What is the main use of sodium dodecanesulfonate?
Sodium dodecanesulfonate (Sodium Dodecanesulfonate), which has a wide range of uses. In the industrial field, it is often used as an ingredient in detergents. Because of its good surface activity, it can reduce the surface tension of water, make oil stains more easily dispersed in water, and has strong decontamination power, so it is commonly found in various cleaning agents to make utensils clean.
In the textile industry, it also has its uses. It can be used as a textile auxiliary to help dyes disperse evenly, making fabrics more uniform in dyeing, bright and lasting in color, and improving the quality of textiles.
In the leather industry, it can act as a leather degreasing agent. It can effectively remove oil from leather, making leather soft and breathable, and at the same time help subsequent processing, such as tanning, dyeing and other processes to proceed smoothly.
In the paper industry, as an auxiliary agent for paper sizing, it can enhance the water resistance of paper, so that the paper can maintain stable performance in humid environments, not easily deformed or damaged, and improve the quality and durability of paper.
In the field of scientific research, it is used as a surfactant in some experiments to assist in dispersing or dissolving specific substances to achieve experimental conditions and purposes, and to help the smooth progress of scientific research. From this perspective, sodium dodecyl sulfonate plays an important role in many industries and has a profound impact on production and life.
What are the physical properties of sodium dodecanesulfonate?
Sodium dodecanesulfonate is one of the organic compounds and is often used as a surfactant. Its physical properties are quite varied.
Looking at its properties, at room temperature, it is mostly white or light yellow crystalline powder, like fine sand, delicate to the touch. Its smell is quite weak and almost odorless, which is particularly advantageous in many application scenarios, without introducing undesirable odor interference.
When it comes to solubility, sodium dodecanesulfonate exhibits good solubility in water. It is easily soluble in water and forms a uniform solution, which makes it able to fully play a role in many aqueous systems. And its aqueous solution is often relatively stable, and it is not easy to precipitate or stratify.
As for the melting point, it is between 170 and 180 ° C. This melting point condition allows it to maintain a stable solid state under normal ambient temperature, and then under appropriate heating conditions, phase changes can occur.
Its density is about 1.09 g/cm ³, which is moderate compared with common liquid or solid substances. In actual operation and application, it is easy to control and measure.
In addition, sodium dodecyl sulfonate has a certain degree of hygroscopicity. In a more humid environment, it easily absorbs moisture in the air, causing its own shape or properties to change slightly. Therefore, during storage and use, it is necessary to pay attention to the humidity conditions of the environment to prevent it from affecting the use effect due to moisture absorption.
What should be paid attention to when storing sodium dodecanesulfonate?
Sodium dodecanesulfonate is a commonly used chemical reagent, and many things should be paid attention to when storing.
First, it must be placed in a dry place. Because the substance is hygroscopic, if the environment is humid, it is easy to cause it to absorb water, or affect its chemical properties and purity, which is unfavorable for subsequent experiments or use. For example, in humid places in the south, if stored improperly, the reagent is easy to agglomerate and difficult to accurately weigh and use.
Second, it should be stored in a cool place to avoid high temperature and open flames. Sodium dodecanesulfonate may be at risk of combustion or explosion in case of hot topics or open flames. When it is hot in summer, if it is stored in a warehouse with too high temperature and close to the fire source, it is easy to cause safety accidents.
Third, it should be stored separately from oxidants, acids, etc. Because of its active chemical nature, contact with these substances or violent chemical reactions may cause danger. If it coexists with strong oxidants, it may cause uncontrollable oxidation reactions.
Fourth, the storage container must be well sealed. To prevent it from being in contact with air for a long time, oxidation or other chemical reactions may occur, causing it to deteriorate. Choosing a suitable sealed container can effectively ensure its quality and stability. In this way, proper storage of sodium dodecyl sulfonate can ensure its stability, play its due role in use, and ensure safe operation.
What are the safety precautions during the use of sodium dodecanesulfonate?
Sodium Dodecanesulfonate (Sodium Dodecanesulfonate) has many safety precautions during use, so let me explain in detail.
This substance is irritating to a certain extent, and contact with the skin can cause discomfort and allergies. Therefore, when using, be sure to wear protective clothing, gloves and goggles for comprehensive protection to avoid direct contact between the skin and the eyes. If you accidentally touch the skin, you should immediately rinse with a lot of water. If you feel uncomfortable, seek medical treatment as soon as possible.
Sodium Dodecanesulfonate in the air or form explosive dust, in case of open flames and hot topics, it is easy to cause combustion and explosion. Therefore, the use environment should be well ventilated, away from fire and heat sources, and smoking is strictly prohibited. Explosion-proof electrical equipment and ventilation systems should be used in the operation site to prevent static electricity accumulation and sparks.
It is highly toxic to aquatic organisms or causes long-term harmful effects. During use, waste and wastewater containing this substance must not be dumped at will to avoid polluting the water environment. Waste should be properly disposed of in accordance with relevant environmental regulations to ensure that it does not cause harm to the ecological environment.
Furthermore, sodium dodecyl sulfonate is corrosive and can corrode certain metals and building materials. When storing and using, avoid contact with easily corroded materials, choose suitable storage containers and equipment, and check regularly to prevent leakage.
When using sodium dodecyl sulfonate, it is necessary to strictly follow the safety operating procedures and always pay attention to all safety matters, so as to ensure that personnel safety and the environment are not damaged.
What is the approximate market price range of sodium dodecanesulfonate?
Sodium dodecanesulfonate often varies in market value due to differences in product price, price, supplier, and quantity. Generally speaking, if it is commonly used in the processing room, small quantities (such as 500 grams) may range from 10 yuan to 100 yuan. If it is a large amount of labor, the price may be reduced to 10 yuan per kilogram.
If it is self-normalized, supplier analysis, etc., the price of a 500-gram package may be between 50 yuan and 150 yuan. If a large number of industrial products are sold to chemical raw materials, the price per kilogram may be as low as 30 yuan to 80 yuan. However, this is a rough estimate, and the price still needs to be determined by the supplier. The market has fluctuations, and the price of different products also has high and low, so the price is uniform.
