<p><P>PROBLEM TO BE SOLVED: To provide a method for decomposing and recovering a vulcanized rubber, the method exhibiting a low reaction temperature and a high energy efficiency and being excellent in reactivity and in recycle recovery of a decomposition reactant. <P>SOLUTION: In the method for decomposing and recovering a vulcanized rubber, divalent iron ion is used as a reaction initiator; a vulcanized rubber including a filler is decomposed by a lipid peroxidation reaction of linoleic acid, or the like; a decomposed rubber component is dissolved in an organic solvent; and the lipid is eliminated by reprecipitating the rubber component in an alcohol including an alkali added thereto, thus recovering the rubber component. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
