PRODUCTION OF 9,9-BIS(4-(2-HYDROXYPROPOXY)PHENYL)FLUORENE

摘要

PROBLEM TO BE SOLVED: To produce the subject compound by an economically advantageous process suitable for industrial production by reacting fluorenone with phenoxypropanol using sulfuric acid and a thiol as catalysts. SOLUTION: The objective compound of the formula is produced by reacting fluorenone with phenoxypropanol in the presence of a catalyst comprising 10-500 ml of sulfuric acid (having a concentration of >=75%, preferably >=95%) and 0.01-100 ml of a thiol (e.g. a 1-10C mercaptan or 2-11C mercaptocarboxylic acid) based on 1 mol of fluorenone preferably in a water-immiscible organic solvent such as toluene at 30-150 deg.C, preferably 40-100 deg.C for 1-10 hr, preferably 3-6 hr in the case of performing the reaction by batch process.
