Iodide of Spiroil.

Hydrospiroilic acid dissolves iodine in great quantities, and forms with it a brownish black fluid; the formation of hydriodic acid is however not perceptible. Iodide of spiroil may be obtained by distilling chloride or bromide of spiroil with iodide of potassium; even by rubbing these substances together decomposition commences, and by the application of heat iodide of spiroil sublimes: it is solid, of a dark brown colour, easily fusible, and shows in general the same properties with regard to solubility in water, æther and alcohol, and its relations to saline bases, as chloride and bromide of spiroil.
