Latest Patents

One of Nagahara's latest patents is a method for producing glycolic acid. This innovative production method involves a two-step process. The first step includes preparing glycolonitrile from formaldehyde and hydrocyanic acid. The second step involves hydrolyzing the glycolonitrile into glycolic acid directly or via a glycolate salt. This method allows for easy production and purification steps while consuming less energy. By carrying out the first and second steps continuously or by storing the glycolonitrile at pH 4 or less, the hydrolysis reaction can be conducted at pH levels ranging from 5 to 9. This approach improves the production yield, activity, and accumulated concentration of glycolic acid, resulting in a product of enhanced purity and quality.
