CHLORALUM HYDRATUM 



Synonyms. Chloral, Chloral Hydrate 



Properties. Chloral hydrate is prepared by the union of a 

 molecule of water with trichlor aldehyde (chloral), the latter being 

 a product of the action of chlorine on alcohol. It occurs as sepa- 

 rate rhomboidal crystals, having an aromatic, acrid, penetrating 

 odor and bitterish caustic taste. It is slightly volatile when exposed 

 to the air, is freely soluble in water, alcohol, ether, chloroform, and 

 the fixed and fatty oils, and liquefies when triturated with camphor, 

 menthol, thymol or phenol. It decomposes in strongly alkaline solu- 

 tions, liberating chloroform.
