They put benzaldehyde solution on a fume board near the honeycombs to make bees to move away. The synthesis of mandelic acid starts with the addition of hydrocyanic acid to benzaldehyde: The resulting cyanohydrin is hydrolysed to mandelic acid. [11] An acceptable daily intake of 15 mg/day has been identified for benzaldehyde by the United States Environmental Protection Agency. LD50 in rats, guinea pigs (mg/kg): 1300, 1000 orally (Jenner), Benzaldehyde Its solubility in water is 3 g/L. Via aldol condensations, benzaldehyde is converted into derivatives of cinnamaldehyde and styrene. How many grams are in 5 ml of benzaldehyde? The bees then move away from the honey combs to avoid the fumes. He extracted the substance from bitter almonds. It is a colorless liquid with a characteristic almond-like odor.
