Abstract
Description
Claims (3)
- 2. The method of claim 1 wherein the hexahalogenated dihydronaphthalene is prepared by halogenating a tetrahalo-tetrahydronaphthalene by treatment with a halogen in the presence of a light catalyst.
- 3. The method of claim 1 wherein the hexahalogenated dihydronaphthalene is prepared by treatment of naphthalene with a halogen in the presence of a light catalyst.
- 4. The method of claim 1 wherein the hydrolysis is carried out at a temperature of between about 90* to 120* C.
