Abstract
Process for the manufacture of an adipic acid product by a reduction of a tetrahydrofuran dicarboxylic acid compound, wherein the tetrahydrofuran dicarboxylic acid compound is contacted with hydrogen iodide at a temperature of at least 100° C. in an inert atmosphere to yield the adipic acid product.
Claims16
A method for the manufacture of an adipic acid product by a reduction of a tetrahydrofuran dicarboxylic acid compound, wherein the tetrahydrofuran dicarboxylic acid compound is tetrahydrofuran dicarboxylic acid, a hydrocarbyl ester of such acid, a metal salt of such acid or a combination thereof, wherein the tetrahydrofuran dicarboxylic acid compound is contacted with hydrogen iodide at a temperature of at least 100° C. in an inert atmosphere to yield the adipic acid product.
A method for the preparation of an adipic acid product, wherein a carbohydrate-containing biomass starting material is converted in the presence of an acid catalyst to a 5-hydroxymethyl furfural compound, wherein the 5-hydroxymethyl furfural compound is oxidized to a furandicarboxylic acid compound,
- wherein the furandicarboxylic acid compound is hydrogenated to obtain a tetrahydrofuran dicarboxylic acid compound, wherein the tetrahydrofuran dicarboxylic acid compound is tetrahydrofuran dicarboxylic acid, a hydrocarbyl ester of such acid, a metal salt of such acid or a combination thereof;
- and
- wherein the tetrahydrofuran dicarboxylic acid compound is contacted with a hydrogen iodide in an inert atmosphere, at a temperature of at least 100° C., to obtain the adipic acid product.
