production method | is obtained by neutralizing tartaric acid with potassium hydroxide and sodium hydroxide. In a reaction pot equipped with a stirring and steam heating tube, Solid alkali and liquid potassium hydroxide were added, and water was added to dissolve. Tartaric acid was added with heating and stirring until the pH of the solution was 7. Hot Suction filtration, the filtrate was put into the crystallization Pan, cooling crystallization. After Suction filtration, the chloride is removed by washing with water, and the product is obtained after boiling and drying below 48 °c. |
