权利人:UNIV NORTHEASTERN; CHINNASAMY C N; HARRIS VINCENT G
摘要:A direct chemical synthesis scheme for the fabrication of isotropic and anisotropic rare earth (RE) -transition metal (TM)- based permanent magnets is disclosed. The method according to the invention permits the synthesis of, e.g., particles, films and coatings with controlled particle sizes, shapes, compositions and dispersion in one reaction process. The resulting particles have desirable hard magnetic properties such as high magnetic saturation induction and coercivity at room temperature.

标 题 :Method of recovering in active form the catalyst for the terephthalic acid synthesis
发明人：ROFFIA PAOLO; CALINI PIERANGELO; TONTI SERGIO
权利人:MONTEDISON SPA
摘要:A method of recovering the catalyst in active form from the acetic mother liquors from the synthesis of terephthalic acid. From said mother liquors, after removal of water, there is removed by evaporation an amount of from 70 to 90% of the CH3COOH present therein. The concentrated liquor is cooled below 60 DEG C. and the solid which precipitates is collected and recycled for reuse in the systhesis. The liquid phase is extracted with water or with an aqueous acetic acid solution in the presence of particular coadjuvants such as isobutyl acetate, and the aqueous phase, which contains the recovered catalyst, is recycled to the original synthesis.
