    Abstract: The invention relates to a process for distillative workup of a methanol/water mixture, in which a methanol/water mixture is added to a distillation column (1), an essentially methanol-comprising vapor stream is withdrawn at the top of the distillation column (1) and an essentially water-comprising bottom stream at the bottom of the distillation column (1), at least a portion of the essentially methanol-comprising vapor stream is compressed and the compressed vapor stream is added as heating vapor to an evaporator (11) in which at least a portion of the methanol/water mixture to be separated is evaporated. The invention further relates to a process for preparing alkali metal methoxides in a reaction column (31) by adding methanol and alkali metal hydroxide solution to the reaction column (31), withdrawing alkali metal methoxide dissolved in methanol at the lower end of the reaction column (31) and withdrawing a methanol/water mixture at the upper end of the reaction column (31), and working up the methanol/water mixture by the process for distillative workup.

    Abstract: Disclosed is a method for producing a catalyst containing vanadium, phosphorus, and oxygen, which is used for oxidizing the gas phase of a hydrocarbon having at least four carbon atoms to maleic anhydride. According to the inventive method, a corresponding catalyst precursor which contains vanadium, phosphorus, and oxygen and is provided with particles having an average diameter of at least 2 mm is converted into a catalytically active form by means of calcination, and a flow of the catalyst precursor is transported on a conveyor belt across at least one calcination area over a distance 1n at an essentially steady speed in order to be calcinated. The variation over time of the gas temperature in relation to the set point value amounts to ≦5° C. at each position in the area of the flow of the catalyst precursor, which lies within the second half 1n/2 of the calcination area, while the local difference in the gas temperature between any positions in the area of the flow of the catalyst precursor, which is located within the second half 1n/2 of the calcination area, amounts to ≦5° C.

    Abstract: A novel metal injection molding material contains a) from 40 to 70% by volume of metal powder, including at least 50% by weight, based on the total amount of metal, of an iron-containing powder, at least 90% by weight, based on the amount of this iron-containing powder, of the particles of which have an effective diameter of at least 40 micrometers, b) from 30 to 60% by volume of a thermoplastic binder and c) from 0 to 5% by volume of a dispersant and/or other assistants. This injection molding material is shaped by injection molding, the injection molded parts are freed from the binder and said parts freed from the binder are sintered.
