ABSTRACT:
Naphthyl acetals are made by reacting a naphthol with an alkyl vinyl ether under the influence of an aliphatic acid catalyst. For example n-butyl-1-naphthyl acetal is made by reacting 1-naphthol with n-butyl vinyl ether in the presence of up to about 5 mole percent, based on moles of naphthol, of a weak organic acid such as acetic acid or other aliphatic monocarboxylic acids.
