Reaction Steps

A mixture of 100 parts of 3,3-dimethylacrolein, 200 parts of prenol and 150 parts of propionic acid is heated for three hours at 130° C., the water formed being distilled out azeotropically. The reaction product is worked up. 24 parts of citral is obtained. This is equivalent to yield of 51% of theory at a conversion of 26% (based on 3,3-dimethylacrolein).
