Abstract

A composition comprising olefin oligomers of one or more olefin monomers, the olefin monomers comprising a branched C10 olefin monomer comprising i) 3-propyl-1-heptene, ii) 4-ethyl-1-octene, iii) 5-methyl-1-nonene, or iv) any combination thereof. A composition comprising substantially hydrogenated olefin oligomers, wherein the olefin oligomers are oligomers of one or more olefin monomers, the olefin monomers comprising a branched C10 olefin monomer comprising i) 3-propyl-1-heptene, ii) 4-ethyl-1-octene, iii) 5-methyl-1-nonene, or iv) any combination thereof. A process comprising a) contacting 1) a catalyst system and 2) a monomer feedstock comprising a branched C10 olefin monomer comprising i) 3-propyl-1-heptene, ii) 4-ethyl-1-octene, iii) 5-methyl-1-nonene, or iv) any combination thereof in a reaction zone; and b) forming olefin oligomers.

First claim

What is claimed is:

1. A process comprising a) contacting 1) a catalyst system and 2) a monomer feedstock comprising branched C 10 olefin monomers comprising i) 3-propyl-1-heptene, ii) 4-ethyl-1-octene, and iii) 5-methyl-1-nonene; and b) forming olefin oligomers; wherein the olefin oligomers have a 100° C. kinematic viscosity of from 1.5 cSt to 12 cSt; or from 15 cSt to 40 cSt,
wherein the catalyst system is selected from the group consisting of (a) a catalyst system comprising BF 3 , (b) a catalyst system consisting essentially of (i) an alkylaluminum halide, an aluminum trihalide, or any combination thereof and (ii) a promoter selected from the group consisting of water, an alcohol, a carboxylic acid, an ester, a ketone, an ether, a halogenated hydrocarbon, and any combination thereof, (c) a supported metal oxide consisting essentially of chromium oxide supported on an inert support where the inert support comprises silica, alumina, titania, silica alumina, magnesia, or combinations thereof, (d) a catalyst system comprising an acidic ionic liquid, (e) a catalyst system comprising a metallocene, (f) a catalyst system comprising a clay, an acidic clay, or an acid washed clay, and (g) an acidic ion exchange resin.

2. The process of claim 1 , wherein the monomer feedstock further comprise 1) a linear internal C 10 olefin monomer selected from 4-decene, 5-decene, or any combination thereof and/or 2) linear internal C 14 olefin monomers, branched C 14 olefin monomers, or any combination thereof.

3. The process of claim 1 , wherein the branched C 10 olefin monomer comprises i) at least 10 mol % 3-propyl-1-heptene, ii) at least 7 mol % 4-ethyl-1-octene, iii) at least 24 mol % 5-methyl-1-nonene, and iv) at least 3 mol % 2-butyl-1-hexene.

4. The process of claim 1 , wherein the monomer feedstock further comprise less than or equal to 75 mol % of at least one C 6 to C 18 normal alpha olefin monomer.

5. The process of claim 4 , wherein the C 6 to C 18 normal alpha olefin monomer comprises 1-octene, 1-decene, 1-dodecene, or any combination thereof.

6. The process of claim 5 , further comprising:
removing a reaction zone effluent from the reaction zone and optionally contacting the reaction zone effluent with a catalyst system deactivating agent to form a deactivated reaction zone effluent, and
removing at least a portion of the monomer feedstock from the reaction zone effluent or deactivated reaction zone effluent.

7. The process of claim 6 , further comprising:
isolating one or more fractions comprising all or a portion of the olefin oligomers from the reaction zone effluent or deactivated reaction zone effluent, and
hydrogenating at least one of the one or more fractions comprising all or a portion of the olefin oligomers.

8. The process of claim 1 , wherein the monomer feedstock comprises 1) at least 80 mol % branched C 10 olefin monomer, the branched C 10 olefin monomer comprising i) from 10 mol % to 32 mol % 3-propyl-1-heptene, ii) from 7 mol % to 25 mol % 4-ethyl-1-octene, iii) from 24 mol % to 52 mol % 5-methyl-1-nonene, and iv) from 3 mol % to 20 mol % 2-butyl-1-hexene; and 2) less than 10 mol % normal alpha olefin monomer.

9. The process of claim 8 , further comprising:
removing a reaction zone effluent from the reaction zone and optionally contacting the reaction zone effluent with a catalyst system deactivating agent to form a deactivated reaction zone effluent, and
removing at least a portion of the monomer feedstock from the reaction zone effluent or deactivated reaction zone effluent.

10. The process of claim 9 , further comprising:
isolating one or more fractions comprising all or a portion of the olefin oligomers from the reaction zone effluent or deactivated reaction zone effluent, and
hydrogenating at least one of the one or more fractions comprising all or a portion of the olefin oligomers.

11. The process of claim 1 , further comprising removing a reaction zone effluent from the reaction zone and optionally contacting the reaction zone effluent with a catalyst system deactivating agent to form a deactivated reaction zone effluent.

12. The process of claim 11 , further comprising removing at least a portion of the monomer feedstock from the reaction zone effluent or deactivated reaction zone effluent.

13. The process of claim 11 , further comprising isolating one or more fractions comprising all or a portion of the olefin oligomers from the reaction zone effluent or deactivated reaction zone effluent.

14. The process of claim 13 , further comprising hydrogenating at least one of the one or more fractions comprising all or a portion of the olefin oligomers.

15. The process of claim 14 , further comprising isolating one or more fractions from the hydrogenated one or more fractions comprising all or a portion of the olefin oligomers.

16. The process of claim 15 , wherein the at least one of the one or more fractions of the hydrogenated one or more fractions comprising all or a portion of the olefin oligomers has a 100° C. kinematic viscosity of from 1.5 cSt to 12 cSt; or from 15 cSt to 40 cSt.
