摘要:a) The present invention falls within the area of the synthesis of ionic liquids, namely it concerns a process of synthesis of the ionic liquid tetraoctylammonium di(2-ethylhexyl)-oxamate (IL-5) with a high degree of purity and its use in the extraction and selective separation of metals, namely lanthanides. Thus, it is the object of the present invention, a process for the synthesis of a pure ionic liquid using in its constitution only the elements carbon, hydrogen, oxygen and nitrogen (CHON), assuming itself as a “greenâ€? alternative in the recovery of metals, thus reducing the environmental impact in the way they are recovered, as well as the guarantee of a more efficient extraction of these metals.

摘要:Methods for synthesis of hierarchically ordered zeolites and zeolite-type materials are provided. Synthesized hierarchically ordered zeolites and zeolite-type materials formed according to the methods herein possess a high-degree of well-defined long-range mesoporous ordering. The methods include base-mediated reassembly, by dissolution of the parent material to the level of oligomeric structural building units of the parent material, and minimizing or avoiding amorphization/structural collapse. The dissolution and self-assembly is comprehensively controlled to produce hierarchically ordered zeolites and zeolite-type materials according to the methods herein.

摘要:The invention relates to an improved process for preparing 2-(1-benzylpiperidin-4-ylmethyliden)-5,6-dimethoxyin-dan- 1 -one (a key intermediate in the synthesis of donepezil hydrochloride), crystalline polymorph forms of this key intermediate and their use thereof for producing donepezil hydrochloride. In particular, the invention provides an improved method for producing the intermediate 2-(1-benzylpiperidin-4-ylmethyliden)-5,6-dimethoxyindan-1-one. The process includes reacting 5,6-dimethoxyin-dan- 1 -one with 1-benzylpiperidine-4-carbaldehyde using potassium hydroxide in an aqueous solvent. The aqueous solvent can be a mixture of an organic solvent and water Where the organic solvent is not miscible with water, the reaction may be performed in the presence of a phase transfer catalyst.
