Abstract
The present invention relates to a process for the one-pot hydrogenation and dehydration or isomerization of an organic compound, and to a catalyst composition for this process comprising transition metal particles having particle size below 50 nm supported on a material comprising at least one fluorinated polymer (P), wherein polymer (P) bears —SO2X functional groups, X being selected from X′ and OM, X′ being selected from the groups consisting of F, Cl, Br and I; and M being selected from the group consisting of H, and alkaline metal and NH4.
Claims19
A process for the one-pot hydrogenation and acid-catalysed isomerisation or dehydration of a substrate (I) containing at least a C═C, a C═CO an acetal, a 1,2-diol or a hemiacetal moiety to obtain a product (II), wherein said process comprises reacting the substrate (I) with hydrogen (H2) in the presence of a catalyst (III), said catalyst comprising transition metal particles having particle size below 50 nm supported on a material comprising at least one fluorinated polymer (P), wherein polymer (P) bears —SO2X functional groups, X being selected from X′ and OM, X′ being selected from the group consisting of F, Cl, Br, and I;
- and M being selected from the group consisting of H, an alkaline metal and NH4.
Use of a catalyst (III) comprising transition metal particles having particle size below 50 nm supported on a material comprising at least one fluorinated polymer (P), wherein polymer (P) bears —SO2X functional groups, X being selected from X′ and OM, X′ being selected from the group consisting of F, Cl, Br, and I;
- and M being selected from the group consisting of H, an alkaline metal and NH4, in the one-pot hydrogenation and acid-catalysed isomerisation or dehydration of a substrate (I) containing at least a C═C or C═O moiety to obtain a product (II), wherein said process comprises reacting the substrate with hydrogen (H2) in the presence of catalyst (III).
A solid composition comprising transition metal particles having particle size below 50 nm supported on a material comprising at least one fluorinated polymer (P), wherein polymer (P) bears —SO2X functional groups, X being selected from X′ and OM, X′ being selected from the group consisting of F, Cl, Br, and I;
- and M being selected from the group consisting of H, an alkaline metal and NH4, and (P) comprises recurring units derived deriving from tetrafluoroethylene (TFE) and a linear Sulfonyl Fluoride Vinyl Ether (SFVE).
