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.

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.

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.

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.
