Abstract
Disclosed is a method of preparing biomass-derived adiponitrile including preparing adiponitrile by subjecting biomass-derived adipamide to dehydration using a catalyst in a medium. The catalyst is configured such that a metal oxide is supported on a carrier containing porous silica with a pore diameter in a range of 5 nm to 15 nm, and the metal is molybdenum, chromium, vanadium, or combinations thereof.
Claims16
A method of preparing glucose-derived adiponitrile, the method comprising:
- (a) preparing adipamide by sequentially subjecting a glucose-derived glucaric acid salt to terminal amine group substitution, deoxydehydration, and hydrogenation;
- and
- (b) preparing adiponitrile by subjecting the adipamide to dehydration using a catalyst in a medium,
- wherein the catalyst comprises a metal oxide supported on a carrier containing porous silica with a pore diameter in a range of 5 nm to 15 nm, and
- wherein a metal of the metal oxide comprises molybdenum, chromium, vanadium, or combinations thereof.
A method of preparing biomass-derived adiponitrile, the method comprising:
- preparing adiponitrile by subjecting adipamide having 50 wt % or more of bio-based carbon according to ASTM D6866 based on a total amount of carbon to dehydration using a catalyst in a medium, and
- wherein the catalyst comprises a metal oxide is supported on a carrier containing porous silica with a pore diameter in a range of 5 nm to 15 nm, and
- wherein a metal of the metal oxide comprises molybdenum, chromium, vanadium, or combinations thereof.
A method of dehydrating a biomass-derived compound, the method comprising:
- preparing a second compound by subjecting a first compound having 50 wt % or more of bio-based carbon according to ASTM D6866 based on a total amount of carbon to dehydration using a catalyst in a medium,
- wherein the catalyst is configured such that a metal oxide is supported on a carrier containing porous silica with a pore diameter in a range of 5 nm to 15 nm,
- wherein a metal of the metal oxide comprises molybdenum, chromium, vanadium, or combinations thereof,
- wherein the first compound contains at least one amide group, and
- wherein the second compound contains at least one cyano group.
