Superior Solvents and Chemicals

P2 Techies-

I thought I had circulated this subject before, but have had no response:

I am working with boat manufacturers who commonly use both "SuperBlue" and
"S280" (Superior brand) for resin and gelcoat cleaning.  They are either
managed separately as wastes or as a mixed stream.  Do any of you know some
reclamation processes or distillation capabilities for these?  They are
composed as follows:
SuperBlue LF Resin Cleaner
diproplyene glycol methy ether  1-5%
Boiling Point  212 degrees F
Specific Gravity  1.07
Vapor Pressure  17.5 mm Hg 
Water Solubility  100%

S280 Super Flush
dimethyl glutarate                    29%
oxybispropanolmethylether           9%
dimethyl adipate                          9%
dimethyl succinate                        9%
Boiling Point  368 degrees F
Specific Gravity  1.064
Vapor Pressure  0.0119 psi
Water Solubility 23.987% 

Often the S280 is often contaminated with acetone, which is used for drying.

All help muchly appreciated...
