Highly Selective Removal of Trace Isomers by Nonporous Adaptive Pillararene Crystals for Chlorobutane Purification.

Removal of trace chlorobutane (CB) isomers is highly desired to produce high grade 1-chlorobutane (1-CB) and 2-chlorobutane (2-CB). Here we report that nonporous adaptive crystals (NACs) of perethy...
