| titleOfInvention | Prepare the method for phenol and acetone |
| abstract | A kind of method being prepared phenol and acetone by cumene hydroperoxide mixture, described method comprises: decomposition of cumene hydroperoxide mixture under the existence of catalyst mixture, obtain the mixture comprising phenol and acetone, described method comprises further: a) pass through to merge sulfuric acid and phenol formation catalyst mixture with weight ratio 2: 1-1: 1000 in catalyzer forming reactions device; B) in the temperature of about 20-80 DEG C, catalyst mixture is kept 1-600 minute in catalyzer forming reactions device; C) catalyst mixture is joined in cumene hydroperoxide mixture, form phenol and acetone mixture.Carry out the method by this way, decrease the output of pyruvic alcohol, and therefore improve the quality of commodity phenol.In addition, with use sulfuric acid as catalyzer method compared with, this approach reduces the consumption of sulfuric acid. |
