Versuchsvorschrift

An autoclave equipped with stirrer is charged with 1,240 parts of β-naphthol, 608 parts of aqueous sodium hydroxide solution (50% strength by weight), 27 parts of aqueous potassium hydroxide solution (85% strength by weight) and 12 parts of the tetrasodium salt of ethylenediaminetetraacetic acid (dissolved in 50 parts of water). The charge is mixed thoroughly under nitrogen and heated until the internal temperature reaches 260° C. 520 parts of 2-hydroxy-naphthalene-3-carboxylic acid (corresponding to 74% of theory, based on β-naphthol converted) are obtained analogously to Example 1. The proportion of resin formed is 11 mole percent, based on β-naphthol employed. 700 parts of β-naphthol are recovered.
