Abstract
A process for preparing .beta.-naphthyl benzyl ether comprises reacting .beta.-naphthol essentially in the absence of water with an alkali metal carbonate or an alkaline earth metal carbonate and benzyl chloride in an inert water-miscible solvent at from 0.degree. to 200.degree. C.
Claims5
A process for preparing .beta.-naphthyl benzyl ether which comprises:
- reacting .beta.-naphthol essentially in the absence of water with an alkali metal carbonate or an alkaline earth metal carbonate and benzyl chloride in an inert water-miscible solvent at from 60.degree. C. to 200.degree. C.;
- and
- after the reaction has ended, admixing the reaction mixture with water at a temperature of 30.degree. C. to 110.degree. C. only to the onset of crystallization of the .beta.-naphthyl benzyl ether product and thereafter cooling the reaction mixture to a temperature of from 0.degree. C. to 25.degree. C. to cause crystallization and precipitation of said ether product.
