Experimental procedure for determing the vapor pressure of organic liquids at several temperatures through UV absorbance; data and analysis included.

High resolution 1H NMR spectra of two 1,1'-binaphthols (I, II), two 1,1'-binaphthalenediols (III, IV) and four 1,1'- binaphthalenediols acetates (IIIa - IVa) were obtained and analyzed. The effect of the ring current was evaluated by comparing the chemical shifts of the compounds, assigned through H-H COSY NMR experiments, to those of the corresponding monomers. All experimental chemicals shifts are in close agreement with the theoretical values obtained via the Bovey model for the ring current effect of a benzene moiety.

Since most current undergraduate organic labs use both micro and macro scale experiments, the availability of different size heating mantles become necessary. This article suggests a way around the potential problems, especially among third world countries where heating mantles are expensive.
