1.50g of 1,4-dimethoxybenzene DL-3-methyl-2-butanol was used as the alcohol observations: mixture

My data was not very useful since no dots showed up at all. My column was most likely dried due to a

I did a fractional distillation using choreboy. Methyl Acetate with n- propyl acetate. Sample Temp.

PART A: % recovery= 70.0% Started melting= 97.1 degrees C Finished Melting= 102.0 degrees C PART B,

Initial mass (g) Final mass (g) Percent Recovery Melting Point Trial 1 1.00 1.78 178% 123.8°C Trial 2

Part A: % recovery: 99% MP range: 112-120 C Part B (variation #1, identical to Part A) % recovery:

Trial 1: Recovery: 87% Melting Point Range: 102.1-113.3 Trial 2: Variation A (everything the same)

Part A: % recovery: 48% started melting at 116.3 degrees C finished melting at 123.6 degrees C Part B
