==Properties and reactions== Dichloroacetaldehyde is a highly volatile liquid that is easily soluble in water to form Hydrates. A geminal diol, also known as monohydrate, 2,2-dichloro-1,1-ethanediol, is formed in water. 300px|Hydration of the aldehyde The compound decomposes when heated. In the presence of Lewis acids such as antimony trichloride, iron(III) chloride, aluminum trichloride, tin(IV) chloride or boron trifluoride, the trimer hexachloroparaldehyde (2,4,6-tris(dichloromethyl)-1,3,5-trioxane) can be obtained. The trimer forms colourless crystals that melt at 131–132 °C. At the boiling point of 210–220 °C, dichloroacetaldehyde decomposes. 400px|Formation of hexachloroparaldehyde Reduction with lithium aluminium hydride gives dichloroethanol.
