Chemical Properties
Colorless or slightly yellow liquid.
Slightly soluble in water; soluble in alcohol and
ether.
Uses
1-Chloro-3-Methylbutane, usually also containing normal amyl
chloride. Solvent (nitrocellulose, varnishes, lacquers, neoprene), rotogravure inks, soil fumigation,
organic compounds.
Definition
Any of several compounds or mixtures thereof may
be referred to by this name, since numerous isomers
are possible, the most common of which is 1-chloro-
3-methylbutane. Combustible.
Purification Methods
Shake the chloride vigorously with 95% H2SO4 until the acid layer no longer becames coloured during 12hours, then wash it with water, saturated aqueous Na2CO3, and more water. Dry it with MgSO4, filter and fractionally distil it. Alternatively, a stream of oxygen containing 5% of ozone is passed through the chloride for a time, three times longer than is necessary to cause the first coloration of starch iodide paper by the exit gas. Subsequent washing of the liquid with aqueous NaHCO3 hydrolyses the ozonides and removes organic acids. After drying and filtering, the isoamyl chloride is distilled.
