FIELD: petroleum chemical technology.
SUBSTANCE: invention relates to utilization of phenolic resin and preparing additional amounts of cumene, phenol and α-methylstyrene. For this aim phenolic resin containing less 0.2 wt.-% of salts is subjected for thermocatalytic decomposition in the range of temperatures 420-550oC in the presence of steam on catalyst comprising the following components, wt.-%: aluminum, oxide, 5.0-30.0; iron oxide, 0.4-1.0; magnesium oxide, 0.4-1.0; calcium oxide, 5.2-7.0; sodium oxide, 1.0-3.0; potassium oxide, 1.0-3.0; titanium (IV) oxide, 0.4-1.0; silicon (IV) oxide, 0.4-1.0, the balance, up to 100%. The proposed method provides preparing 61.5 wt.-% of useful products - cumene, phenol and α-methylstyrene for a single run. Invention can be used in the process for combined preparing phenol and acetone by cumene method.
EFFECT: improved preparing method.
