Title:
PRODUCTION OF 2, 6-DIACETOXYNAPHTHALENE
Document Type and Number:
Japanese Patent JPS63152345
Kind Code:
A
Abstract:
2,6-Diacetoxynaphthalene (DAN) is produced by subjecting 6-acetoxy-2-acetonaphthone (AAN) to a Baeyer-Villiger oxidation using a peroxy compound, e.g., peracetic acid, as oxidant under conditions such that the reaction mass contains no more than about 0.1 wt.% of a mineral acid based on the weight of the initially added pure peroxy compound. The AAN is preferably produced by subjecting 2-naphthyl acetate to a Fries rearrangement or 2-naphthol to a Friedel-Crafts acetylation, to produce 6-hydroxy-2-acetonaphthone (HAN), e.g., using hydrogen fluoride as catalyst, and acetylating the HAN, e.g., with acetic anhydride.
