n-Dodecylbenzene - Introduction
Dodecylbenzene, also known as phenyl stearate, is an organic compound with the chemical formula C18H30.
Nature:
1. Appearance: Colorless or yellowish liquid with special smell.
2. Density: about 0.862 g/mL.
3. Solubility: Soluble in organic solvents, such as alcohols, ethers and aromatic hydrocarbons.
4. Stability: good stability, not easy to decompose.
Use:
1. Lubricant: It is commonly used as an additive for high temperature lubricating oil and grease, which can improve the viscosity and high temperature resistance of the product.
2. Cosolvent and mixed solvent: can be used in cosmetics, coatings, adhesives and other fields, with good solubility and miscibility.
3. Antioxidant: can be used in rubber and plastic products, can prevent its aging and deterioration.
Preparation Method:
dodecyl benzene is generally obtained by The alkylation reaction of benzene and dodecane. The commonly used alkylation reagents include propenyl chloride, ferrous sulfate and composite aluminum chloride.
Safety Information:
1. Dodecyl benzene is mildly irritating. Avoid direct exposure to skin and eyes when in contact. If in contact, please rinse with water immediately.
2. During operation, wear protective glasses, gloves and protective clothing to ensure good ventilation.
3. Should be away from the fire and high temperature environment, to avoid the generation of combustible steam.
4. Should be sealed when stored, avoid contact with oxygen, oxidant and strong oxidant, so as not to cause fire or explosion.
Please note that the above information is for reference only. Relevant literature and material safety data sheets should be consulted before specific operation.
