| titleOfInvention | Method for producing glycolic acid |
| abstract | By obtaining glycolonitrile from formaldehyde and hydrocyanic acid as the first step and hydrolyzing the glycolonitrile directly as the second step to produce glycolic acid, or by producing glycolic acid via glycolate, Provided is a glycolic acid production method with a low energy consumption and a simple production process and purification process. In this production method, the first step to the second step are carried out as a continuous step, or the glycolonitrile obtained in the first step is stored at a pH of 4 or less, and the second step By performing the decomposition reaction at a pH of 5 to 9, the yield of glycolic acid, the activity of glycolic acid production, the accumulated concentration of glycolic acid are improved, and the purity and quality of the resulting glycolic acid are improved. |
