Hi i dont have time to go into detail right now but id just like to put forward an idea i have about separating plastic from ic chips.
Its pure speculation and somewhat vague but if theres something suitable available youll be happy for it.
Whats the MP and does anyone know exactly the composition of the plastic coating the ic chips?
How about heat the chips in the high bp 'oil' and with a bit of luck your plastic floats up and your denser materials sink.
In a perfect scenario the plastics have separated and can be removed. They wont have pyrolised or incinerated and no toxic fumes given off.
Your left with a skeletised defleshed ic chip ready for another process.
I will try my best in the coming days to find a particular document relating to series of high boiling relatively inert chemically dense liquids and post it for scrutiny and possibility.. in the meantime someone might find it first and expand on the idea
I think im in error i was thinking of higher alkanes and paraffins or waxes even perhaps silicon oil but theyll react with the plastic acting as a solvent. They may well still separate from the chip but then youd have to distill to the mess afterwards to recover the solvent
Would it be feasable to crack a batch of plastic chip material with pyrolysis and use the alkanes distilled in subsequent batches to dissolve ic chips conveniently though?
Sorry if its a pointless post
