Sodium 1-undecanesulphonate - Introduction
Sodium 1-undecanesulfonate (sodium 1-undecanesulfonate) is an organic compound with the chemical formula C11H23SO3Na. The following is a description of the nature, use, formulation and safety information of Sodium 1-undecanesulfonate:
Nature:
-Appearance: White crystalline powder or granules.
-Solubility: Soluble in water and polar organic solvents, such as alcohols and ethers.
-Stability: Unstable when encountering strong acids and strong oxidants.
Use:
-Surfactant: Sodium 1-undecanesulfonate has good surface active properties and is often used as a detergent, foaming agent and emulsifier.
-Analytical Chemistry: It can be used for the separation and determination of various ions in ion exchange chromatography.
Preparation Method:
There are two main ways to synthesize Sodium 1-undecanesulfonate:
-alkyl bromination: undecane (undecane) is reacted with bromine to obtain n-undecane (1-bromonecane), which is then reacted with sulfuric acid to generate n-undecyl sulfonic acid, and finally reacted with sodium hydroxide to obtain Sodium 1-undecanesulfonate.
-sulfonation reaction: reacting n-undecane with sulfur trioxide to generate n-undecyl sulfonic acid, and then reacting with sodium hydroxide to obtain sodium 1-undecanesulfonate.
Safety Information:
Sodium 1-undecanesulfonate is generally safer during regular use, but the following matters should also be paid attention:
-May cause irritation to eyes and skin, rinse with water immediately after contact.
-Wear appropriate protective equipment such as gloves and goggles during use.
-Avoid inhaling dust and operate in a well-ventilated place.
-Avoid contact with strong acids and oxidants.
-If swallowed by accident, seek medical attention immediately.
