Reaction Conditions:
with sulfuric acid;ethanethiol for 12 h;Reflux;Reagent/catalyst;
Steps:
1-6
Add 150 grams of 9-fluorenone, 400 grams of phenoxyethanol, 7.5 grams of ethyl mercaptan, 375 grams of ethyl cyclohexane, and 4.5 grams of concentrated sulfuric acid into a 2 liter reaction flask. Stir and heat to reflux. While reacting, reflux and separate water The reaction was stopped after 12 hours. Add 120 grams of water, cool and crystallize, stir at 05 for 2 hours, filter, rinse the filter cake with pure water until the pH of the rinse solution is neutral, and dry the filter cake to obtain 9,9-bis[4-( 2-hydroxyethoxy)phenyl]fluorene is 344.9 g, yield is 94.5%, content is 99.3%.
