High-Performance Liquid Chromatographic Determination of Naphtholsulfonic Acids
CHIMIA, 1979 A HPLC-method for the quantitative analysis of mixed solutions of 2-naphthol-5,7-disulfonic acid and 2-naphthol-7-sulfonic acid was developed. A complete reproducible separation of these compounds in a very short time could be reached by using a ...

Carboxylation of 2-Naphthol in Kerosene
Journal of the Japan Petroleum Institute, 2008 これまでの研究において，2-ナフトールのカルボキシル化をアニソール中で行うと，従来のKolbe-Schmitt反応では生成されにくい3-ヒドロキシ-2-ナフトエ酸や6-ヒドロキシ-2-ナフトエ酸が得られることを見出してきた。ここでは，6-ヒドロキシ-2-ナフトエ酸の合成を目的とし，ケロシンを用いて2-ナフトールのカルボキシル化を行い，反応温度，反応時間という反応条件およびアルカリ金属種が生成物選択性に及ぼす影響について検討した。原料のアルカリ金属種を変化させると，ナトリウム塩と比較してカリウム塩の方が収率は高い値を示した。また，6-ヒドロキシ-2-ナフトエ酸の選択率に着目すると，ナトリウム塩ではわずかに生成したのみであったが，カリウム塩では高選択率を得ることができた。カリウム塩を原料とした場合 ...

Dummy molecularly imprinted mesoporous silicates for selective adsorption of 2-naphthol
, 2015 Dummy molecularly imprinted mesoporous silicates (MIMS-2) were made by co-condensation of tetraethyl orthosilicate (TEOS) with precursors of bi-functional mimic of 2-naphthol, 2,7-dihydroxynaphthalene, around triblock copolymer surfactant Pluronic (P123)

Acta Crystallographica Section E Structure Reports Online, 2005 The title compound, C15H17NO2, is a product of a Mannich reaction involving 2-naphthol, formaldehyde and morpholine. The morpholine ring has a chair conformation and the crystal structure is stabilized by an intramolecular O—H⋯N hydrogen bond linking the naphthol OH group and the morpholine N atom.
