Abstract
The invention relates to producing ortho isopropyl phenol catalytically by contacting phenol with isopropanol or propylene, at a temperature of from about 200.degree. C. to about 300.degree. C., with ZSM-12 and zeolite Beta; and recovering ortho isopropyl phenol.
Claims16
A process for producing ortho isopropyl phenol, comprising
- contacting a feedstream, with a catalyst, at a temperature of from about 200.degree. C. to about 300.degree. C.,
- wherein the feedstream comprises phenol and at least one compound selected from the group consisting of isopropyl alcohol or propylene, and wherein the catalyst comprises a zeolite, in the hydrogen from,
- wherein the zeolite is selected from the group consisting of ZSM-12 and zeolite BETA;
- and
- recovering ortho isopropyl phenol.
