Abstract

PURPOSE: To provide powdered liq.-holding silica having an org. Si halide compound in the bonded form and maintaining the powdered state even after containing a soln. in large quantities.
CONSTITUTION: An org. Si halide compound such as trimethylmonochlorosilane and silicic acid hydrate are reacted at a temp. at which the condensation of the surface silanol group does not occur, e.g. at 300W400°C. They may be reacted in the presence of an org. solvent such as alcohol miscible with water. Thus, powdered liq.-holding silica having the org. Si halide compound in the bonded form is obtd. This silica shows ≥125°, preferably ≥about 140° contact angle to water, has ≤15μ, especially ≤5μ average particle size, and holds ≥1cc/g soln. Accordingly, mineral acid or the like attended with danger in transportation can be carried in the state of powder.
