Is 2-naphthol isomorphous with 2-fluoronaphthalene or with naphthalene?
Résumé
y means of X-ray diffraction and thermal analysis on the systems 2-fluoro- naphthalene - 2-naphthol and naphthalene - 2-naphthol, it is shown that the form in which 2-naphthol crystallizes from the melt is identifiable with the typical form of naphthalene. Thus, there is second compound in the naphthalenic series for which this form proves to be more stable than the structurally bordering one preferred by 2- fluoronaphthalene and most of the simple β-substituted derivatives.
