Patent DE-19829511-A1 (DE)
Inventor: EHRFELD WOLFGANG
IPC: B01J4/00
Filed: 1998-07-02
Abstract: The invention relates to a method for producing propene oxide from propene and oxygen. According to a known method a gas stream containing propene and oxygen is guided over catalytically active materials. A disadvantage hereby is the low propene oxide yield and the high proportion of by-products. The aim of the invention is to provide a method offering a higher yield and lower proportion of by-products. To this end a first gas stream is guided over a suitable catalytically active material and  only thereafter a second gas stream containing oxygen is supplied. It is further possible to supply a third gas stream containing propene. Carrying out the reaction in at least two parts allows for separate optimization of reaction conditions and thus a reduction in the proportion of by-products.
