Embodiment 1
[0048] A preparation method of ZSM-5 molecular sieve filled silicone rubber / cellulose acetate composite membrane, the method may further comprise the steps:
[0049] (1) Weigh 0.25g of ZSM-5 molecular sieve, put it into a muffle furnace and roast at 300°C for 3h, add 8ml (7.2g) of ethyl acetate, and ultrasonically disperse for 1h to obtain a molecular sieve dispersion;
[0050] (2) Weigh 5g of silicone rubber and put it into a beaker, then add 8ml (7.2g) of ethyl acetate, then stir magnetically until it is completely dissolved, add molecular sieve dispersion, and then add 0.25g of crosslinking agent tetraethyl orthosilicate, After magnetically stirring for 1 hour, add 0.2 g catalyst organotin and stir for 10 minutes to obtain a casting solution;
[0051] (3) Soak the cellulose acetate (CA) supporting film in clean water to make it fully wetted and saturated;
[0052] (4) Fix the wetted CA support film on a glass plate, wipe off the surface water, pour the casting solution eve...
Embodiment 2
[0057] Using the same process steps as in Example 1, only changing the amount of ZSM-5 molecular sieve to 0.1g, the performance of the obtained composite membrane pervaporation separation of acetaldehyde solution is: permeation flux 149.3g / m 2 h, separation factor 7.2.
Embodiment 3
[0059] Using the same process steps as in Example 1, only changing the amount of zsm-5 molecular sieve to 0.4g, the performance of the obtained composite membrane for pervaporation of acetaldehyde aqueous solution is: permeation flux 96.4g / m 2 h, separation factor 5.0.
