Document Type and Number:
Japanese Patent JP2002161085
Kind Code:
A
Abstract:
To provide an industrially advantageous method for producing 5,5- dimethyloxazolidine-2,4-dione; specifically, to provide an industrially advantageous method for producing 5,5-dimethyloxazolidine-2,4-dione by the use of acetone cyanohydrin as the starting material.
This method for producing 5,5-dimethyloxazolidine-2,4-dione is characterized by comprising a reaction between α-hydroxyisobutyramide, a di-lower alkyl carbonate and an alkali metal alcoholate to form a 5,5- dimethyloxazolidine-2,4-dione alkali metal salt followed by neutralizing it with a mineral acid.
