Zusammenfassung:FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to a method for preparing phenylacetone by interaction of phenylacetic acid with acetic acid in gaseous phase in their mole ratio = 1:(2-5) on catalyst comprising a mixture of calcium oxide and magnesium oxide at temperature 350oC, not below. Loading on catalyst is 2.2-2.8 kg of the parent mixture/(kg cat h). Method provides elevating yield up to 79.9-82.6%. ^ EFFECT: improved preparing method, increased yield. ^ 5 ex
