Embodiment 1
[0029] Embodiment 1: This embodiment provides a synthesis and purification method of high-purity grade N-isobutoxymethacrylamide IBMA, comprising the following steps:
[0030] S1: Add 350ml of absolute ethanol to a 500ml round bottom flask, add 11g (0.1mol) of tetramethylammonium chloride, 5.2g (0.13mol) of sodium hydroxide, heat and reflux for 4 hours, cool to room temperature, and centrifuge to separate the precipitate , take 200ml of supernatant. Add about 200g of calcined and activated aluminum oxide (α-Al 2 o 3 ), ensure that the aluminum oxide is completely immersed in the solution, and stand at room temperature for 24 hours. The mesoporous alumina was filtered out, and nitrogen was purged at room temperature for 24 hours to dryness to obtain a supported quaternary ammonium base catalyst, which was stored in a vacuum desiccator for future use. The obtained catalyst was recorded as Cat Me 4 NOH / AO.
[0031] S2: In a 500ml round bottom flask, add 120g Cat Me 4 NOH / AO,...
Embodiment 2
[0035] S1: Add 350ml of absolute ethanol to a 500ml round bottom flask, add 15g (0.1mol) of tetrabutylammonium bromide, 11.2g (0.2mol) of potassium hydroxide, heat and reflux for 4 hours, cool to room temperature, and centrifuge to separate the precipitate , take 200ml of supernatant. Add about 200 g of calcined and activated aluminum oxide (α-Al2O3) to the supernatant to ensure that the aluminum oxide is completely immersed in the solution, and stand at room temperature for 24 hours. Mesoporous alumina was filtered out, and room temperature was purged with nitrogen for 24 hours to dryness to obtain a supported quaternary ammonium base catalyst, which was stored in a vacuum desiccator for future use. The obtained catalyst was designated as Cat Bu4NOH / AO.
[0036] S2: In a 500ml round bottom flask, add 150g Cat Bu4NOH / AO, add 170g deionized water, add 4.4g (0.04mol) of hydroquinone, 574g (8mol) of acrylamide and 600g (8.1mol) of isobutanol to the system mol), the temperature o...
