Title Polycyclic aromatic carbon based solid strong acid achieved
Abstract (US7335790)
A composite solid strong acid comprising, a solid acid and a carbon material, wherein said solid acid is obtained by heat treating of polycyclic aromatic hydrocarbons or polycyclic aromatic hydrocarbons to which the carbon material is blended in concentrated sulfuric acid or fuming sulfuric acid, transforming said polycyclic aromatic hydrocarbons to a solid acid which is insoluble in a polar solvent by condensation and sulfonation further compositing with said carbon material.
Scope of claims [claim1]
1. A solid acid, which is insoluble in a polar solvent, obtained by heat treating of polycyclic aromatic hydrocarbons in concentrated sulfuric acid or fuming sulfuric acid to thereby condense and sulfonate said polycyclic aromatic hydrocarbons wherein temperature T for heat treatment is 200 deg. C. <= T <= 450 deg. C.
[claim2]
2. The solid acid of claim 1, wherein polycyclic aromatic hydrocarbons is at least one selected from the group consisting of a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings, mixture of a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings or tar, pitch, fuel oil or asphalt containing a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings.
[claim3]
3. The solid acid of claim 2, wherein temperature T for heat treatment is 200 deg. C. <= T <= 350 deg. C.
[claim4]
4. A solid strong acid catalyst comprising, a solid acid, which is insoluble in a polar solvent, obtained by heat treating of polycyclic aromatic hydrocarbons in concentrated sulfuric acid or fuming sulfuric acid to thereby to concentrate and sulfonate said polycyclic aromatic hydrocarbons wherein temperature T for heat treatment is 200 deg. C. <= T <= 450 deg. C.
[claim5]
5. The solid strong acid catalyst of claim 4, wherein polycyclic aromatic hydrocarbons is at least one selected from the group consisting of a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings, mixture of a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings or tar, pitch, fuel oil or asphalt containing a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings.
[claim6]
6. The solid strong acid catalyst of claim 5, wherein temperature T for heat treatment is 200 deg. C. <= T <= 350 deg. C.
[claim7]
7. A composite solid strong acid comprising, a solid acid and a carbon material, wherein said solid acid is obtained by heat treating of polycyclic aromatic hydrocarbons to which the carbon material is blended in concentrated sulfuric acid or fuming sulfuric acid, transforming said polycyclic aromatic hydrocarbons to a solid acid which is insoluble in a polar solvent by condensation and sulfonation further compositing with said carbon material wherein temperature T for heat treatment is 200 deg. C. <= T <= 450 deg. C.
[claim8]
8. The composite solid strong acid of claim 7, wherein polycyclic aromatic hydrocarbons is at least one selected from the group consisting of a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings, mixture of a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings or tar, pitch, fuel oil or asphalt containing a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings.
[claim9]
9. The composite solid strong acid of claim 8, wherein temperature T for heat treatment is 200 deg. C. <= T <= 350 deg. C.
[claim10]
10. The composite solid strong acid according to claim 7, wherein the carbon material is at least one selected from the group consisting of carbon black, acetylene black, activated carbon, carbon nano tube or fullerene.
[claim11]
11. The solid acid of claim 10, wherein temperature T for heat treatment is 200 deg. C. <= T <= 350 deg. C.
[claim12]
12. The composite solid strong acid according to claim 8, wherein the carbon material is at least one selected from the group consisting of carbon black, acetylene black, activated carbon, carbon nano tube or fullerene.
[claim13]
13. The composite solid strong acid according to claim 9, wherein the carbon material is at least one selected from the group consisting of carbon black, acetylene black, activated carbon, carbon nano tube or fullerene.
[claim14]
14. A composite solid strong acid comprising, a solid acid and a carbon material, wherein said solid acid is obtained by heat treating of polycyclic aromatic hydrocarbons to which the carbon material is blended in concentrated sulfuric acid or fuming sulfuric acid, transforming said polycyclic aromatic hydrocarbons to a solid acid which is insoluble in a polar solvent by condensation and sulfonation further compositing with said carbon material, wherein the carbon material is at least one selected from the group consisting of carbon black, acetylene black, activated carbon, carbon nano tube or fullerene.
[claim15]
15. The composite solid strong acid of claim 14, wherein polycyclic aromatic hydrocarbons is at least one selected from the group consisting of a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings, mixture of a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings or tar, pitch, fuel oil or asphalt containing a polycyclic aromatic hydrocarbon obtained by condensing two or more aromatic rings, wherein the carbon material is at least one selected from the group consisting of carbon black, acetylene black, activated carbon, carbon nano tube or fullerene.
[claim16]
16. The composite solid strong acid of claim 14, wherein temperature T for heat treatment is 100 deg. C. <= T <= 450 deg. C., wherein the carbon material is at least one selected from the group consisting of carbon black, acetylene black, activated carbon, carbon nano tube or fullerene.
[claim17]
17. The composite solid strong acid of claim 14, wherein temperature T for heat treatment is 200 deg. C. <= T <= 350 deg. C., wherein the carbon material is at least one selected from the group consisting of carbon black, acetylene black, activated carbon, carbon nano tube or fullerene.
