Product 1

HCID 23624071Dipotassium D-glucarate

Procedure

The oxidation of D-glucose was carried out as in Examples 1 and 2. However, potassium hydroxide was substituted for sodium hydroxide in the neutralization process to give crude D-glucaric acid dipotassium salt (151.25 g, 70.4% based on pure dipotassium D-glucarate). The salt was precipitated from methanol as described to give an off white solid (145.75 g, 67.9% based on pure dipotassium D-glucarate).

Workup

  1. customto give crude D-glucaric acid dipotassium salt (151.25 g, 70.4% based on pure dipotassium D-glucarate)
  2. customThe salt was precipitated from methanol
