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.
本发明提供了一种新颖的工艺,用于高度选择性地制备2,6-二烷基四氢
萘,这是
2,6-二甲基萘(2,6-
DMN)的关键前体,不需要额外的步骤来纯化从传统工艺中获得的各种异构体。本发明有利于提高合成产率,简化操作,从而降低生产成本,因为利用不同的起始材料和不同的途径,因此不需要额外的步骤。
