    摘要: In the beneficiation of phosphate ore by the flotation of siliceous material, the utilization of a condensate of N-aminoethylpiperazine with a fatty acid or fatty acid ester improves the separation of phosphate from silica. This improvement is especially great in the presence of a co-collector consisting of a polyethylenepolyamine condensed with a fatty acid.

    摘要: An epoxy resin adduct including the reaction product of (A) at least one polyfunctional aliphatic or cycloaliphatic epoxy resin; and (B) at least one reactive compound; wherein the polyfunctional aliphatic or cycloaliphatic epoxy resin is isolated from the epoxy resin formed by the epoxidation of (i) an aliphatic or cycloaliphatic hydroxyl-containing material using (ii) an epi-halohydrin, (iii) a basic-acting substance, (iv) a non-Lewis acid catalyst, and (v) optionally one or more solvents; and wherein the re-active compound (B) comprises one or more compounds having two or more reactive hydrogen atoms per molecule and the reactive hydrogen atoms are reactive with epoxide groups. A curable epoxy resin composition includes the adduct described above. A cured epoxy resin is prepared by a process of curing the curable epoxy resin composition containing the adduct described above.
