The invention relates to a method for producing CO2 for attracting bloodsucking arthropods (). In this method, at least one liquid or solid organic substance () is reacted in an oxidation process in a targeted manner, one portion completely and another partially, thus forming, in addition to CO2, H2O and heat, at least one further partial oxidation product (P). The invention further relates to a device () for generating CO2, said device () comprising a storage means () for at least one liquid or solid organic substance () and an evaporation module () for the liquid or solid organic substance (). The device () comprises a reactor module () for the controlled oxidation and partial oxidation of the at least one liquid or solid organic substance (); a control unit (); and means () for regulating the oxidation and partial oxidation process. The means () for regulating the oxidation and partial oxidation process can be regulated via the control unit (), hence allowing defined reaction conditions to be set in the reactor module () for the targeted control of the oxidation and partial oxidation process.

The invention provides a method to produce primary diamines by catalytic conversion of diols having a linear main chain of from 4 to 31 carbon atoms into the corresponding diamines. The reaction is conducted in a liquid or supercritical phase and is catalyzed by a homogeneous ruthenium-containing complex. The primary diamines obtained may be suitable for polyamide syntheses.
