- COCONDENSATION OF ISOBUTYLENE WITH FORMALDEHYDE AND ACETALDEHYDE
-
2,4,4-Trimethyl-1,3-dioxane is formed preferentially in the reaction of isobutylene, formaldehyde, and acetaldehyde in the presence of an acidic catalyst.In addition, 4-dimethyl- and 2,4,4,6-tetramethyl-1,3-dioxanes, 4-methyl-2,4-pentanediol and 3-methyl-1,3-butanediol were found in the reaction mass.The possibility of mutual transformations between the cyclic acetals and formal through the stage of the formation of consecutive-parallel reactions is proposed.
