Butylnaphtalenesulfonic acid sodium salt, also known as sodium butylnaphthalene sulfonate, CAS number 25638-17-9. From the appearance, it is a white powder substance, easily soluble in water, belongs to the anionic surfactant. Its molecular formula is C14H15NaO2S and molecular weight is 270.32. It is stable in hard water, salt, acid and weak lye. In some areas with hard water quality for textile printing and dyeing processing, the use of butylnaphtalenesulfonic acid sodium salt as a penetrant or wetting agent, do not worry about the impact of calcium and magnesium ions in hard water, still can ensure good use results.
With its unique properties, butylnaphtalenesulfonic acid sodium salt CAS 25638-17-9 has a wide range of applications in many industrial fields :
Textile printing and dyeing industry
In textile printing and dyeing industry, butylnaphtalenesulfonic acid sodium salt is mainly used as penetrant and wetting agent. In the enzymatic desizing process, it can help the enzyme quickly penetrate into the interior of the fabric fiber, accelerate the decomposition and removal of the slurry, improve the desizing efficiency, make the fabric surface cleaner, and lay a good foundation for the subsequent dyeing, printing and other processes. In the process of wool carbonization, it can reduce the surface tension between the wool fiber and the carbonization liquid, so that the carbonization liquid can quickly and evenly penetrate into the wool fiber, effectively remove impurities such as grass in the wool, and minimize the damage to the wool fiber to ensure the quality and performance of the wool. butylnaphtalenesulfonic acid sodium salt is also indispensable in processes such as folding, chlorination and rayon treatment, which can make the treatment solution better contact with the fiber, ensure the treatment effect is uniform, and improve the quality and appearance of the textile.
Paper and lake industry
In the paper manufacturing process, butylnaphtalenesulfonic acid sodium salt acts as a wetting agent, which can make the fiber surface quickly wetted by water, promote the interweaving and combination between the fibers, and improve the evenness and strength of the paper. In the lake industry, it can help the pigment evenly dispersed in the solution, enhance the affinity between the pigment and the carrier, make the color of the lake more bright and stable, and improve the quality and performance of the lake products. Adding 10% butylnaphtalenesulfonic acid sodium salt solution to the organic pigment is conducive to color paste modulation, which can make the pigment better dispersed in the base material and ensure the stability and uniformity of the color paste.
Rubber industry
In the rubber industry, butylnaphtalenesulfonic acid sodium salt CAS 25638-17-9 is an important emulsifier in the preparation of rubber pulp. In the preparation process of rubber pulp, it can reduce the surface tension between rubber particles and solvent, so that rubber particles are uniformly dispersed in the solvent, forming a stable emulsion system. This stable rubber pulp is convenient for subsequent processing and application, and improves the quality and performance of rubber products.
Other fields
In the pesticide and herbicide industry, butylnaphtalenesulfonic acid sodium salt CAS 25638-17-9 is used as a wetting agent, which can make the active ingredients of pesticides better adhere to the surface of plants or pests, and improve the efficacy of pesticides. In the paint and ink industry, it acts as a dispersant to evenly disperse pigment particles in paint or ink, prevent pigment agglomeration, ensure uniform color and stability of paint and ink, and also help improve the printability and coating performance of products.
Unilong reminds you that although butylnaphtalenesulfonic acid sodium salt has important applications in many industrial fields, it also has certain safety risks and needs our special attention. It is irritating to the eyes, respiratory system and skin. If during the operation, the butylnaphtalenesulfonic acid sodium salt CAS 25638-17-9 accidentally comes into contact with the eyes, it may cause uncomfortable symptoms such as eye pain, redness, tears, and even affect vision. When inhaled dust or vapor containing butylnaphtalenesulfonic acid sodium salt, it can irritate the respiratory system, causing symptoms such as cough, wheezing, and difficulty breathing. Direct skin contact with it may cause allergic reactions such as skin redness, itching, and rashes. Therefore, when using butylnaphtalenesulfonic acid sodium salt, it is necessary to improve safety awareness and strictly comply with the relevant safety operating procedures.
