    Abstract: PROBLEM TO BE SOLVED: To provide a method for fractionating an amine-containing mixture. SOLUTION: According to circumstances, (i) a (first) low boiling point matter fraction is separated and removed from the amine-containing mixture by distillation, according to circumstances, (ii) a (first) high boiling point matter fraction is separated and removed from the amine-containing mixture by distillation, (iii) the amine-containing mixture is subjected to extraction using a sodium hydroxide solution to produce a sodium hydroxide-containing aqueous first phase and an amine-, (further) low boiling point matter- and, according to circumstances, (further) high boiling matter-containing water-organic second phase, (iv) the water-organic second phase is distilled to produce a substantially anhydrous amine as a column bottom phase taken-out substance or as a lateral flow extract in the stripping part of a distillation column, an amine/water azeotropic mixture as a lateral flow extract in the concentration part of the column and a (further) low boiling matter fraction as a column top extract and the amine/water azeotropic mixture is returned to the extraction process (iii) and, according to circumstances, (v) the substantially anhydrous amine is refined or fractionated.

    Abstract: PCT No. PCT/EP96/03472 Sec. 371 Date Feb. 12, 1998 Sec. 102(e) Date Feb. 12, 1998 PCT Filed Aug. 6, 1996 PCT Pub. No. WO97/07111 PCT Pub. Date Feb. 27, 1997A process for the preparation of butyrolactones of the formula I where the substituents R1 and R2 are hydrogen, alkyl or hydroxyalkyl groups, or aryl and trialkylsilyl groups, if appropriate carrying inert: substituents, is described in which an alkyne of the formula IIR1-C 3BOND C-R2IIwhere the substituents have the meanings indicated above, is reacted under reducing conditions at elevated pressure and elevated temperature with carbon monoxide CO and hydrogen in the presence of a transition metal catalyst or with carbon monoxide and water in the presence of a transition metal catalyst.

    Abstract: The invention relates to a method for producing polytetrahydrofuran and polytetrahydrofuran copolymers, diesters or monoesters thereof by polymerising tetrahydrofuran in the presence of at least one telogen and/or comonomer on acid- activated montmorillonite catalysts, whereby the ratio of the montmorillonite structure to the sum of the muscovite and kaolin structure in the montmorillonite catalyst, which is determined from the intensities of the reflexes measured at 5.5~ 2È for montmorillonite, 9.0~ 2È for muscovite and 12,5~ 2È for kaolin is, after acid activation, at least 5:1.
