Abstract
A process is disclosed for producing of diethyl ether by dehydrating ethanol in the presence of an inventive catalyst. A preferred catalyst achieves high conversions of ethanol and high selectivites to diethyl ether. The diethyl ether may be used as a solvent, fuel additive, or fuel.
Claims20
A process for producing diethyl ether comprising:
- dehydrating ethanol in the vapor phase at a pressure and a temperature in the presence of a catalyst to form diethyl ether, the catalyst comprising tin impregnated on a solid catalyst material selected from the group consisting of titania, zeolite, phosphotungstate and hydrotalcite.
A process for producing diethyl ether comprising:
- dehydrating ethanol in the vapor phase at a pressure and a temperature in the presence of a catalyst to form diethyl ether, wherein the catalyst is selected from the group consisting of:
- (i) germanium impregnated on a solid catalyst material, wherein the solid catalyst material is selected from the group consisting of alumina and a zeolite;
- (ii) a Group IA metal selected from the group consisting of lithium, sodium, cesium and potassium, wherein the Group IA metal is impregnated on a silica support;
- (iii) a Group IA metal selected from the group consisting of lithium, sodium and potassium, wherein the Group IA metal is impregnated on a magnesium oxide solid catalyst material;
- and
- (vi) copper impregnated on a hydroxyapatite solid catalyst material.
