Abstract
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.
Claims8
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.
