Página 434 - Like the corresponding methyl compound the dichlordiethoxyquinone diethylhemiacetal has acid properties forming with sodic hydrate a sodium salt. It shows toward sodic hydrate a stability in marked contrast to its susceptibility to the action of dilute acids, as it is necessary to boil it with a strong solution of sodic hydrate in order to saponify it to chloranilic acid. The sodium salt of the diethylhemiacetal is white and crystalline, readily soluble in water, slightly soluble in alcohol, and...
