Abstract
Natural and synthetic rubber can be reclaimed by the use of a reclaiming oil having a molecular weight between 200 and 1000 and comprised of a mixture of substituted benzene compounds, such as alkyl benzenes and alkylated indanes, which mixture has an initial boiling point greater than or equal to 240.degree. C. These may be the only reclaiming oils charged to the digester, or they may be used to replace any volatile reclaiming oils used in the older processes. The resulting reclaimed rubber gives no greater contact or migratory stain then reclaimed rubber made with known non-staining oils, and much less oil is lost during the venting or blow-down of the digester.
