Abstract
Official abstract text for this publication.
Provided is a method of alkylating an aromatic compound comprising contacting an aromatic compound and an alkylating agent in the presence of UCB-3 as a catalyst under reaction conditions suitable for aromatic alkylation. The aromatic compound preferably comprises benzene or toluene and the alkylation agent preferably comprises an olefin or alcohol. Lower temperature ranges can be used for the reaction, for example in the range of from 100 to 300° C.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of alkylating an aromatic compound comprising contacting an aromatic compound and an alkylating agent in the presence of a UCB-3 catalyst under reaction conditions suitable for aromatic alkylation. 2. The method of claim 1 , wherein the aromatic compound comprises benzene, toluene, or a mixture thereof. 3. The method of claim 1 , wherein the aromatic compound comprises toluene. 4. The method of claim 1 , wherein the alkylating agent comprises an alkane, olefin or an alcohol. 5. The method of claim 4 , wherein the alkylating agent comprises an olefin. 6. The method of claim 5 , wherein the olefin comprises ethylene or propylene. 7. The method of claim 5 , wherein the olefin comprises propylene. 8. The method of claim 4 , wherein the alkylating agent comprises an alcohol. 9. The method of claim 8 , wherein the alcohol comprises methanol. 10. The method of claim 8 , wherein the alcohol comprises isopropanol. 11. The method of claim 1 , wherein the contacting is at a temperature in the range of 0° C. to 500° C. 12. The method of claim 11 wherein the contacting is at a temperature in the range of 150° C. to 250° C. 13. The method of claim 11 , wherein the contacting is at a pressure in the range of 0.2 to 250 atm. 14. The method of claim 1 , wherein the aromatic compound comprises benzene. 15. The method of claim 14 , wherein the alkylating agent comprises ethylene, propylene, isopropanol or a mixture thereof. 16. The method of claim 14 , wherein the alkylating agent comprises ethylene or propylene.
