*The furfural film prepared on 10/31/2012 followed the general protocol for rinsing of fufural films. | |||
*The fufural film was spin in EtAc for 2.5hours | |||
'''Observations''': | |||
*Before placement in the ethyl acetate, the film was a dark brown color(uniformly distributed throughout the film) and was very rigid. So rigid slight cracking appeared to be occurring toward the edge of the film | |||
*While in the ethyl acetate, approximately 2 hours into the stirring, slight leakage of furfural from the film. Very slight(perhaps no leakage at all). Some of the ethyl acetate solution was placed in a falcon tube for later analysis. | |||
*After 2.5hrs in the ethyl acetate, film was still dark brown colored and extremely rigid | |||
