Description

Paraldehyde was first synthesized in 1829 by Wildenbusch and introduced into clinical practice in the United Kingdom by the Italian physician Vincenzo Cervello in 1882. Paraldehyde, a polymer of acetaldehyde, is a clear colorless or slightly yellow transparent liquid with a strong aromatic as well as a disagreeable taste that at low temperatures, it solidifies into a crystalline mass. This agent decomposes with strong into toxic products that may be released into water, soil, or atmosphere.
