The present invention relates to a process for preparing 1-adamantyltrimethylammonium hydroxide, by A) reacting 1-adamantyldimethylamine with dimethyl sulfate to give 1-adamantyltrimethylammonium sulfate; and B) subjecting the 1-adamantyltrimethylammonium sulfate obtained in A) to anion exchange with an ion exchanger loaded with OH ions.

Method for producing 1-adamantyl trimethylammonium hydroxide

Process for preparing tri-n-propylamine (TPA), wherein di-n-propylamine (DPA) is reacted in the presence of hydrogen and a copper-comprising heterogeneous catalyst. An integrated process for preparing TPA, which comprises the following operations:

Process for preparing tri-n-propylamine (TPA)

A process for preparing butadiene, comprising A) providing a stream (a) comprising n-butane; B) feeding stream (a) comprising into at least one first dehydrogenation zone and nonoxidatively catalytically dehydrogenating n-butane to obtain a stream (b) comprising n-butane, 1-butene, 2-butene, butadiene, hydrogen and low-boiling secondary constituents; C) feeding stream (b) and an oxygenous gas into at least one second dehydrogenation zone and oxidatively dehydrogenating n-butane, 1-butene and 2-butene to obtain a stream (c) comprising n-butane, 2-butene, butadiene, low-boiling secondary constituents, carbon oxides and steam, wherein stream (c) has a higher content of butadiene than stream (b); D) removing the low-boiling secondary constituents and steam to obtain a stream (d) substantially consisting of n-butane, 2-butene and butadiene; E) separating stream (d) into a stream (e1) consisting substantially of n-butane and 2-butene and a stream (e2) consisting substantially of butadiene by extractive distillation; F) recycling stream (e1) into the first dehydrogenation zone.

Method for producing butadiene from n-butane

The invention relates to a process for preparing a catalyst support, in which zirconium dioxide powder is mixed with a binder, if desired a pore former, if desired an acid, water and, if desired, further additives to give a kneadable composition and the composition is homogenized, shaped to produce shaped bodies, dried and calcined, wherein the binder is a monomeric, oligomeric or polymeric organosilicon compound. Suitable binders are monomeric, oligomeric or polymeric silanes, alkoxysilanes, aryloxysilanes, acryloxysilanes, oximinosilanes, halosilanes, aminoxysilanes, aminosilanes, amidosilanes, silazanes or silicones. The invention also provides the catalyst support which has been prepared in this way, a catalyst comprising the support and its use as dehydrogenation catalyst.
