2,4-DIETHOXY-BENZALDEHYDE

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 530 g of acrylonitrile are added dropwise to 890 g (10 mols) of dimethylaminoethanol and 0.3 g of dissolved sodium at room temperature. The mixture is left to stand for 24 hours and low-boiling constituents are distilled off. The mixture is left low-boiling constituents are distilled off

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 244 g of acrylonitrile are added dropwise to 356.5 g of 2-dimethylaminoethanol and 5 ml of Triton B in the course of 15 minutes. In the course of the ensuing exothermic reaction the mixture warms from room temperature to 75° C. While adding a further 5 ml of Triton B, the mixture is heated for 8 hours to 95° C. and then distilled. Yield: 451.4 g (79.4%) of analytically pure product (analysis by gas chromatography); b.p. 102° C./8 torr. In the course of the ensuing exothermic reaction the mixture warms from room temperature to 75° C While adding a further 5 ml of Triton B the mixture is heated for 8 hours to 95° C. distilled
