1. Add sorbic acid to the reaction kettle, then add 66% water of sorbic acid, add 49% potassium hydroxide solution at 45 ° C until the reaction solution Ph = 8, the reaction takes about 45min. Add a certain amount of activated carbon, vacuum filtration, the filtrate was evaporated under reduced pressure at 40 ~ 45 ℃ 3 ~ 4h to reach the required temperature was raised to 70 ℃ discharge. After centrifugation to crystallize, mother liquor recovery; finally dried at 105 ℃ to give the product.
2. By sorbic acid and potassium hydroxide or potassium carbonate and the dehydration, drying system.
