Abstract

1,190,536. Treating lime. RHEINISCHE KALKSTEINWERKE G.m.b.H. 18 July, 1968 [22 July, 1967], No. 34198/68. Heading C1A. Powdered calcined CaO is treated during or after grinding with an amine salt to prevent agglomeration. The amine may be aliphatic, cycloaliphatic, or aromatic, with 6-22 carbon atoms. The acid used to form the salt may be inorganic, e.g. HCI, or an aliphatic, cycloaliphatic or aromatic organic acid having 2-9 carbon atoms. Preferred salts are the formates, acetates, caproates, and benzoates of triethylamine, cyclohexyl amine, primary amines with 8-22 carbon atoms, aniline, and α-naphthylamine. The amount of salt used may be 0À01- 0À5% by wt., and may be added in aqueous solution such as to provide 0À1-1% H 2 O.
