Abstract

Composition of special fluid comprising at least one hydrogenated mono- and/or at least one polyterpene, in a mixture with at least one special fluid for industrial applications such as the petroleum industry, in construction as sealants and paints, adhesives, the inks industry, metal working, the treatment and protection of metals, but also for domestic uses and in the agric-food and plumbing industries.

First claim

What is claimed is:

1. Composition of special fluid comprising at least one hydrogenated polyterpene selected from the group consisting of hydrogenated sesquiterpenes, and hydrogenated sesterpenes, in a mixture with at least one special fluid, said special fluid being a hydrocarbonated mixture of petroleum or synthetic origin with cut temperatures comprised between 180 and 360° C., the distillation range of which is less than 75° C.

2. Composition according to claim 1 , in which the polyterpenes are selected from the group consisting of farnesane, cyclofarnesane, bisabolane.

3. Composition according to claim 1 , characterized in that the special fluid is obtained by hydrogenation of distillation cuts varying from 180 to 400° C., themselves obtained by hydrocracking, by hydrotreatment, by catalytic cracking, by coking, by vis-breaking and/or by hydrodewaxing, and distillation of said cuts into cuts with a distillation range of less than 75° C., and comprising less than 10 ppm of sulphur and less than 100 ppm of aromatic compounds.

4. Composition according to claim 1 , characterized in that the special fluid originates from the polymerization and/or oligomerization of olefins with 2 to 4 carbon atoms, this polymerization leading to products comprising from 2 to 5 olefin units per chain, and containing paraffins and isoparaffins.

5. Composition according to claim 1 , characterized in that the special fluid is obtained from the conversion of natural gas and/or carbon by conversion to synthesis gas then according to the Fischer-Tropsch process to hydrocarbon compounds capable of being separated after hydrogenation into distillation cuts with cuts comprised between 180 and 400° C. and with a distillation range of less than 75° C., the sulphur content being less than or equal to 10 ppm and the aromatics content less than 100 ppm.

6. Composition according to claim 1 , comprising at least one hydrogenated sesquiterpene selected from the group consisting of farnesane, cyclofarnesane and bisabolane in combination with at least one special fluid with a cut temperature comprised between 230 and 290° C., with a density comprised between 760 and 820 kg/m 3 , and a flash point above 100° C.

7. Composition according to claim 1 , used in the petroleum industry, construction, domestic uses, the automobile, agric-food, pharmaceutical industries, for industrial lubricants, domestic fuels, and applications of fluids permitted for contact with food.

8. Composition according to claim 7 , used in inks, as drilling fluid, for working aluminium or as a cleaning/degreasing agent, said composition comprising hydrogenated sesqui-terpenes.

9. Composition according to claim 7 , used in printing inks, as lubricants, as drilling fluid, in the pharmaceuticals industry, in sealants, in phytosanitary products and for the treatment of textiles and metals, said composition comprising hydrogenated di-terpenes.

10. Composition according to claim 7 , used as lubricants, for the production of pharmaceutical excipients, for the treatment of textiles and metals, and for applications for sealants, said composition comprising at least one hydrogenated di-terpene, in a mixture with at least one special fluid with a cut temperature above 350° C.

11. Composition according to claim 1 , wherein said special fluid is a hydrocarbonated mixture of petroleum or synthetic origin with cut temperatures comprised between 230 and 360° C., the distillation range of which is less than 75° C.

12. Composition according to claim 1 , characterized in that the special fluid is obtained by hydrogenation of distillation cuts varying from 230 to 360° C., themselves obtained by hydrocracking, by hydrotreatment, by catalytic cracking, by coking, by vis-breaking and/or by hydrodewaxing, and distillation of said cuts into cuts with a distillation range of less than 75° C., and comprising less than 10 ppm of sulphur and less than 100 ppm of aromatic compounds.

13. Composition of special fluid comprising at least one hydrogenated diterpene selected from the group consisting of phytane, labdane and pristane, and at least one component selected from the group consisting of hydrogenated monoterpenes, hydrogenated sesquiterpenes, and hydrogenated sesterpenes, the at least one hydrogenated diterpene and the at least one component being in a mixture with at least one special fluid, said special fluid being a hydrocarbonated mixture of petroleum or synthetic origin with a cut temperature greater than or equal to 300° C., with a density comprised between 790 and 840 kg/m 3 , and a flash point above 130° C.

14. Composition according to claim 13 , wherein the hydrocarbonated mixture of petroleum or synthetic origin has a cut temperature comprised between 300 and 350° C., and a density comprised between 800 and 830 kg/m 3 .

15. Composition according to claim 13 , wherein the hydrocarbonated mixture of petroleum or synthetic origin has a cut temperature comprised between 350 and 425° C.

16. Composition according to claim 13 , wherein the hydrocarbonated mixture of petroleum or synthetic origin has density comprised between 800 and 830 kg/m 3 .

17. Composition according to claim 13 , wherein the hydrocarbonated mixture of petroleum or synthetic origin has a viscosity varying from 6.5 to 11 mm 2 /s.

18. Composition according to claim 13 , wherein the composition comprises at least one hydrogenated sesquiterpene selected from the group consisting of farnesane, cyclofarnesane and bisabolane.

19. Composition according to claim 8 , wherein the hydrogenated sesquiterpene is farnesane.
