Pyrobitumen is a type of solid, amorphous organic matter. Pyrobitumen is mostly insoluble in carbon disulfide and other organic solvents as a result of molecular cross-linking, which renders previously soluble organic matter (i.e., bitumen) insoluble. Not all solid bitumens are pyrobitumens, in that some solid bitumens (e.g., gilsonite) are soluble in common organic solvents, including CS
2, dichloromethane, and benzene-methanol mixtures.
