A mixture of water and a glycol, such as ethylene glycol, is employed as the solvent for the reaction between 1,6-dibromo-2-naphthol and an alkali metal sulfite in the preparation of 6-bromo-2-naphthol and its derivatives to effect a substantial reduction in reaction time. The glycol/water mol ratio is ordinarily in the range of 0.1-0.5/l, preferably 0.3-0.5/l.

On utilise, comme solvant, un mélange d'eau et de glycol tel que l'éthylène glycol dans la réaction s'effectuant entre 1,6-dibromo-2-naphtol et un sulfite de métal alcalin dans la préparation de 6-bromo-2-naphtol et de ses dérivés afin de réduire sensiblement le temps de réaction. Le rapport molaire glycol/eau est généralement compris entre 0,1-0,5/1, de préférence entre 0,3-0,5/1.
