This article deals with the impact of a vaporization surface in the brewing industry. The vaporization surface is deemed to have a positive impact on the evaporation quality of unwanted flavour components -especially dimethyl sulphide. Based on physicoprocedural considerations and trials, the current article deduces and verifies that an increased vaporization surface does not have an enhancing impact on evaporation quality.

The synthesis of quinolines from alcohols and 2‐nitrobenzaldehydes is described. Unreactive alcohols and 2‐nitrobenzaldehydes were concurrently converted to the reactive reactants for a Friedländer annulation via a hydrogen transfer. Tris(triphenylphosphine)ruthenium(II) dichloride [Ru(PPh3)3Cl2] appeared to serve the dual role of an efficient hydrogen transfer catalyst and a suitable Friedländer annulation catalyst.
