Abstract: The invention relates to a method for producing monoisopropylamine (MIPA). According to the inventive method, propine and/or propadiene are reacted with MIPA under hydroamination conditions. The hydroamination product(s) obtained are then reacted with ammonia under transalkylation and hydrogenation conditions.

Abstract: Acrolein and acrylic acid are produced from propane and propene by absorption/desorption of propane and propene from a gas mixture followed by oxidation, in which no heterogeneously catalyzed dehydrogenation of propane occurs between the desorption and oxidation stages without addition of oxygen. Acrolein and acrylic acid are produced from propane and propene by: (a) separation of propane and propene from a gas mixture (A) by absorption in an absorption medium; (b) separation of propane and propene from the absorbent to give a mixture (B) containing propane and propene; and (c) using mixture (B) for oxidation to the required product(s). In this process, no catalytic dehydrogenation of propane without the addition of oxygen is carried out between stages (b) and (c).

Abstract: The invention relates to a method for combinatorially producing a library of materials by means of an electrochemical deposition in an array. The inventive library is made from an array of containers that consist of an electroconductive material, are open to the top and are electroconductively connected to a shared current supply device and is made from a corresponding array of auxiliary electrodes that are electroconductively connected to a shared current supply device and are arranged in such a way that an auxiliary electrode plunges into a container respectively or can be introduced therein without touching said container. The inventive method comprises the following steps: filling the containers with electrolytes having different compositions and containing electrolytically separable elements and applying an electric voltage between the current supply devices of the containers and auxiliary electrodes for obtaining an electrolytic deposition on the surfaces of the containers.

Abstract: The invention relates to a method for producing multi-metal oxide masses containing Mo, V, Cu and at least one of the elements W, Nb, Cr and Ce. In this method, a solid component with fine particles is formed and incorporated, at low temperature, in an aqueous solution of parent compounds of the residual multi-metal oxide constituents. The mixture is dried and then burnt.
