A kind of preparation method of acetic acid and the order mesoporous catalyst of formaldehyde acrylic acid synthesizing

The invention discloses the preparation methods of a kind of acetic acid and the order mesoporous catalyst of formaldehyde acrylic acid synthesizing, including following preparation process：Using hydrothermal synthesis method synthesizing ordered mesoporous molecular sieve SBA 15；Sodium salt, boric acid and soluble in water be uniformly mixed of auxiliary agent are obtained into presoma maceration extract；Carrier S BA 15 is added in presoma maceration extract and is impregnated, mixed liquor is evaporated in a water bath, in dry in baking oven；Order mesoporous catalyst is obtained after finally roasting 2 ~ 8h at 400 ~ 600 DEG C in Muffle furnace.In catalyst preparation process of the present invention, it is not directed to hypertoxic class hazardous agents or organic solvent, condition is easily-controllable；Raw material is generally easy to get, and production cost is low, is suitble to large-scale industrial production；Catalyst prepared by the present invention is since its mesoporous orderly duct is flourishing, and soda acid bimetallic active object is high to aldol reaction catalyst activity, and selectivity is good, and catalyst stabilization performance is good.
