日期:——
In the Friedel–Crafts acetylation of 2-methylnaphthalene all seven possible isomers are formed, their proportions depending on the experimental conditions. The yields of the isomers vary within the limits given in parentheses : 1 -(0·3–33%), 3-(0·8–14%), 4-(0·8–5·5%). 5-(0·4–2·0%), 6-(7·4–73%), 7-(4·2–58%), and 8-(9–59%). Competitive acetylation experiments in chloroform solution at 20° gave the following

lower aliphatic carboxylic acid solvent and a catalyst comprising a heavy metal and a bromine compound. By regulating the ratio of the total number of bromine atoms fed into a reaction system to the total number of 1,3-dialkylnaphthalene molecules fed into the reaction system within a specific range, 1,3-naphthalenedicarboxylic acid is efficiently produced with low costs. Using 1,3-dimethylnaphthalene, as the starting 1,3-dialkylnaphthalene, which is produced by isomerizing dimethylnaphthalenes in a liquid phase in the presence of a catalyst comprising hydrogen fluoride and boron trifluoride together with a C
