Preparation of hemellitene (1,2,3-trimethylbenzene) and indene (2,3-dihydroindene) from C_9 aro- matic mixture by mean of precise distillation and cryogenic centrifugal separation was introduced.

By means of precise distillation of the aromatics mixture,the mixture of hemelytron and indene was obtained.

The technique has isomerization of 1,2,4-trimethylbenzen and precise distillation as a union, which is unique and feasible.
