===============================================================
Data most important for you, with your limited resources:GAMMA-BUTYROLACTONE :
Physical State: Liquid
Color: colorless
Odor: Mild caramel odor
Boiling Point: 204 - 205 deg C
Freezing/Melting Point: -45 deg C (can be reached with dry ice)
Solubility in water: Miscible.
Specific Gravity/Density: 1.1200g/cm3 (UTFSE with words: Specific Gravity or Density)
2-HYDROXY-GAMMA-BUTYROLACTONE :
Physical State: Liquid
Color: clear, colorless
Boiling Point: 85.0 - 90.0 deg C @ .80mbar
Freezing/Melting Point: 0 deg C
Specific Gravity/Density: 1.313 (Check density compared to gamma-butyrolactone)
You should use TFSE for words : TLC
Then you could perhaps obtain from a reliable source a small sample of gamma-butyrolactone and run 2 TLC's on this sample and compare it to a sample of your find. First boil your sample 30 min to remove that alcohol compound. (but 1000 ppm (parts per million) should not interfere too much, but better be sure to have removed all volatile additions)
Further on, constructing a simple condenser from a glasspipe and a 2x bigger but 10 cm shorter other glasspipe and 2 rubber stoppers with a big hole and a small hole (that one to fit in your water hoses) is childplay. You don't need vacuum. LT/
