Abstract
CERTAIN substituted hydroxy-derivatives of benzo-y-pyrone (chromone) have been found to give gels of considerable strength when their hot, alkaline solutions (eg, 1 yo in slight excess of aqueous sodium hydroxide) are cooled. This was first observed with the sodium salts of 7- hydroxy-2: 3-diphenylbenzo-y-pyone (I) and 7-hydroxy-3-pheny~-2-s~ yry~ benzo-y-pyrone (11)(Baker and Robinson, J., 1925, 127, 1981*), and later with 5: 7-dihydroxy-3-p-
