| titleOfInvention | Method for producing 2,4-oxazolidinediones |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing 2,4-oxazolidinedione from a metal salt of 2,4-oxazolidinedione in good yield. SOLUTION: 2,4-oxazolidinedione metal salt (III) (Wherein R 1 and R 2 each independently represent a hydrogen atom or a lower alkyl group, and M represents an alkali metal atom), and added to an aqueous solution of an acid to prepare 2,4-oxazolidinediones (IV) To manufacture. Usually, it is produced by adding an aqueous solution of an acid to a solution of a metal salt of a 2,4-oxazolidinedione (III), and the solution is made of a 2-hydroxycarboxylic acid ester (I). , Urea and metal alkoxides (II) Is a reaction mixture obtained by reacting in a solvent. |
