ABSTRACT:
When a liquid chlorosilane compound inadvertently runs out of a container, the liquid must be disposed by absorbing using an absorbent since chlorosilane compounds are generally very dangerous and toxic. Instead of dry sand conventionally used as an absorbent in such a purpose, the invention purposes that a very efficient effect of absorption can be obtained by using a silica-, silica/alumina-based porous ceramic material or a mixture of them as an absorbent without gas evolution in the liquid and with little temperature increase of the liquid when the absorbent material has a specified content of silica or silica/alumina and a pore diameter distribution.
