Zusammenfassung:FIELD: chemistry. ^ SUBSTANCE: method includes two-stage acid-catalysed decompounding of cumene hydroperoxide in series reactors under heat resulted in simultaneous generation dicumene peroxide in the first stage followed with its decompounding in reaction medium environment in the second stage. Thus any catalytic agent is not used; it is prepared in separate reactor immediately prior to introduce to the first reactor of cumene hydroperoxide decompounding by mixing sulphuric acid with phenol in ratio 2:1 to 1:1000 and keeping produced mixture at temperature 20-80C within 1-600 minutes. ^ EFFECT: method allows for considerable yield reduction of hydroxyacetone. ^ 4 cl, 7 tbl, 6 ex
