METHOD FOR RECOVERING MATERIAL VALUES FROM BISPHENOL TARS |
摘要 |
<p>Phenol and isopropenylphenol are recovered from BPA tars by sparging the fluidized BPA tar while heating in the presence of a basic catalyst. Sparging dramatically increases the efficiency of phenol and isopropenylphenol recovery. Recovered isopropenylphenol may be converted to bisphenol A in the distillate by reaction with phenol and an acidic catalyst.</p> |
