Process for isomerization and decarboxylation of unsaturated organic compounds with a metal catalyst or catalyst precursor
Disclosed is a method for using a metal catalyst or catalyst precursor that catalyzes the isomerization of an unsaturated fatty acid, unsaturated fatty acid derivative, or an unsaturated triglyceride. Also disclosed is a method for using a metal catalyst or catalyst precursor that catalyzes the decarboxylation of an unsaturated organic compound. Also disclosed is a method for using a catalyst or catalyst precursor for the dual function isomerization and decarboxylation of an unsaturated fatty acid to an unsaturated organic compound.
Catalytic ester decarbonylation
A process of preparing olefins of the formula (I) is described herein: ##STR00001##
with R.sup.1 being a substituted or unsubstituted (C.sub.1-C.sub.30)hydrocarbyl, and R.sup.2 being a substituted or unsubstituted (C.sub.1-C.sub.20)hydrocarbyl. The process includes reacting a compound of formula (II) ##STR00002##
wherein Ar is chosen from ##STR00003##
in the presence of a palladium-based catalyst and an organic solvent. A process of preparing olefins of the formula (III) is also described: ##STR00004##
with R.sup.3 being a substituted or unsubstituted (C.sub.1-C.sub.30)hydrocarbyl, R.sup.4 being a substituted or unsubstituted (C.sub.1-C.sub.20)hydrocarbyl, and R.sup.5 being a substituted or unsubstituted (C.sub.1-C.sub.30) hydrocarbyl. The process includes reacting a compound of formula (IV) ##STR00005##
wherein Ar is chosen from ##STR00006##
with a compound of formula (V) ##STR00007##
wherein Ar is chosen from ##STR00008##
in the presence of a palladium-based catalyst and an organic solvent.
Selective Hydrogenation Catalyst and Methods of Making and Using Same
A composition comprising an extruded inorganic support comprising an oxide of a metal or metalloid, and at least one catalytically active metal, wherein the extruded inorganic support has pores, a total pore volume, and a pore size distribution, wherein the pore size distribution displays at least two peaks of pore diameters, each peak having a maximum, wherein a first peak has a first maximum of pore diameters of equal to or greater than about 120 nm and a second peak has a second maximum of pore diameters of less than about 120 nm, and wherein greater than or equal to about 5% of a total pore volume of the extruded inorganic support is contained within the first peak of pore diameters.
