Patent abstract
The present invention provides a novel process for highly selective preparation of 2,6-dialkyltetralin, a key precursor for 2,6-dimethylnaphthalene (2,6-DMN), which does not require an extra step for purifying various isomers obtained from the conventional processes for 2,6-DMN. The present invention is advantageous to improve the synthetic yield, to simplify the operation and thus to reduce the production cost, since different starting materials and different pathways are exploited and thus the additional steps are not necessary.
