Abstract
Official abstract text for this publication.
Embodiments of the present disclosure are directed towards methods of etherification including modifying a zeolite catalyst with silica to provide a silica modified zeolite catalyst; and contacting the silica modified zeolite catalyst with an olefin and an alcohol to produce a monoalkyl ether.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of etherification, the method comprising: producing a monoalkyl ether by contacting a silica modified zeolite catalyst with an olefin and an alcohol having two or more hydroxyl groups, wherein the silica modified zeolite catalyst is modified by impregnation of a zeolite catalyst with a solution comprising a silicon compound to a silica loading from 15 to 50 weight percent based upon a total weight of the zeolite catalyst. 2. The method of claim 1 , wherein the zeolite catalyst is a zeolite beta catalyst. 3. The method of claim 1 , wherein the templates of the zeolite catalyst are removed prior to modification. 4. The method of claim 3 , wherein removal of the reducing templates comprises calcination of the of the zeolite catalyst. 5. The method of claim 1 , wherein the olefin includes from 6 to 30 carbon atoms. 6. The method claim 1 , wherein the olefin is a C 12 -C 14 olefin. 7. The method of claim 1 , wherein the alcohol is selected from the group consisting of monoethylene glycol, diethylene glycol, glycerol, and combinations thereof. 8. The method of claim 1 , wherein the silicon compound is tetramethyl orthosilicate or tetraethyl orthosilicate.
