Patent number: 6300467Abstract: The present invention relates to a process for preparing hydroxyl-containing polymers, in particular for preparing polytetrahydrofuran with terminal hydroxyl groups, from the corresponding acyloxy-containing polymers by transesterification with alcohols in the presence of an alkali metal- or alkaline earth metal-containing catalyst, which entails the appropriate acyloxy-containing polymer being introduced together with the alcohol and the catalyst into a first prereactor (I) and converted therein at least partly to the hydroxyl-containing polymer, and the reaction solution being fed into the upper zone (IIa) of a distillation column (II) into whose lower zone (IIb) alcohol in vapor phase is additionally fed. This involves a phase exchange at the coherent and the disperse phase at the transition from the prereactor to the distillation column. Preferably, in addition to the first prereactor, a further 3 prereactors are used which serve as holdup reactors.Type: GrantFiled: March 29, 2000Date of Patent: October 9, 2001Assignee: BASF AktiengesellschaftInventors: Heinz Auer, Jürgen Ciprian, Lothar Franz, Wolfgang Franzischka, Gabriele Iffland, Alexander Weck, Werner Weinle

Patent number: 6037381Abstract: The invention relates to a process for preparing hydroxyl-containing polymers, in particular for preparing polytetrahydrofuran with terminal hydroxyl groups, from the corresponding acyloxy-containing polymers by transesterification with alcohols in the presence of a sodium-containing catalyst. In this process the polytetrahydrofuiran solution is passed in the presence of a catalytic amount of water directly through at least one ion exchanger following the transesterification in order to remove the sodium cations.The novel process makes it possible to remove the sodium cations from the sodium-containing catalyst in an economic manner and with little complexity. The residual sodium content can be reduced to values of less than 0.5 ppm.Type: GrantFiled: December 28, 1998Date of Patent: March 14, 2000Assignee: BASF AktiengesellschaftInventors: Wulfrich Friedemann Beer, Klaus Beiser, Jurgen Ciprian, Lothar Franz, Wolfgang Franzischka, Christof Palm, Frank-Friedrich Pape, Axel Paul, Ulrich-Dieter Pessel, Alexander Weck

Patent number: 5981688Abstract: A process for preparing hydroxyl-containing polymers and, in particular, a process for preparing polytetrahydrofuran with terminal hydroxyl groups from the corresponding acyloxy-containing polymers by transesterification with alcohols is carried out continuously in at least one stirred vessel, with the foam produced in the transesterification being fed tangentially to a cylindrical container, preferably a cyclone separator, at an adequate velocity to destroy the foam. The liquid phase which separates out is recycled through a line to the at least one stirred vessel.This continuous process is preferably carried out in a cascade of stirred vessels, in which each stirred vessel or a subunit of at least two stirred vessels can in each case be coupled to a cylindrical container, preferably in the form of a cyclone separator.Type: GrantFiled: September 23, 1998Date of Patent: November 9, 1999Assignee: BASF AktiengesellschaftInventors: Heinz Auer, Klaus Beiser, Jurgen Ciprian, Lothar Franz, Wolfgang Franzischka, Ulrich-Dieter Pessel, Werner Weinle
