121-65-3 - Introduction
DODECYLBENZENESULFONIC ACID, also known as stearic acid benzenesulfonic ACID (Dodecylbenzenesulfonic acid), is an organic compound. The following is a description of its nature, use, preparation and safety information:
1. Nature:
-Appearance: DODECYLBENZENESULFONIC ACID is a white crystalline or powdery solid.
-Solubility: It is easily soluble in water and some organic solvents, such as alcohols and Ether solvents.
-Acidic: It is a strong acid that can react with alkali to form the corresponding salt.
2. Use:
-Surfactant: Because dodecylbenzensulfonic ACID has good surface activity, it can be used as a raw material for the synthesis of other surfactants, such as detergents, detergents and emulsifiers.
-Catalyst: As a catalyst for the sulfation reaction of hard fats, it is commonly used in rubber processing, synthetic resins and dye industries.
3. Preparation method:
- DODECYLBENZENESULFONIC ACID can be prepared by benzylation, sulfonation and hydrolysis. First, benzene sulfuric acid is reacted with dodecane to produce the corresponding alkylbenzene sulfonic acid through an alkylation reaction. Then, the sulfonated product is hydrolyzed with an alcohol or a base to obtain 4-dodecylbenzenesulfonic acid.
4. Safety Information:
- DODECYLBENZENESULFONIC ACID is an organic ACID, which is irritating and should be protected when used.
-Long-term or heavy exposure may cause irritation to the skin, eyes, and respiratory system.
-Wear safety gloves, goggles and protective clothing during handling and use, and ensure good ventilation.
-Do not mix with strong oxidants or combustibles to avoid dangerous reactions.
