DCM for post RP/I2 extraction

[auntyjack]

my chemistry book says the naphtha layer is between 110 and 180 C (consider that toluene boils at 110 C and xylene at 140)....previous posts on naphtha give good info on the various types and their respective boiling point ranges....elfspice, where did you get your info from?

[elfspice]

the terminology of various lower boiling petroleum distillates is perhaps deliberately confusing as it has manifested out of marketing strategies and not standardised nomenclatures etc etc...

I know 'naptha' as a chemical, a dual hexane ring thingy, that is not what i mean, i think it is 'vm&p naptha in some places' which fits the same ranges (40ish to 140ish)

bla bla

here's the local low bp solvent's msds

here's there special purpose plant oil/extraction solvent, a nice hexane fraction

the data stated in the fuelite msds seems to be incorrect from its behaviour in distillation, it started distilling a fraction at about 38 degrees C
