Embodiment 1
[0033] Add 5 parts of itaconic anhydride and 15 parts of isopropanol into the reactor, start stirring, heat to raise the temperature, control the temperature at 80°C, and react for 1 hour. Add 100 parts of itaconic acid, 0.5 parts of ferrous ammonium sulfate, and 15 parts of water, heat to raise the temperature, control the temperature at 94-96°C, add 25 parts of hydrogen peroxide and 1.5 parts of hydrogen sulfite dissolved in 13 parts of water dropwise The sodium aqueous solution was added dropwise for 4 hours. After the dropwise addition was completed, the reaction temperature was maintained for 1 hour. The reactor is passed cooling water, cooled to a temperature lower than 50°C, and 60 parts of sodium hydroxide aqueous solution dissolved in 60 parts of water is added dropwise to maintain the temperature below 50°C. Crystallization, cooling and crystallization time for 1 hour, and then centrifugal dehydration separation, the isolated itaconic acid-itaconic acid monoisopropan...
Embodiment 2
[0036] Add 10 parts of itaconic anhydride and 15 parts of isopropanol into the reactor, start stirring, heat to raise the temperature, control the temperature at 80° C., and react for 1 hour. Add 100 parts of itaconic acid, 0.5 parts of ferrous ammonium sulfate, and 15 parts of water, heat to raise the temperature, control the temperature at 94-96°C, add 25 parts of hydrogen peroxide and 1.5 parts of hydrogen sulfite dissolved in 13 parts of water dropwise The sodium aqueous solution was added dropwise for 4 hours. After the dropwise addition was completed, the reaction temperature was maintained for 1 hour. Pass cooling water through the reactor, cool down to a temperature lower than 50°C, add 60 parts of sodium hydroxide aqueous solution dissolved in 60 parts of water dropwise, and maintain the temperature below 50°C, pass low-temperature cooling water into the reactor until the temperature is lower than 10°C Crystallization, cooling and crystallization time for 1 hour, and ...
