METHOD OF PRODUCING 2,6-DIMETHYL-1-NAPHTHALDEHYDE Russian patent published in 2012 - IPC C07C47/546 C07C45/49 

Abstract RU 2440967 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing 2,6-dimethyl-1-naphthaldehyde which is used in industrial chemical materials and raw materials for pharmaceutical products, pesticides, optical functional materials and electronic functional materials. The method involves formylation of 2,6-dimethylnaphthalene with carbon monoxide in the presence of hydrogen fluoride in terms of moles in amount ranging from 5- to 100-fold and boron trifluoride in terms of moles in amount ranging from 0.5- to 3.5-fold compared to the amount of 2,6-dimethylnaphthalene, and at reaction temperature ranging from 35 to 70°C.

EFFECT: method enables to obtain and end product with high selectivity.
