Benzaldehyde | CAS No. 100-52-7

Q: What are the physical and chemical properties of Benzaldehyde (CAS: 100-52-7)?

Benzaldehyde is a colorless liquid with a distinctive almond-like odor. Its molecular weight is approximately 106.12 g/mol. It has a melting point of -26°C and a boiling point of 178.2°C. Benzaldehyde is slightly soluble in water but miscible with ethanol and ether. It is highly reactive, particularly towards nucleophiles and reducing agents.

Q: How is Benzaldehyde (CAS: 100-52-7) typically synthesized?

Benzaldehyde is commonly synthesized via the hydrolysis of toluene dioxide, a process known as Kolbe-Schmitt reaction. Another method involves the oxidation of toluene with a silver catalyst. These processes provide good yields and selectivity, making them suitable for industrial production.

Q: What industries use Benzaldehyde (CAS: 100-52-7)?

Benzaldehyde is widely used in the food and flavor industry as a flavoring agent. It is also employed in the pharmaceutical industry for the synthesis of certain drugs. Additionally, it finds applications in the production of perfumes, dyes, and as a chemical intermediate in the manufacture of polymers and semiconductors.

Q: What precautions should be taken when handling Benzaldehyde (CAS: 100-52-7)?

When handling benzaldehyde, appropriate personal protective equipment (PPE) should be worn, including gloves, safety goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood to minimize exposure. Spills should be cleaned up using appropriate absorbent materials, and the area should be well-ventilated. Always consult the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
