YieldReaction ConditionsOperation in experiment
97.8% With hydrogenated D001 type strong acid cation exchange resin at 115℃; for 4h; 1-4 Example 2 The purchased sodium type D001 macroporous strong acid cation exchange resin was washed with absolute ethanol and deionized water, and then immersed in a solution having a hydrochloric acid concentration of 5% for 8 hours. Weigh 13.01 g of itaconic acid and 25.942 g of n-butanol.Add to a three-necked flask with a water separator and thermometer.Magnetic stirring and heating up,After all the itaconic acid was dissolved, 1.301 g of hydrogenated D001 type strong acid cation exchange resin was weighed into a three-necked bottle.After heating to 115 ° C, start timing and react for 4 hours.Obtaining a crude product of di-n-butyl itaconate;The subsequent purification process is the same as in the first embodiment.The finished product of di-n-butanic acid was obtained in a yield of 97.8%.
95.02% With La3+SO42-/TiO2-SiO2 for 3.5h; Esterification of itaconic acid with 1-butanol, 2-isooctanol General procedure: A mixture of itaconic acid, 1-butanol, 2-isooctanol and catalyst were put into a 100 mL three-neck flask equipped with a reflex condenser under continuous stirring. Various parameters, such as the molar ratio of 1-butanol, 2-isooctanol to itaconic acid, amount of catalyst and reaction time were varied to optimize the reaction conditions. After the reaction, catalyst was separated by filtering. Reaction equation was shown in Scheme 1

YieldReaction ConditionsOperation in experiment
With hierarchical mesoporous zeolites at 100℃; for 6h; Overall yield = 95.2 %; chemoselective reaction; 2.4 Catalytic reactions Before esterification, all the catalysts were ion exchanged with 1 M NH4NO3 for three times and calcined to convert the zeolites into H+ form. In a typical reaction, 0.1 mol itaconic acid (13 g) and 0.3 mol n-butyl alcohol (22.23 g) with 2 g decane as internal standard were added into the three-neck flask equipped with a reflux condenser. When the temperature was stabilized at 100 °C, 0.26 g catalysts after drying at 150 °C for 2 h to eliminate adsorbed water were added into the reacting system. The samples were periodically taken and analyzed by GC-MS (Agilent, 6890/5973 N). The yields of monobutyl itaconate and dibutyl itaconate were given by drawing a standard curve by using decane as internal standard to determine the concentration of corresponding substances. In recycling tests, hierarchical porous zeolites (HMZ and HNZ) and traditional ZSM-5 zeolites were separated from reaction system, dried at 100 °C for 2 h, and then added to fresh substrate solution. The reaction time duration was limited to 6 h according to the catalytic activity shown in the first catalytic experiment. After three recycles, catalysts were calcined at 550 °C for 6 h to eliminate the coke deposition and then reused to investigate the catalytic activity.
