Latest Patents

Grebenshchikov's latest patents focus on innovative methods for the production of phenol and acetone from a cumene hydroperoxide mixture. The first patent describes a two-stage process involving serially connected reactors. The first stage includes the decomposition of the cumene hydroperoxide mixture in the presence of a catalyst mixture, leading to the formation of a dicumyl peroxide mixture. The second stage involves the formation of a phenol and acetone mixture from the decomposition of the dicumyl peroxide mixture. This method significantly reduces the yield of hydroxyacetone, which can negatively impact the quality of commercial phenol. The second patent reiterates this process while emphasizing the reduction of sulfuric acid consumption compared to traditional methods.
