Chemical properties
clear colorless liquid
The Uses of 2,2-Dichloropropane
2,2-Dichloropropane can be used to determine the occurrence and distribution of volatile organic compounds in conventional and advanced drinking water treatment processes.
General Description
Dehydrohalogenation of 2,2-dichloropropane sorbed in micropores of several model mineral solids has been investigated. Polymorphism of 2,2-dichloropropane has been investigated by thermal and X-ray powder diffraction experiments.
Purification Methods
Wash it with aqueous Na2CO3 solution, then distilled water, dry over CaCl2 and fractionally distil it. [Beilstein 1 IV 196.]
