ABSTRACT:
The selective formation of 2-acetonaphthalene is achieved by acetylating naphthalene in the presence of liquid hydrogen fluoride. The 2-acetonaphthalene can be separated from the formed 1-acetonaphthalene isomer by successive hydrogenation of the isomer mixture and dehydration. The hydrogenation is selective to the 2-isomer while the 1-acetonaphthalene remains unreacted. Upon completion, 2-vinylnaphthalene can be distilled off from the unreacted 1-acetonaphthalene.
