Determination of the molecular weights of air-sensitive compounds.
A modified Beckmann cryoscopic apparatus is described which is suitable for the measurement of the molecular weights, in solution, of air-sensitive compounds. Results are presented for some aryl compounds of aluminium and of gallium. The accuracy achieved is generally between 1 and 2%.
