FAQ

What are the physical and chemical properties of Aluminum monostearate (CAS: 7047-84-9)?

Aluminum monostearate (CAS: 7047-84-9) is a white crystalline powder with a high melting point of approximately 130°C. It has a molecular weight of about 340.48 g/mol and is poorly soluble in water but soluble in organic solvents. Chemically, it is a complex of aluminum with stearic acid, showing minimal reactivity under normal conditions.

How is Aluminum monostearate (CAS: 7047-84-9) typically synthesized?

Aluminum monostearate is typically synthesized by reacting aluminum isopropoxide with stearic acid in a solvent such as toluene. The reaction is carried out under mild conditions, and the product is then purified by recrystallization. This process yields a high-quality product with good selectivity and a yield of about 80-85%.

What industries use Aluminum monostearate (CAS: 7047-84-9)?

Aluminum monostearate (CAS: 7047-84-9) is widely used in the pharmaceutical industry as a lubricant and anti-adherent agent. It is also utilized in the polymer industry as a compatibilizer and in the food industry as a stabilizer. Additionally, it is used in the cosmetic industry as a thickener and in the semiconductor industry as a protective coating.

What precautions should be taken when handling Aluminum monostearate (CAS: 7047-84-9)?

When handling Aluminum monostearate (CAS: 7047-84-9), appropriate personal protective equipment (PPE), such as gloves and safety goggles, should be worn. Ensure that the work is conducted in a well-ventilated area or a fume hood. In case of spills, use appropriate spill kits and refer to the Safety Data Sheet (SDS) for proper disposal and cleanup instructions. Avoid inhaling dust and direct contact with skin and eyes.
