olimeri Europa developed the PBE-1 catalyst for use in this reaction.
olimeri Europa developed the PBE-1 catalyst for use in this reaction. Most modern forms of this process uses a modified and regenerable form of beta-zeolite as a catalyst in a fixed bed reactor, in the trademarked refinement called Q-MAX. An unstable intermediate process is kept in liquid form using 5 atm of pressure, and the products of this process are often used to make polycarbonates. This reaction has traditionally used a dangerous solid phosphoric acid catalyst. It has nothing to do with hydrazine, but an alternative to this process that produces the same product is named for Raschig and Hooker. In one step of this reaction, (*) hydroperoxide is hydrolysed in the presence of a Lewis acid to facilitate a Hock rearrangement, and it ends in a decomposition which also yields acetone as a co-product. Its first step uses a Friedel-Crafts alkylation by propylene to produce its namesake intermediate. For 10 points, name this ubiquitous means of producing phenol.
