  This disclosure provides a process for making transition metal carboxylate compositions by combining in an polar aprotic first solvent a transition metal precursor and a Group 1 or Group 2 metal carboxylate under substantially acid-free and substantially anhydrous conditions, to generate a mixture comprising the transition metal carboxylate composition. Optionally, the transition metal carboxylate composition can be purified, for example, by substantially removing the first solvent provide a residue comprising the transition metal carboxylate composition, and also optionally, further by extracting the transition metal carboxylate composition from the residue with a non-coordinating second solvent to provide an extract comprising the transition metal carboxylate composition.

  本公开提供了一种制备过渡金属羧酸盐组合物的方法，包括在极性无质子的第一溶剂中，在基本无酸和基本无水的条件下，将过渡金属前体和1组或2组金属羧酸盐组合，生成包含过渡金属羧酸盐组合物的混合物。可选地，可以通过基本去除第一溶剂来提纯过渡金属羧酸盐组合物，得到包含过渡金属羧酸盐组合物的残留物，还可以选择性地通过使用非配位的第二溶剂从残留物中提取过渡金属羧酸盐组合物，得到包含过渡金属羧酸盐组合物的提取物。

  Upon formation of a drug into microspheres by O/W solvent evaporation, a mixed solvent of at least one water-insoluble solvent and at least one water-miscible solvent is used as a solvent of an oil phase. A fatty acid or a salt thereof may be added to the mixed solvent. The oil phase may contain at least one glycerin fatty acid ester and/or at least one propylene glycol fatty acid ester, other than the mixed solvent. The oil phase may also comprise the mixed solvent; a fatty acid or a salt thereof; and at least one glycerin fatty acid ester and/or at least one propylene glycol fatty acid ester. The resulting drug-containing microspheres contain the drug at a high concentration and slowly release from the initial stage after administration.
