Abstract

A method of decomposing an organic compound includes decomposing an organic compound by alkyl carbonate at 250° C. or more. The organic compound includes a cross-linked polymer. The cross-linked polymer includes a polymer cross-linked by organic peroxide cross-linking, radiation cross-linking, or silane cross-linking The alkyl carbonate includes dimethyl carbonate or diethyl carbonate.

Claims (11)

1. A method of decomposing an organic compound, comprising:

enclosing the organic compound comprising cross-linked polymer comprising polyolefin resin and alkyl carbonate in a reaction container; and

increasing a temperature in the reaction container to be not less than 250 degrees C., thereby reacting the organic compound and the alkyl carbonate in the reaction container and preferentially decomposing a C—C bond of the organic compound to form a reaction product.

2. The method of decomposing an organic compound according to claim 1 , wherein the cross-linked polymer comprises organic peroxide cross-linked polymer or radiation cross-linked polymer.

3. The method of decomposing an organic compound according to claim 1 , wherein the cross-linked polymer comprises silane cross-linked polymer.

4. The method of decomposing an organic compound according to claim 1 , wherein the alkyl carbonate comprises dimethyl carbonate or diethyl carbonate.

5. The method of decomposing an organic compound according to claim 2 , wherein the alkyl carbonate comprises dimethyl carbonate or diethyl carbonate.

6. The method of decomposing an organic compound according to claim 3 , wherein the alkyl carbonate comprises dimethyl carbonate or diethyl carbonate.

7. The method of decomposing an organic compound according to claim 1 , wherein the polyolefin resin comprises polyethylene.

8. The method of decomposing an organic compound according to claim 1 , wherein the pressure in the reaction container is not less than 1 MPa.

9. The method of decomposing an organic compound according to claim 8 , wherein a gel fraction of the reaction product is less than 50% of a gel fraction of the cross-linked polyethylene before decomposition.
