Chemische Eigenschaften
Chloral is a combustible, oily liquid with a
pungent irritating odor.
Verwenden
manufacture of chloral hydrate, DDT.
Vorbereitung Methode
Chloral can be prepared by action of Cl2 on ethanol, chlorination of acetaldehyde, oxidation of 1,1,2-trichloroethylene in the presence of a catalyst (FeCl3, AlCl3, TiCl4 or SbCl3, and by reaction of CCl4 with formaldehyde.
Definition
A colorless liquid aldehyde made by chlorinating
ethanal. It was used to make the insecticide
DDT. It can be hydrolyzed to give 2,2,2-
trichloroethanediol (chloral hydrate,
CCl
3CH(OH)
2). Most compounds with
two –OH groups on the same carbon atom
are unstable. However, in this case the effect of the three chlorine atoms stabilizes
the compound. It is used as a sedative.
Allgemeine Beschreibung
A colorless oily liquid with a penetrating odor. Reacts with water and denser than water. Contact may irritate skin, eyes and mucous membranes. Toxic by ingestion and inhalation. Used to make pesticides.
Air & Water Reaktionen
Chloral is sensitive to exposure to moisture and light. Soluble in water. Chloral reacts with water to form chloral hydrate.
Reaktivität anzeigen
Chloral reacts with water to form chloral hydrate. Chloral polymerizes under the influence of light and in the presence of sulfuric acid forming a white solid trimer called metachloral.
Hazard
Toxic by ingestion. Probable carcinogen.
Health Hazard
INHALATION: Sore throat, shortness of breath, drowsiness, irritation of respiratory tract, unconsciousness. EYES: Redness, pain and blurred vision. SKIN: Redness and pain. INGESTION: Dizziness, drowsiness, nausea, and unconsciousness. Acute hazard: Poison may be fatal if inhaled, swallowed, or absorbed through skin.
Sicherheitsprofil
A poison. Mutation
E data reported.
mögliche Exposition
Chloral is used as an intermediate
in the manufacture of such pesticides as DDT, methoxychlor, DDVP, naled, trichlorfon, and TCA. Chloral is
also used in the production of chloral hydrate; used as
a therapeutic agent with hypnotic, sedative, and narcotic
effects; used in a time prior to the introduction of
barbiturates

Class: 6.1; Labels: 6.1-Poisonous materials, Technical
Name Required.
läuterung methode
Distil chloral, then dry it by distilling through a heated column of CaSO4. [Beilstein 1 H 616, 1 I 328, 1 II 467, 1 III 2663, 1 IV 3142 for anhydr, 1 IV 3143 for hydrate.]
Inkompatibilitäten
Chloral hydrate reacts with strong bases
forming chloroform. Contact with acids, or exposure to
light may cause polymerization. Reacts with water, forming
chloral hydrate. Reacts with oxidizers, with a risk of fire or
explosions.
Waste disposal
Incineration after mixing with
another combustible fuel; care must be taken to assure complete combustion to prevent phosgene formation; an acid
scrubber is necessary to remove the halo acids produced.
