Tuesday Lab
"Crystals grown today" wt tube 171.18 g , wt tube + amine 176.39 g, observed rotation -4.0°, tubelength = 0.45 dm
"Crystals grown over week" wt tube 195.54 g , wt tube + amine 200.15 g, observed rotation -6.0°, tubelength = 0.45 dm
The total volume of the solutions was 14.5 mL.
Proton NMR of product:
"sec02 LP EK RL crystals amine h1-1.jdf" (large crystals but chiral resolution agent did not work, I do not know what was done wrong)
"sec02 666 amine h1-1.jdf" (fast crystals and chiral resolution agent worked. Separate doublets for the two enantiomers are seen)
