Abstract: A process for preparing polyetherols by ring-opening polymerization of alkylene oxides onto H-functional initiator molecules, which comprises at least one process step a) in which a compound of the formula (I) M'aM''b(OH)cOd*Ac*Lf (I), applied to a solid inert support or incorporated in the latter or molded to form a shaped body is used as catalyst, and at least one process step b) in which a multimetal cyanide compound of the formula (II) M1a[M2(CN)b(A)c]d.fM1gXn.h(H2O).eL (II) applied to a solid, inert support or incorporated in the latter or molded to form a shaped body or in powder or paste form is used as catalyst.

Abstract: The invention relates to a method for producing a titanium silicate with RUT structure, which consists of the following steps: (i) preparation of a mixture of at least one SiO2 source and at least one titanium source; and (ii) crystallization of the mixture prepared in (i) in a pressurized vessel with addition of at least one template compound so that a suspension is obtained. The method is characterized in that amines or ammonium salts suitable for stabilizing cages of the silicate structure [4 5 6 ] and [4 5 6 8 ] are used as template compound.

Abstract: A process for oxidizing an organic compound having at least one C-C double bond or a mixture of two or more thereof comprises the following steps:(I) preparing a hydroperoxide,(II) reacting an organic compound having at least one C-C double bond or a mixture of two or more thereof with the hydroperoxide prepared in step (I) in the presence of a zeolite catalyst,(III) regenerating the at least partially deactivated zeolite catalyst used in step (II), and(IV) conducting the reaction of step (II) using a zeolite catalyst containing the catalyst regenerated in step (III).
