Abstract: Process for preparation of mono- or diesters of tetrahydrofuran homo- or copolymer by polymerisation of tetrahydrofuran in the presence of at least one telogen and/or comonomers using an acid catalyst where the polymerisation reactor is started with a mixture of polytetrahydrofuran, its mono- or diester and /or tetrahydrofuran copolymer, tetrahydrofuran, optionally a copolymer and at least one carboxylic acid and/or a carboxylic acid anhydride is new.

Abstract: A PROCESS FOR THE SEPARATION BY DISTILLATION OF A MIXTURE COMPRISING 1,4- BUTANEDIOL AND AT LEAST ONE FURTHER COMPOUND FROM THE GROUP CONSISTING OF 4-HYDROXYBUTYRALDEHYDE, ITS CYCLIC HEMIACETAL AND ITS CYCLIC FULL ACETALS WITH AT LEAST ONE FURTHER ALCOHOL COMPRISES CARRYING OUT THE DISTILLATION IN THE PRESENCE OF AN ALKALINE COMPOUND. THE MIXTURE TO BE SEPARATED PREFERABLY COMPRISES A CYCLIC FULL ACETAL OF 4-HYDROXYBUTYRALDEHYDE WITH A FURTHER ALCOHOL WHICH HAS A LOWER BOILING POINT THAN BUTANEDIOL AND ALSO THE FURTHER ALCOHOL IN FREE FORM. THE PROCESS IS PARTICULARLY SUITABLE FOR THE SEPARATION BY DISTILLATION OF MIXTURES FORMED IN THE HYDROGENATION OF MALEIC ACID DERIVATIVES.

Abstract: In a process for preparing pyrrolidone, which may be N-substituted, substrates selected from among C4-dicarboxylic acids and their derivatives are hydrogenated in the gas phase under anhydrous conditions with or without addition of ammonia or primary amines and using a Cr-free catalyst which comprises from 5 to 95% by weight of CuO, preferably from 30 to 70% by weight of CuO, and from 5 to 95% by weight of Al2O3, preferably from 30 to 70% by weight of Al2O3, and from 0 to 60% by weight, preferably from 5 to 40% by weight, of ZnO.

Abstract: A tetrahydrofuran-copolymer is obtained by co-polymerizing tetrahydrofuran with an alpha , omega -diol, in the presence of a heteropolyacid and a telogen. The telogen and/or diol are added in reactor (I) of the process. Water is distilled off directly from reactor (I), besides polymerization, throughout the reaction.
