Manufacture of calcium carbonate dispersions in ...

Calcium oxide and carbon dioxide were allowed to react in an organic liquid in the presence of dispersing agents. Calcium carbonate was produced in a finely divided form. Carbonation did not occur unless small quantities of chloride ion were present. The size of the carbonate particles depended on the nature of the cation in the chloride additive and the amount of methanol present. Other ...
