标题:萘一步一步催化胺化为萘胺
摘要:将芳族化合物一步胺化成芳基胺是一种有前途的策略,具有较高的原子经济性和较少的环境污染.我们首次提出在温和的条件下使用钒催化剂将萘直接催化胺化成萘胺和羟胺.在萘的一步胺化反应中,以v 2 O 5 / Hzsm-5催化剂的收率获得萘胺的收率为70%,该产率高于通过现有技术方法获得的收率.V 2 O 5 / Hzsm-5催化剂中的布朗斯台德酸位以及单钒酸盐的v-o-v和v O键是胺化反应的活性位点,负责萘的活化和nh 3 +的形成作为活性胺化试剂.通过研究实时ir和原位drifts,还提出了可能的反应机理.提议的萘一步一步胺化工艺优于传统的非选择性硝化和氢化工艺,一些发现为从芳族化合物生产芳胺提供了新的见解.

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.
