Participates in emulsion polymerization and gives special properties to polymers. Such as improving the stability of polymer emulsions, improving the water resistance of polymers, etc., it is widely used in the preparation of various high-performance emulsion products, such as architectural coatings, adhesives, etc.
In addition, in the field of petroleum exploration, sodium allyl sulfonate can be used as an oilfield chemical. It is used to improve crude oil recovery. By changing the wettability of rock surfaces and reducing the interfacial tension between oil and water, it is easier for crude oil to flow out of rock pores and improve oil extraction efficiency.

The physical and chemical properties of sodium-allyl sulfonate (35% aqueous solution) are as follows:
The appearance of this substance is often colorless to light yellow transparent liquid. The cover is colorless and transparent because it contains a lot of water, and the water is colorless and transparent. Sodium allyl sulfonate dissolves in it, so it appears like this as a whole.
It has good water solubility. Because the molecular structure of sodium allyl sulfonate contains hydrophilic sulfonate groups, it can interact with water molecules in the form of hydrogen bonds, etc., so that it can be well dissolved in water to form a uniform and stable solution.
In terms of chemical stability, it is relatively stable under general conditions. However, allyl has an unsaturated double bond structure. When it encounters specific conditions such as high temperature and strong oxidants, the double bond is prone to react, or cause chemical changes such as polymerization and oxidation.
The pH value of its aqueous solution varies slightly according to the preparation process and impurity conditions, and is roughly in the range of neutral to weakly basic. This is because the structure of sodium allyl sulfonate itself will undergo weak hydrolysis in water, and the sulfonic acid group will unite with hydrogen ions in the water, so that the hydroxide ions in the solution will increase relatively, and then show a weak alkaline tendency.
From the perspective of density, due to the presence of 35% sodium allyl sulfonate and 65% water, its density is related to the density of water and sodium allyl sulfonate itself, and is usually slightly greater than the density of water. The specific value depends on accurate measurement.
In addition, the substance has a certain degree of hygroscopicity. Due to the strong affinity of the sulfonic acid group to water molecules, it is easy to absorb water from the air when the ambient humidity is high, resulting in an increase in its own water content.

When storing sodium-allyl sulfonate (35% aqueous solution), many things need to be paid attention to. This is a chemical substance, its nature is active, and it must be treated with caution in the temperature and humidity of the storage environment. It should be stored in a cool, dry and well-ventilated place. If the temperature is too high, or the reaction may be accelerated, which will damage its quality; if the humidity is too high, it may cause deliquescence and damage its properties.
Furthermore, it must be prevented from contacting with incompatible substances. Sodium allyl sulfonate has specific chemical activity. When it encounters certain oxidizing agents, reducing agents or acid-base substances, it may react violently. If it is light, it will lose its efficacy, and if it is serious, it may cause safety risks, such as fire and explosion. Therefore, the storage place should be isolated from such substances to ensure safety.
At the same time, the choice of storage container is also crucial. Containers made of corrosion-resistant materials are required. The solution of sodium allyl sulfonate may be corrosive to a certain extent. If the container is not resistant or leaks, it will not only pollute the environment, but also cost materials, and there are safety concerns.
In addition, the storage area should be clearly marked, showing the name of the substance, characteristics and precautions, etc., so that the relevant personnel can see at a glance. When taking and handling, they should operate according to the regulations to avoid accidents. And the storage condition should be regularly checked to see if the container is damaged, whether the substance has deteriorated, etc., to ensure that it is always in a safe and stable state.

Preparation of 35% concentration of sodium allyl sulfonate aqueous solution, the process is roughly as follows:
First of all, you need to choose a good raw material, and the quality of allyl alcohol and sodium bisulfite needs to be high to ensure a smooth reaction. Prepare a reaction vessel, preferably a reactor with good material, which needs to be able to withstand temperature, pressure and corrosion. Slowly inject the metered allyl alcohol into the reactor. This step must be careful, control the injection rate, and do not splash the allyl alcohol. Next, add sodium bisulfite at a specific rate, and the addition time should be uniform. The ratio of the two needs to be accurate to achieve the best reaction effect.
In order to promote the rapid progress of the reaction, an appropriate amount of catalyst needs to be added. The choice of catalyst is very critical, and its dosage should also be strictly controlled. If it is too small, the reaction will be delayed, and if it is too much, it may cause side reactions. During the reaction, the regulation of temperature is of paramount importance. It is usually maintained in a certain temperature range, operated by a specific heating procedure, and precisely controlled by a heating device. During this process, pay close attention to temperature changes. If the temperature fluctuates too much, the heating power needs to be adjusted in time.
At the same time, use a stirring device to fully mix the reactants. The stirring rate needs to be moderate. If it is too fast, it is easy to cause local overheating. If it is too slow, it will be unevenly mixed, which will affect the reaction process. As the reaction progresses, the reaction liquid is taken and tested regularly to observe its composition changes. When the test shows that the reaction has reached the expected degree
After the reaction is completed, the product may contain impurities, and the solid impurities need to be removed by filtration or other methods. After that, the filtrate is concentrated or diluted to make the concentration of sodium allyl sulfonate accurate to 35%. The final product needs to be properly stored in a cool, dry and dark place to prevent deterioration. The whole preparation process, all links are closely linked, and any mistake in any link can affect the quality of the product.
