Abstract
The invention is directed to a catalyst, to a method for manufacturing a catalyst, to a method for manufacturing a bisphenol compound, and to the use of a catalyst. The catalyst of the invention comprises particles having a core and a shell, wherein the shell comprises an ion exchange resin covering the core at least in part and wherein the core has a density that is higher than the density of the ion exchange resin.
Claims14
A catalyst for the manufacture of a bisphenol from phenol and a ketone, comprising particles having a core and a shell, wherein the shell comprises an ion exchange resin covering the core at least in part and wherein the core has a density that is higher than the density of the ion exchange resin, wherein the core of the particles has a density of at least 2500 kg/m3, wherein the core of the particles has an average particle diameter of 500-1500 μm as determined with microscopy.
A catalyst for the manufacture of a bisphenol from phenol and a ketone, comprising particles having a core and a shell, wherein the shell comprises an ion exchange resin covering the core at least in part and wherein the core has a density that is higher than the density of the ion exchange resin, wherein the core of the particles has a density of at least 2500 kg/m3, wherein the shell of the particles has an average layer thickness of 100-1000 μm as determined with microscopy.
A catalyst for the manufacture of a bisphenol from phenol and a ketone, comprising particles having a core and a shell, wherein the shell comprises an ion exchange resin covering the core at least in part and wherein the core has a density that is higher than the density of the ion exchange resin, wherein the core of the particles has a density of 2500-4500 kg/m3.
