Chromium(III) (0,0 -diethyl dithiophosphate) forms beautiful flakes which are purple by reflected fight and di-chroic by transmitted fight they are purple at one angle and green at another. The salt is soluble in organic solvents but insoluble in water. It is stable toward air and water, but decomposes at temperatures above its melting point. 

We in vain endeavored to reconvert benzoin into hydrobenzoyl. Fused with hydrate of potassa, it changes like the oil into benzoic acid, with the evolution of hydrogen. But again it differs from the oil, in its behavior with a solution of potassa in alcohol. It is dissolved in the alkaline solution with a purple color, and presently the whole congeals to a mass of fine, foliated crystals. With water these form a milky fluid, firom which by cooling after it has been heated, thick flakes of needle-form crystals are deposited, which are unchanged benzoin.
