Abstract

6216. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. March 14. Ketones, compounds of. Stable compounds are obtained by the combination of hyposulphites with ketones, such as acetone or methyl-ethyl ketone, in presence of alkalies. An example is given in which to sodium hyposulphite solution are'added acetone, caustic soda lye, and ammonia solution. The resulting solution reduces indigo-sulphonic acid slowly in the cold. Evaporation in vacuo gives a stable solid compound.
