Catalyst «titanium silicalite in a polymer matrix» for joint production of catechol and hydroquinone
Abstract
The paper proposes a method for a synthesis of new catalytic systems based on titanium silicalite (TS-1) for liquid phase oxidation of phenol by hydrogen peroxide. The systems provide a production of catechol and hydroquinone (1:1) with a yield of 90–92 % and allow establishing a continuous process instead of the conventional technology with periodic discharges of powdered catalyst (titanium silicalite). The method is based on the encapsulation of TS-1 in a polymer matrix (polypropylene, polyethylene, polystyrene, or their copolymers). With TS-1/polypropylene and TS-1/polystyrene used as examples, it was shown that the nature of the polymer matrix affects the catalytic properties of the system. The catalytic properties of TS-1/polypropylene and TS-1/polystyrene were compared with the properties of a commercial catalyst available from EniChem. The use of TS-1/polypropylene was shown to increase the productivity of current technologies and to significantly reduce the energy costs.
