Chloral or trichloroacetaldehyde is a raw material for the manufacture of chloral hydrate and pesticides such as DDT. In its pure form it is present as an oily colorless liquid. Chloral vapors are heavier than air. Once chloral comes into contact with water, chloral hydrate, an aldehyde hydrate forms.

Toxicology

Chloral and concentrated Chlorallösungen can cause skin and mucous membrane burns. Chlorallösungen with more than 10 to 15% call forth the human skin sensitization. Inhalation of Chloraldämpfen leads to cough and choking. In severe cases, the entire respiratory tract to be damaged, some time after contact with Chloraldämpfen can also be a toxic pulmonary edema occur. In the airways, chloral can cause allergies.

Special

Chloral formed by absorption of water a stable gem- diol chloral hydrate. This is one of the few compounds that contradict the Erlenmeyer rule.
