| titleOfInvention | Method for producing α-oxocarboxylic acid ester |
| abstract | (57) [Summary] [Invention] α-oxocarboxylate is produced inexpensively and efficiently in a substantially single step using inexpensive 1,2-diol such as ethylene glycol or propylene glycol as a raw material. A manufacturing method is provided. SOLUTION: 1,2-Diol is vapor-phase oxidized in a first-stage reactor 7 to form gaseous α-oxoaldehyde and / or α-oxoaldehyde. -After obtaining hydroxyaldehyde, this gaseous α- The alcohol or olefin gasified in the vaporization chamber 14 is added to oxoaldehyde and / or α-hydroxyaldehyde, and the mixture is introduced into the second reactor 11. Oxidative esterification with molecular oxygen in the presence of a catalyst in to produce an α-oxocarboxylic acid ester. |
