−An industrial scale hexane process is designed for the implementation of a fully thermally coupled distillation column (FTCDC). A semi-rigorous material balance and Peng-Robinson equilibrium relation are utilized in the structural design. The operational design is conducted with a commercial design program, the HYSYS. The design outcome of the structural design indicates it to be comparable wi...

In the title compound, C(8)H(12)Br(4), the cyclo-hexane ring exhibits a chair conformation. The C-Br distances range from 1.964 (6) to 1.985 (5) Å and the C-C distances range from 1.496 (6) to 1.543 (7) Å. Short inter-molecular Br⋯Br contacts [3.467 (4) Å] occur in the crystal.
