Linear Alkyl Benzene Sulphonic Acid Usage and Synthesis :

Linear Alkyl Benzene Sulphonic Acid is an important surfactant, also known as sodium dodecyl benzene sulfonate,  a Honey Brown Liquid. LABSA Raw Materials is an anionic surfactant with good surface activity and emulsification  properties, LABSA CAS 27176-87-0 Widely used in detergents, cleaning agents, dyes, coatings, cosmetics,  paper and other fields.

The molecular formula of sodium alkyl benzene sulfonate is C18H29NaO3S and the molecular weight is 348.48. In its chemical structure, alkyl chain is connected to benzene ring and sulfonic acid group is connected to benzene ring. The length and branching of alkyl chain will affect its surface activity and emulsification performance. In general, the alkyl chain length is C12-C14, and the surfactants with straight chain structure have better performance.

Application/Function of Linear Alkyl Benzene Sulphonic Acid:

Linear alkyl benzene sulfonate has good decontamination and foam properties, and can effectively remove grease, stains and dirt. In detergents, it is usually used in combination with other surfactants to improve the cleaning capacity and foam properties of the detergent. In detergent, it can effectively clean the kitchen, toilet and other areas of oil and stains. In the field of dyes and coatings, it can be used as dispersant and emulsifier to improve the dispersion and stability of dyes and coatings. In the field of cosmetics, it can be used as emulsifier and stabilizer to improve the stability and texture of cosmetics. In the field of paper, it can be used as a lubricant and antistatic agent to improve the quality and performance of paper.

There are two main preparation methods of straight chain alkyl benzene sulfonate, one is the reaction of alkyl benzene with sulfuric acid to get alkyl benzene sulfonate, and then reaction with sodium hydroxide to get alkyl benzene sulfonate; The other is the reaction of alkyl benzene with benzene sulfonic acid to get alkyl benzene sulfonic acid, and then reaction with sodium hydroxide to get sodium alkyl benzene sulfonic acid. Among them, the product obtained by the first method has higher purity, but the reaction condition is harsh and the production cost is high. The second method has milder reaction conditions and lower production cost, but lower product purity.

Production method of Linear Alkyl Benzene Sulphonic Acid :

Pay attention to safety when using sodium linear alkyl benzene sulfonate. Avoid contact with skin and eyes. In case of accidental contact, rinse with plenty of water immediately and seek medical treatment. During the storage process, avoid direct sunlight and damp environment, and the storage temperature should not be too high.

In short, linear alkyl benzene sulfonate is an important surfactant, with good surface activity and emulsifying properties, widely used in detergent, detergent, dyes, coatings, cosmetics, paper and other fields. Pay attention to safety during use, avoid contact with skin and eyes, and keep away from direct sunlight and damp environment when storing.
