Abstract: The invention relates to a method for isolating concentrated paraffin sulfonic acids from reaction mixtures that are produced during the sulfoxidation of n-paraffins, from which a major part of the sulfuric acid and the paraffin was removed by phase separation and which contain, in addition to the free paraffin sulfonic acids, n-paraffins, water and optionally minor amounts of sulfuric acids. The method according to the invention is characterized by removing paraffin and optionally residual water by vacuum distillation. The paraffin sulfonic acids obtained by distillation have a content of more than 85% by weight of the active substance. The material is pale, odorless and low in sulfuric acid and paraffin.

Abstract: A process for preparing solid alkaline earth metal salts of secondary paraffinsulphonic acids is claimed. This process comprises converting an aqueous solution of a secondary paraffinsulphonic acid and an alkaline earth metal hydroxide into solid form by spray drying.

Abstract: The invention relates to a one-pot reaction for the production of 3,7-diaza-bicyclo[3.3.1]nonane compounds, wherein in a first step a dicarboxylic acid ester is reacted with a pyridine aldehyde and a primary amine. The piperidone created in this manner is reacted with formaldehyde and a further primary amine in a second step. It is essential to the invention that both reaction steps are carried out in a one-pot variation in a C1-C4 alcohol as the solvent, and that the reaction water created is removed by means of distillation.
