Chloral Usage And Synthesis

Chemical Properties

colourless oily liquid with a pungent odour

Chemical Properties

Chloral is a combustible, oily liquid with a pungent irritating odor.

Uses

manufacture of chloral hydrate, DDT.

Uses

Chloral is used in medicine as a hypnotic.

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, CCl3CH(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.

Production Methods

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.

General Description

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 Reactions

Chloral is sensitive to exposure to moisture and light. Soluble in water. Chloral reacts with water to form chloral hydrate.

Reactivity Profile

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.

Safety Profile

A poison. Mutation E data reported.

Potential Exposure

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

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Purification Methods

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.]

Incompatibilities

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.
