Abstract:
The invention relates to a catalytically active body for the synthesis of dimethyl ether from synthesis gas. In particular, the invention relates to an improved catalytically active body for the synthesis of dimethyl ether, whereby the components of the active body comprise a methanol active component and an acid component comprising a zeolitic material being crystallized by means of one or more alkenyltrialkylammonium cation R 1 R 2 R 3 R 4 N + -containing compounds as structure directing agent. Furthermore, the present invention concerns a method for the preparation of a catalytically active body, the use of the catalytically active body and a method for the preparation of dimethyl ether from synthesis gas.
Abstract:
The invention relates to a catalyst complex comprising boron trifluoride and a co-catalyst mixture of 10 to 90 wt% of a monovalent primary C 1 to C 20 alcohol and 90 to 10 wt% of a monovalent secondary C 3 to C 20 alcohol, wherein the molar ratio of boron trifluoride to the sum of all alcohols is 2:1 to 1:10. Said catalyst complex is used in the production of highly reactive isobutene homopolymers having a number-average molecular weight of 300 to 50,000, wherein a C 4 hydrocarbon mixture containing at least 20 wt% of isobutene and in total at least 10 wt% of other C 4 olefins is used as a feed material.
Abstract:
The invention relates to a method for producing rigid polyurethane foams or rigid polyisocyanurate foams using certain polyether ester polyols (B) based on aromatic dicarboxylic acids, optionally additional polyester polyols (C) different from the polyols of component (B), and polyether polyols (D), wherein the mass ratio of the sum of components (B) and, if applicable, (C) to component (D) is less than 1.6. The invention also relates to the rigid foams that can thus be obtained and to the use thereof for producing sandwich elements having rigid or flexible cover layers. The invention further relates to the basic polyol components.
