Oh my formatting kind of got messed up, but the number under each
volume value is the refractive index of that sample. The temperatures
are lined up fine.

Hi all,
I performed a fractional distillation with glass beads on n-propyl
acetate.

Sample # BP Range Refractive Index
1 57-54 1.363
2 54-51 1.364
3 50-55 1.362
4 55-58 1.363
5 58-89 1.369
6 89-117 1.382

Temperature dropped while collecting the first two samples because
heat was turned down
significantly after the 3mL portions started collecting too fast. The
sample boiled over at
the end and dropped to 51C after sample 6, which was only about 2mL.
