Title: Process for the manufacture of polyhydric alcohols
Filed: 1959-12-15
Abstract: Polyhydric alcohols are produced continuously by the aldol condensation of formaldehyde with a higher aldehyde in an aqueous medium in the presence of an alkaline condensing agent followed by the Cannizzaro reaction, in a first stage of which the aldehydes and the alkaline condensing agent are continuously introduced into one or more reaction vessels in series through which the reactants are passed continuously while subjected to "back-mixing" with 40-90% of the proportion of formaldehyde necessary for the aldol reaction has reacted, and in a second stage of which the resulting mixture is passed through one or more reaction vessels in series in which the mixture is further reacted without being subjected to "back-mixing" so that all parts of the mixture have substantially equal residence times in the vessel or vessels.  The term "back-mixing" is used to signify that parts of the reaction mixture that are of different ages, i.e. have spent different periods in the reactor, mix with each other.  The first stage is preferably carried out at 0-60 DEG C. and the second at 15-55 DEG C. Suitable higher aldehydes are, for acetaldehyde, propionaldehyde, butyraldehyde, and isobutyraldehyde. When acetaldehyde is used the product is a mixture of pentaerythritol, dipentaerythritol and polypentaerythritols. Suitable alkaline condensing agents and, for example, calcium or barium hydroxide, caustic soda, caustic potash, sodium carbonate, potassium carbonate and trimethyl-ammonium hydroxide.
