Abstract: IN A PROCESS FOR CONCENTRATING AN AT LEAST PARTIALLY CRYSTALLINE SOLID CONTAINING AT LEAST ONE ZEOLITE IN A MIXTURE COMPRISING AT LEAST ONE AUXILIARY, FOR EXAMPLE A TEMPLATE COMPOUND, AND SAID SOLID , THE MIXTURE IS ULTRAFILTRATED IN A STEP (II) TO DIVIDE THE MIXTURE INTO A RETENTATE AND A PERMEATE, THE SOLIDS CONTENT IN THE RETENTATE BEING HIGHER THAN THAT IN THE MIXTURE AND THE SOLIDS CONTENT IN THE PERMEATE BEING LOWER THAN THAT IN THE MIXTURE. THIS PROCEDURE ALLOWS AUXILIARIES, IN PARTICULAR TEMPLATE COMPOUNDS , PRESENT IN THE PERMEATE TO BE RECYCLED INTO A CRYSTALLIZATION STEP (I) UPSTREAM OF STEP (II).

Abstract: Preparation of a solid (I) containing silicon dioxide includes the stage of contacting at least one precursor (II) for SiO2 with at least one structure former in a liquid medium. The novelty is that the structure former comprises a polyethyleneimine (PEI) or a mixture of two or more PEI's. Also claimed are (I) obtained by the process; and the use of PEI (or a mixture of PEI's) as structure former in the preparation of solids containing SiO2.

Abstract: The invention concerns a process for preparing polytetrahydrofuran, copolymers of tetrahydrofuran and 2-butin-1,4-diol, diesters of these polymers with C2-C20 monocarboxylic acids or monoesters of these polymers with C1-C10 monocarboxylic acids by polymerizing tetrahydrofuran in the presence of one of the following telogens, water, 1,-4-butane diol, 2-butin-1,4-diol, polytetrahydrofuran with a molecular weight of between 200 and 700 Dalton, or of a C1-C10 monocarboxylic acid or a carboxylic acid anhydride produced from C2-C20 monocarboxylic acids or mixtures of these telogens on a heterogeneous carrier catalyst which contains a catalytically active amount of an oxygenous molybdenum and/or tungsten compound on an oxidic carrier material, and which has been calcined at temperatures of between 500 DEG C and 1000 DEG C after application of the precursor compounds of the oxygenous molybdenum and/or tungsten compounds to the carrier material precursors. Before it is used as a polymerization catalyst, the catalyst is activated by treatment with a reducing agent.
