Alternative solvents for a method of reclaiming styrene and other products from polystyrene based materials |
摘要 |
A method of pretreating polystyrene-containing materials to form a solution of polystyrene in a processing solvent from which the styrene in the polystyrene in the materials is reclaimed. The materials are mixed with an environmentally acceptable pretreating solvent having a lower boiling point than the processing solvent, typically at a location remote from the reclamation plant. The pretreating solvent is selected from the group consisting of d-limonene, l-limonene, dipentene, and blends thereof. Prior to actual processing to reclaim styrene, the pretreating solvent is substantially replaced with the processing solvent. The pretreating solvent may be recovered for reuse.
