标题:一种工业生产5-一硝酸异山梨酯的改进工艺:废物回收
摘要:研究了不同的方案以回收工业生产5一硝酸异山梨酯(is-5-Mn)中产生的废物.对于废水,通过利用其碱性环境将异山梨醇-2-一硝酸酯(is-2-Mn)水解为原料异山梨醇(is)来实现处置,其中naoac也以三水合物的形式有效地回收了.对于固体废物,研究了两种不同的方案:直接结晶和催化氢化.前者有效地提供了有用的硝酸异山梨酯(isdn),而后者则提供了一种有效且可扩展的路线,可以从isdn合成is-5-Mn.单位操作的组合以100千克规模进行了评估,并被证明是可行且可靠的.

摘要:Novel methods of synthesis of chelator-targeting ligand conjugates, compositions comprising such conjugates, and therapeutic and diagnostic applications of such conjugates are disclosed. The compositions include chelator-targeting ligand conjugates optionally chelated to one or more metal ions. Methods of synthesizing these compositions in high purity are also presented. Also disclosed are methods of imaging, treating and diagnosing disease in a subject using these novel compositions, such as methods of imaging a tumor within a subject and methods of diagnosing myocardial ischemia.

摘要:Isosorbide-5-methacrylate was obtained by enzymatic catalysis with Lipozyme RM IM in a highly regioselective manner in up to 87% yield. The process uses readily available acyl donors (methacrylic anydride or vinyl methacrylate), is easily scalable and chromatography free. Simple extractive workup followed by decoloration and filtration affords the monomer with up to > 99% purity. In addition, the developed enzymatic strategy was applied for the synthesis of a series of isosorbide 5- and 2-methacrylate derivatives. All the sythesized isosorbide monomethacrylates were radically polymerized with AIBN. The properties of these polymers with different side groups in either endo or exo configuration in the isosorbide structure was examined. The methacrylic isosorbide derivatives with OH-group were found to have very high glass transition temperature (Tg = 167 °C) and good thermal stability (at 5% weight loss under N2, Td,95 = 240 °C). The highest molecular weight (Mn = 80.6 kg/mol) was determined for the polymethacrylate with Ac-substitute.

摘要:The invention relates to the synthesis of isosorbide mononitrates. n The process according to the invention consists in reacting a hydrazine derivative with isosorbide dinitrate, in a polar solvent medium. The reaction is preferably carried out at the reflux temperature of the solvent medium, with an excess of the hydrazine derivative. A preferred solvent medium is a mixture of tetrahydrofuran and methanol. The process leads to the preferential formation of isosorbitol-2-mononitrate, which is a coronary vasodilator.
