Alkylation of triphenylphosphate
A process for the alkylation of triphenylphosphate by reaction of triphenylphosphate with an olefin in the presence of an effective amount of a solid acid catalyst selected from the group consisting of at least one zeolite, heteropolyacid or salt thereof, metal triflate, non-aryl group-containing metal sulfonic acid, metal halide Lewis acid, or compatible mixture of any such catalyst.
1. A process for the alkylation of triphenylphosphate by reaction of triphenylphosphate with an olefin in the presence of an effective amount of a solid acid catalyst selected from the group consisting of at least one zeolite, a metal triflate, a non-aryl group-containing metal sulfonic acid and compatible mixtures of any such catalyst.
2. A process as claimed in claim 1 wherein the catalyst is a zeolite.
3. A process as claimed in claim 1 wherein a zeolite contains protons as a Bronsted acid catalyst.
4. A process as claimed in claim 1 wherein a zeolite contains exchanged metal ions.
5. A process as claimed in claim 1 wherein a zeolite contains extra framework Lewis acid sites.
6. A process as claimed in claim 1 wherein the catalyst is a metal triflate.
7. A process as claimed in claim 1 wherein the catalyst is a non-aryl group-containing metal sulfonic acid.
8. A process for the alkylation of triphenylphosphate by reaction of triphenylphosphate with an olefin in the presence of an effective amount of a solid acid catalyst, wherein said solid acid catalyst is a heteropolyacid or salt thereof.
