OriginBenzaldehyde belongs to the aromatic aldehyde chemical family, typically synthesized from toluene or benzyl chloride as starting materials. It is produced through catalytic oxidation or chlorination-hydrolysis reactions of petroleum-derived precursors.
Benzaldehyde appears as a clear colorless to yellow liquid with a bitter almond odor. Flash point near 145 °F. More denser than water and insoluble in water. Hence sinks in water. Vapors are heavier than air. The primary hazard is to the environment. Immediate steps should be taken to limit spread to the environment. Easily penetrates the soil to contaminate groundwater and nearby waterways. Used in flavoring and perfume making.
Solubility less than 0.1 mg/mL at 67.1 °F (NTP, 1992)
