Abstract
An improved process for preparing a vinyl-substituted dioxo compound, in which process a vinyl aldehyde is reacted with a compound having three or more hydroxyl groups. In particular, the reaction is carried out, using an acid catalyst, in an organic solvent comprising an aliphatic solvent which forms a binary azeotrope with water as the reaction is driven to completion.
