Abstract

Alkali metal bisulphite adducts of succinaldehyde are prepared by reacting an aqueous solution of a 2,5-dialkoxy- or 2,5-diacyloxy-tetrahydrofuran with an alkali metal bisulphite. The reaction is advantageously carried out at an elevated temperature, e.g. about 100 DEG C., for preferably 80-100 DEG C., for about 6-12 hours. The product separates as a bis-alkali metal bisulphite dihydrate and may be recrystallised from an aqueous alkanol. Tropanone is prepared by reacting succinaldehyde bis-sodium bisulphate dihydrate, acetone dicarboxylic acid and methylamine hydrochloride in aqueous solution for 3 days at room temperature.
