Good Quality Benzenesulfonic acid, C10-13-alkyl derivs., sodium salts CAS NO 68411-30-3

Chemical Identity: Benzenesulfonic Acid, C10-13-Alkyl Derivatives, Sodium Salts (CAS No. 68411-30-3) Description: Benzenesulfonic acid, C10-13-alkyl derivatives, sodium salts, also known as linear alkylbenzene sulfonates (LAS), are anionic surfactants commonly used in household and industrial cleaning products. They are derived from the sulfonation of linear alkylbenzenes (LAB) followed by neutralization with sodium hydroxide.

Physical Properties: Description: Linear alkylbenzene sulfonates typically appear as colorless to light yellow liquids or powders. They are soluble in water and exhibit excellent detergent properties. Their physical properties, such as solubility and viscosity, may vary depending on the alkyl chain length and degree of sulfonation.

Chemical Structure: Description: The chemical structure of linear alkylbenzene sulfonates consists of a linear alkyl chain (C10-C13) attached to a benzene ring, which is sulfonated to form the sulfonate group (-SO3Na). The sodium ion (Na+) is ionically bonded to the sulfonate group.

Synthesis Method: Description: Linear alkylbenzene sulfonates are synthesized through the sulfonation of linear alkylbenzenes (LAB) with sulfur trioxide or sulfuric acid, followed by neutralization with sodium hydroxide. The reaction yields sodium salts of the sulfonated alkylbenzenes.

Applications in Cleaning Products: Description: Linear alkylbenzene sulfonates are widely used as surfactants and detergents in household and industrial cleaning products, including laundry detergents, dishwashing liquids, and household cleaners. They effectively remove oil, grease, and dirt from surfaces.

Biodegradability: Description: Linear alkylbenzene sulfonates are readily biodegradable under aerobic conditions in natural environments. They break down into simpler compounds through microbial action, reducing their environmental impact compared to some other surfactants.

Performance Characteristics: Description: Linear alkylbenzene sulfonates exhibit excellent cleaning and foaming properties over a wide range of water hardness and temperatures. They are compatible with other detergent ingredients and can enhance the overall performance of cleaning formulations.

Toxicological Considerations: Description: Linear alkylbenzene sulfonates are considered safe for use in household cleaning products when used according to recommended guidelines. However, exposure to concentrated solutions may cause skin and eye irritation. Proper handling and storage are essential to minimize risks.

Regulatory Status: Description: Linear alkylbenzene sulfonates are regulated by government agencies such as the EPA in the United States and the European Chemicals Agency (ECHA) in the European Union. Compliance with regulations and guidelines is necessary for their safe use and disposal.

Safety Precautions: Description: When handling linear alkylbenzene sulfonates in concentrated form, appropriate personal protective equipment such as gloves and safety goggles should be worn to prevent skin and eye contact. Avoid inhalation of dust or aerosols. In case of accidental exposure, rinse affected areas thoroughly with water and seek medical attention if irritation persists.
