Method for preparing glyoxylic acids and derivatives thereof |
| abstract |
Glyoxylic acids or derivatives thereof are prepared by reacting an acyl nitrile compound with concentrated sulfuric acid in the presence of halide anion to form a first reaction product and then further reacting the first reaction product with a compound of the general formula ROH to form the desired glyoxylic acid or glyoxylic acid derivative. |
