Abstract
Provided are a liquid hydrocarbon production method for obtaining a liquid hydrocarbon-containing rubber composition, including heating a crosslinked rubber at 300° C. or lower in a reaction solvent that contains an aldehyde having a hydrocarbon group with 2 or more carbon atoms and having a boiling point of 230° C. or lower; as well as a re-crosslinked rubber obtained from the rubber composition produced in the production method, and a tire and a rubber industrial product. According to the liquid hydrocarbon production method, a liquid hydrocarbon having a higher molecular weight can be produced at a high decomposition proportion even under mild conditions.
