Latest Patents

Grebenshchikov's latest patents focus on a multi-stage process for producing phenol and acetone from a cumene hydroperoxide mixture. The first patent outlines a method that involves reacting the cumene hydroperoxide mixture with a 2-hydroxybenzenesulfonic acid catalyst. This process operates at elevated temperatures and results in a mixture that includes phenol, acetone, and dicumyl peroxide. The second patent further refines this method by adding an amount of phenol approximately equal to the amount distilled from the cumene hydroperoxide mixture before the reacting step. This adjustment reduces the amount of hydroxyacetone produced, thereby improving the quality of commercial-grade phenol and its derivatives.
