Reaction Conditions:
with hydrogenchloride in Zinc chloride;lithium hydroxide monohydrate;isopropanol;
Steps:
4 9,9-bis-(4-hydroxyphenyl)-fluorene
EXAMPLE 4 9,9-bis-(4-hydroxyphenyl)-fluorene 20 moles of phenol containing 9% by weight of water were stirred in an autoclave and then one mole of zinc chloride and 10 moles of fluorenone were dissolved therein. Then, 5 moles of gaseous hydrogen chloride were added to the stirred mixture and the mixture was reacted at 70° C. for 4 hours. The reaction mixture was then dissolved in 5 liters of isopropanol at 60° C. and the solution was poured with vigorous stirring into a ten-fold volume of water to precipitate 3.4 kg of 9,9,-bis-(4-hydroxyphenyl)-fluorene (97% yield in the form of a yellow product.
