and ensure the stability of the electrical performance of the circuit board.
In addition, in some special electroplating requirements scenarios, such as functional electroplating, when the coating is to be given specific physical or chemical properties, 3- (2-propionyloxy) -1 -propanesulfonate and other additives work synergistically to meet diverse functional requirements, such as enhancing the wear resistance and corrosion resistance of the coating. Therefore, its application in the electroplating industry is of great significance for improving the quality of the coating and expanding the scope of application of the electroplating process.
