Reaction Conditions

Reaction Steps

In the dehydrogenation apparatus described in Example 2 the preheating zone was heated to a temperature of 480° C. and the reaction and afterheat zone were heated to a temperature of 520° C. 400 ml molten sym.-octahydroanthracene (385 g) of Example 3 were added drop by drop per hour from a drip funnel heated to 95° C. At the same time about 4 liter hydrogen per hour were added as a carrier gas. 372 g of raw anthracene were obtained per hour, which contained as impurities 1.8 percent 9,10-dihydroanthracene, 2.5 percent 1,2,3,4-tetrahydroanthracene, 2.6 percent sym.-octahydroanthracene and 2.9 percent phenanthrene.
