摘要:在这项研究中,负载在氧化铝二氧化硅上的铑-镍双金属纳米颗粒(rhni / Al-Sba-15)被用作水中邻苯二甲酸酯加氢的催化剂,以生产环境可接受的非邻苯二甲酸酯增塑剂.化学流体沉积(cfd)用于将金属掺杂到氧化铝载体上,这有助于在al-Sba-15上形成rhni的均匀结构.Ni的引入通过减小双金属纳米颗粒的尺寸帮助减少了昂贵的rh的使用并增加了金属活性位点的数量.铝化的sba-15不仅充当rhni双金属催化剂的载体,而且还通过引入brønsted和lewis酸位以及水中邻苯二甲酸酯在催化剂上的吸收来提高反应效率.制备的催化剂的理化性质用n表征2吸附-解吸等温线,X射线衍射(xrd),原位漫反射红外傅里叶变换光谱(drifts),扫描电子显微镜(sem)和透射电子显微镜(tem).用邻苯二甲酸二甲酯(dmp)的氢化作用评价了合成催化剂的催化性能.尽管dmp在水中的溶解度较低,但使用rh 0

标 题:Device for the synthesis of a polymer with extraction of a gaseous substance comprising a reaction chamber having at least one circular-cylindrical section
发明人：ZHU NING; STAMMER ACHIM; CLAUSS JOACHIM; KORY GAD
权利人:BASF SE
摘要:An apparatus for synthesis of a polymer with separation of a gaseous substance comprises a reaction space having an essentially circular cylindrical upper section which is bounded by two circular faces and one shell face and has a longitudinal cylinder axis, and a lower section, an inlet orifice disposed in a circular face or the shell face of the upper section, a first outlet orifice disposed in a wall of the lower section, a second outlet orifice disposed in the shell face of the upper section opposite the first outlet orifice, and a removal device which is disposed so as to be rotatable about the longitudinal cylinder axis and is in contact with both circular faces and the shell face. This apparatus can especially be used for performance of a process including the feeding of an oligomer melt into a reaction space through an inlet orifice, the polymerization of the oligomer melt to give a polymer melt, the removal of the polymer melt from the reaction space through a first outlet orifice of the reaction space, and the removal of a gaseous substance from the reaction space through a second outlet orifice of the reaction space, wherein deposits on at least one inner wall of the reaction space are removed by a removal device and transported into the oligomer melt.

标 题 :Synthesis of surface-functionalized polyamides
发明人：HABRAKEN GIJSBRECHT JACOBUS MARIA; SPRAFKE JOHANNES KLAUS; DA SILVA MARION
权利人:BASF SE
摘要:The present invention relates to a process for producing a surface-functionalized molding (oF) having a functionalized surface (fO). In this process a surface (O) of a molding (F) is brought into contact with a dienophile-containing solution (dL). The surface (O) comprises a polyamide (P) which comprises furan units. These furan units are able to react with the at least one dienophile present in the dienophile-containing solution (dL) to give the surface-functionalized molding (oF) having the functionalized surface (fO).

摘要:The present invention relates to an isocyanate-free and preferably solvent-free process for preparing polymers containing five-membered cyclic carbonate groups. In particular, the present invention is directed to a process for preparing polymers bearing cyclic carbonate groups by reacting carboxyl-bearing polymers selected from the group including polyesters based on di- or polyols and di- or polycarboxylic acids or derivatives thereof or poly(meth)acrylates, with hydroxyl-functionalized five-membered cyclic carbonates, without addition of isocyanates.
