| titleOfInvention | Method for producing α, β-unsaturated carboxylic acid |
| abstract | PROBLEM TO BE SOLVED: To provide an industrially advantageous method for producing an α, β-unsaturated carboxylic acid (for example, acrylic acid, methacrylic acid, etc.). SOLUTION: Expression (1) (In the formula, R represents a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, an alkenyl group, or an alkynyl group.) Wherein a carboxylic acid represented by the formula (1) is reacted with formaldehyde or a formaldehyde precursor in the presence of a metal sulfate. (In the formula, R represents the same meaning as described above.) A method for producing an α, β-unsaturated carboxylic acid represented by the formula: [Selection diagram] None |
