HCN:
Citat:
Hydrogen cyanide [74-90-8] (hydrocyanic acid, prussic acid, formonitrile), HCN, is a colorless, poisonous, low viscosity liquid having an odor characteristic of bitter almonds. It was prepared in dilute solution by Scheele in 1782 and as the pure compound by Gay-Lussac in 1815. The compound has been known and used as a poison for decades. In England, hydrogen cyanide was sold in small crates of glass bottles for the fumigation of old furniture being rehabilitated for sale as antiques. In the United States, hydrogen cyanide was used for fumigation in the orange groves in California. It was transported to the groves by horse-drawn carts in milk cans. Although until the 1960s hydrogen cyanide was used as a fumigant in grain silos, this use has virtually disappeared. Hydrogen cyanide is used, however, in the manufacture of many important chemicals.

Bensaldehyd:
Citat:
Benzaldehyde [100-52-71] C6H5CHO, is the simplest and quite possibly the most industrially useful member of the family of aromatic aldehydes. Benzaldehyde exists in nature, primarily in combined forms such as a glycoside in almond, apricot, cherry, and peach seeds. The characteristic benzaldehyde odor of oil of bitter almond occurs because of trace amounts of free benzaldehyde formed by hydrolysis of the glycoside amygdalin. Amygdalin was first isolated in 1830 from the seeds of the bitter almond (Prunus amygdalus). Sometime later, Liebig and Whler found that when amygdalin was hydrolyzed with water and emulsin, benzaldehyde, hydrogen cyanide, and D-glucose were formed.
