[PROBLEMS] To economically produce DCT isomers from a DCT isomer mixture. A 2,3-DCT is obtained from a mixture of DCT isomers. And 3,4-DCT are separated by distillation, and 2,3-DCT 2,6-DCT, 2,5-DCT, 2,4-DC from DCT isomer mixtures poor in T and 3,4-DCT concentrations By separating at least one DCT isomer of T by an adsorption separation method, each DCT isomer can be produced economically. |
