Abstract: Bis-(aminocyclohexyl)-dialkyl-methanes of the general formula I where R1 and R2 are identical or different and are each lower alkyl, R3 is hydrogen or lower alkyl, and the two cyclohexane rings may be unsubstituted or substituted, are prepared by a process in which a para-unsubstituted aniline is condensed with a lower aliphatic ketone in the presence of a strong acid, and the product obtained is then hydrogenated in the presence of a ruthenium-containing catalyst.

Abstract: Methyl formate is prepared by reaction of carbon monoxide and methanol at elevated pressure and elevated temperature in the presence of an alkali metal methoxide by A) mixing the starting substances in a mixing zone, partially allowing them to react, saturating the reaction solution with CO and B) carrying the reaction to completion in one or more subsequent reaction zones without addition of further starting compounds.
