It is larger using difficulty.
Invention content
The technical problem to be solved by the present invention is to provide one kind do not need special installation and special reaction condition, energy consumption compared with
It is low, yield is higher, the preparation method of cellular porous calcium carbonate simple for process and suitable scale industrial production.
The present invention adopts the following technical scheme that solve above-mentioned technical problem, a kind of preparation side of cellular porous calcium carbonate
Method, it is characterised in that the specific steps are：Under normal pressure, soluble carbonate salt particle is dissolved in absolute ethyl alcohol to be configured to paste molten
Liquid, then pasty solutions are filtered with Buchner funnel, saturation calcium salt soln is added after draining in Buchner funnel, then proceedes to take out
Filter adds saturation calcium salt soln and ensures that filter cake is completely immersed in solution, until mouth oozes clarified solution under Buchner funnel during filtering
Saturation calcium salt soln is not added when body, filter cake is rinsed with deionized water and is dried to obtain cellular porous calcium carbonate.
Further preferably, the soluble carbonate salt is one or more in sodium carbonate, potassium carbonate or ammonium carbonate.
