标题:Ag-Ceox/mcm-41 催化四氢糠醇选择性氧化反应生成2-甲基四氢呋喃
摘要:四氢糠醇(Thfa)是制备呋喃类化合物的重要原料.在此,我们首次采用无溶剂技术以thfa(thfa的开环和闭环)为原料成功合成了2-甲基四氢呋喃(2-Mthf).采用浸渍法合成了ag-Ceo X /mcm-41催化剂. N 2吸附-解吸,Hr-Tem,Xrd,Xps 和 Py-Ir 对催化剂进行了表征.验证了ag-Ceo X /mcm-41 催化剂表面存在 Ce 4+ /ce 3+氧化还原对和 Ag Np (Ag 0 ). Ag和ce在催化剂表面的协同作用,L酸的富集和少量b酸中心是thfa选择性氧化为2-Mthf的关键因素.实验结果表明,在150°C,4 Mpa O 2压力,1 G催化剂的反应条件下,Thfa转化率为100%,2-Mthf选择性为68.11%.我们的研究结果提供了一种从 Thfa 制备 2-Mthf 的高效方法.

发明人：ROOS SEBASTIAN; EISENBERG BORIS; HARPE CAROLIN
权利人:ROHMAX ADDITIVES GMBH
摘要:The present invention relates to a process for synthesis of polymer compositions with reduced catalyst content, wherein ethylenically unsaturated monomers containing less than 0.5 wt % of ethylenically unsaturated monomers with at least one carboxylic group, sulfonic acid group and/or at least one phosphonic acid group relative to the total weight of the ethylenically unsaturated monomers are polymerized by means of initiators containing a transferable group of atoms and of one or more catalysts comprising at least one transition metal in the presence of ligands which can form a coordination compound with the metal catalyst or catalysts and, after the polymerization, the catalyst contained in the polymer is at least partly separated. For this purpose, the polymer composition is filtered, after the polymerization, in the presence of at least one filter aid which contains at least 0.5 wt %, relative to the total weight of the filter aid, of repeating units that contain at least one carboxylic acid group, sulfonic acid group and/or at least one phosphonic acid group.

摘要:A self-healing polymer material that includes a multiphase copolymer, and a method of making the copolymer, are provided. The multiphase copolymer includes one or more hydrogen bond-forming copolymer segments, each segment including a polymerized acrylamide monomer and a polymerized acrylic monomer. The polymerized acrylamide monomer includes functional groups that form hydrogen bonds in the multiphase copolymer, and is present in the one or more copolymer segments in an amount sufficient for self-healing of the multiphase copolymer.

摘要:The invention relates to a process for preparing polymers for coating applications by polymerizing esters of acrylic acid or of methacrylic acid or vinyl aromatics or other free-radically polymerizable vinyl compounds or monomer mixtures composed predominantly of such monomers by means of a continuous polymerization process. In particular, the invention relates to a solvent-free preparation process for polymers, through which the binder can be prepared for coating applications with superior processing properties, very good thermal stability, improved pigment wetting and a higher gloss.
