    Abstract: The invention concerns the production of a hydrogenation catalyser based on an aluminium/transition metal alloy. The proposed method involves producing a kneadable material from the alloy and an auxiliary agent, moulding the kneadable material into moulded articles, calcinating these articles and then treating them with an alkali metal hydroxide, using (a) polyvinyl alcohol and water or (b) stearic acid as the auxiliary agent. The invention also concerns methods of hydrogenation and hydrogenolysis, in particular the partial hydrogenation of aliphatic alpha , omega -dinitriles to alpha , omega -aminonitriles; and the use of the catalysers thus produced for hydrogenation and hydrogenolysis.

    Abstract: A description is given of a process for preparing methyl formate by reacting excess methanol with carbon monoxide under superatmospheric pressure and at elevated temperature in the presence of alkali metal methoxide or alkaline earth metal methoxide as catalyst in a pressure-rated reactor, in which the use of at least two reactor elements, preferably operated in countercurrent, at about 100° C. and a pressure of about 100 bar in combination with a solids-free desalting of the reaction product makes possible very economical, largely trouble-free production of methyl formate in any desired quality and with a very good production capacity. Furthermore, the process for solids-free desalting and apparatuses for carrying out this process are described.

    Abstract: The invention relates to a process for obtaining anhydrous or substantially anhydrous formic acid, in which firstly aqueous formic acid is produced by hydrolysis of methyl formate, with the methanol content in the methyl formate having been reduced in advance. The process according to the invention has the special feature that-before the hydrolysis of the methyl formate-the methanol content of the methanol-containing methyl formate is reduced in a distillation column, this distillation column simultaneously being employed for other separation functions during work-up of the formic acid.
