Chloroacetaldehyde → HCID 12207149, compound

Participants

Reaction Steps

To 100.12 g acetylacetone, 44 g dolomite powder and 4 ml pyridine (5 mol%) are added as described in example 1, whereafter 174.4 g 45% aqueous chloracetaldehyde solution is added, with stirring. Stirring is continued at 70° C. for 4.5 hours, and then another hour at 75° C. The CO2 -volume generated is 10.8 liter at room temperature. Workup occurs as in example 1. A fraction is collected at temperatures from 59°-61° C. at 11 torr; it amounts to 93.56 corresponding to 75.5% of the theoretical.
