1,3-DIMETHYLCYCLOHEXANE Chemical Properties,Usage,Production

Chemical Properties

clear colorless liquid

Uses

1,3-Dimethylcyclohexane was used to study ring opening reaction of 1,3-dimethylcyclohexane over Iridium catalysts modified by the addition of K and Ni.

General Description

cis-1,3-Dimethylcyclohexane undergoes ring opening reaction via dicarbene mechanism in the presence of iridium catalyst supported on SiO₂.
