Claims
- 1. A process for the production of ester product from a mixture of near linear mono-olefinic oligomers having six to twenty carbon atoms, wherein at least 20 weight percent of the mono-olefin oligomers comprise at least twelve carbon atoms having an average of 0.80 to 2.0 methyl side groups per carbon chain, said oligomer containing internal olefinic unsaturation, comprising;
- reacting said oligomer with H.sub.2 and CO mixture in contact with a hydroformylation catalyst under hydroformylation conditions sufficient to convert said oligomer to aliphatic 1-alkanol, said alkanol having a methyl to methylene branch ratio equal to or less than said oligomer; and
- converting said 1-alkanol to an ester under esterification conditions in contact with aliphatic acylating agent.
- 2. The process of claim 1 wherein said oligomer comprises the oligomerization product of C.sub.3 -C.sub.5 alkene in contact with surface deactivated, acidic, shape selective, medium pore metallosilicate.
- 3. The process of claim 2 wherein said oligomer comprises the oligomeration product of propylene.
- 4. The process of claim 1 wherein said oligomer has a methyl to methylene branch ratio less than 0.25.
- 5. The process of claim 4 wherein said ratio is about 0.1 to 0.2.
- 6. The process of claim 1 wherein said oligomer comprises C.sub.9 -C.sub.12 hydrocarbon having methyl to methylene branch ratio of less than 0.18.
- 7. The process of claim 1 wherein said hydroformylation catalyst comprises rhodium, cobalt or ruthenium.
- 8. The process of claim 1 wherein said hydroformylation catalyst consists essentially of Co.sub.2 (CO).sub.6 [(n-C.sub.4 H.sub.9).sub.3 P].sub.2.
- 9. The process of claim 1 wherein the H.sub.2 /CO ratio is about 0.5:1 to 5:1.
- 10. The process of claim 9 wherein said ratio is about 1.8 to 1.
- 11. The process of claim 1 wherein said hydroformylation conditions comprise reaction temperature of about 150.degree. to 250.degree. C.
- 12. The process of claim 11 wherein hydroformylation temperature is about 181.degree. C.
- 13. The process of claim 1 wherein said acylating agent comprises aliphatic carboxylic acid, anhydride, halide or ester having 2 to 20 carbon atoms.
- 14. The process of claim 1 wherein said acylating agent comprises acetic anhydride and said ester comprises acetate.
