Abstract
DURING attempts to prepare samples of β-quinol by the method of Powell and Riesz1, we observed that the crystals obtained, which gave X-ray powder-photographs characteristic of β-quinol, effervesced when dissolved in water. When 1 gm. of a sample of this substance which had been dried in vacuo was dissolved in water, 7.9 c.c. (at N.T.P.) of a gas were evolved. This gas contained 28 per cent oxygen, and the rest appeared to be nitrogen. It therefore seems probable that this is an ‘air’ clathrate2 compound of β-quinol in which about 12 per cent of the available spaces are filled.
